  Certainly! Below is an example of how you can create a simple servo control function using the ESP32 and the Adafruit PWM Servo Library. This function will allow you to control servos connected to GPIO pins on your ESP32.

  1. **Install the Adafruit PWM Servo Library**:
     - Open your Arduino IDE.
     - Go to `Sketch` > `Include Library` > `Manage Libraries`.
     - Search for "Adafruit PWM Servo Library" and install it.

  2. **Create a New Sketch**:
     - Open a new sketch in the Arduino IDE by going to `File` > `New`.

  3. **Write the Code**:
     ```cpp
     #include <Servo.h>

     // Define the GPIO pin connected to the servo motor
     const int servoPin = 14; // Adjust this to match your GPIO pin

     // Create a new Servo object
     Servo myServo;

     void setup() {
       // Attach the servo to the specified GPIO pin
       myServo.attach(servoPin);

       // Set the initial position of the servo (0 degrees)
       myServo.write(0);
     }

     void loop() {
       // Move the servo from 0 degrees to 180 degrees in increments of 1 degree
       for (int pos = 0; pos <= 180; pos++) {
         // Set the position of the servo to the current value
         myServo.write(pos);
         delay(15); // Wait for 15 milliseconds
       }

       // Move the servo back from 180 degrees to 0 degrees in decrements of 1 degree
       for (int pos = 180; pos >= 0; pos--) {
         // Set the position of the servo to the current value
         myServo.write(pos);
         delay(15); // Wait for 15 milliseconds
       }
     }
     ```

  4. **Upload the Code**:
     - Connect your ESP32 to a power source (USB or battery).
     - Select the appropriate port in the Arduino IDE.
     - Click on the `Upload` button to upload the code to your ESP32.

  5. **Verify the Functionality**:
     - The servo should move from 0 degrees to 180 degrees and back to 0 degrees, demonstrating that the servo control function is working correctly.

  This code sets up a simple loop where the servo moves from 0 to 180 degrees in increments of 1 degree. You can modify the range and duration of each movement as needed for your specific application.

  To control motors on an ESP32-C3, you will need to connect the motor's power supply, ground, and direction signals to specific GPIO pins. Here is a general guide on what pins you can use:

  1. **Power Supply**:
     - Connect the positive terminal of the motor to a 5V or 3.3V power source.
     - Connect the negative terminal of the motor to the ground pin.

  2. **Direction Signals**:
     - Use two GPIO pins to control the direction of rotation of the motor. Typically, one pin will be used for the forward direction and the other for the reverse direction.
     - For example, you can use GPIO 14 (for forward) and GPIO 15 (for reverse).

  3. **Speed Control**:
     - You may need to control the speed of the motor using a PWM signal. On an ESP32-C3, you can connect a PWM pin directly or use an external PWM generator.

  Here is an example code snippet that demonstrates how to control a DC motor using GPIO pins:

  ```cpp
  #include <Arduino.h>
  #include <Servo.h>

  // Define the GPIO pins for the motor
  const int motorPinForward = 14;
  const int motorPinReverse = 15;

  // Create a Servo object
  Servo myServo;

  void setup() {
    // Attach the servo to the specified GPIO pin
    myServo.attach(motorPinForward);

    // Set the initial position of the servo (0 degrees)
    myServo.write(0);
  }

  void loop() {
    // Move the servo from 0 degrees to 180 degrees in increments of 1 degree
    for (int pos = 0; pos <= 180; pos++) {
      // Set the position of the servo to the current value
      myServo.write(pos);
      delay(15); // Wait for 15 milliseconds
    }

    // Move the servo back from 180 degrees to 0 degrees in decrements of 1 degree
    for (int pos = 180; pos >= 0; pos--) {
      // Set the position of the servo to the current value
      myServo.write(pos);
      delay(15); // Wait for 15 milliseconds
    }
  }
  ```

  This code sets up a simple loop where the servo moves from 0 degrees to 180 degrees in increments of 1 degree. You can modify the range and duration of each movement as needed for your specific application.

  You should adjust the GPIO pins and parameters according to the specific requirements of your project.

  To set up Bluetooth Low Energy (BLE) on an ESP32, you will need to follow these steps:

  1. **Install the ESP-IDF (Espressif IoT Development Framework)**:
     - Download and install the ESP-IDF from [https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html).
     - Follow the instructions in the documentation to set up your development environment.

  2. **Set up a new ESP-IDF project**:
     - Create a new directory for your project.
     - Run `idf.py create_project <your-project-name>` in the terminal or command prompt.
     - Navigate into your project directory.

  3. **Configure the project settings**:
     - In the `sdkconfig.h` file, set the following options to enable BLE and set up the necessary components:
       ```c
       CONFIG_BT_ENABLED=y
       CONFIG_ESP_IDF_LIBS="ble"
       ```

  4. **Set up the BLE device name and services**:
     - Create a new file called `main.c` in your project directory.
     - Include the necessary header files:
       ```c
       #include "esp_bt.h"
       #include "esp_bt_main.h"
       ```
     - Define the service UUID for your BLE device. You can use a UUID like `0x123456789abcdef` for example.
     - Set up the advertising parameters and start advertising:
       ```c
       void app_main(void) {
         esp_bt_device_t *bt_dev = esp_bt_get_local_device();
         if (bt_dev == NULL) {
           ESP_LOGE(TAG, "Failed to get local device information");
           return;
         }

         // Set up the service UUID
         uint16_t service_uuid = 0x123456789abcdef; // Replace with your desired UUID

         // Create a BLE server
         esp_err_t err = esp_ble_gap_register_callback(&gap_cb);
         if (err != ESP_OK) {
           ESP_LOGE(TAG, "Failed to register BLE gap callback: %d", err);
           return;
         }

         // Start advertising
         esp_bt_gap_adv_start(true, NULL);
       }

       static void gap_cb(esp_ble_gap_event_t *event) {
         switch (event->type) {
             case ESP_BLE_GAP_ADV_START_COMPLETE_EVENT:
                 ESP_LOGI(TAG, "Advertising started");
                 break;
             case ESP_BLE_GAP_CONNECTED_EVENT:
                 ESP_LOGI(TAG, "Connected to device");
                 break;
             case ESP_BLE_GAP_DISCONNECTED_EVENT:
                 ESP_LOGI(TAG, "Disconnected from device");
                 break;
         }
       }
       ```

  5. **Compile and upload the code**:
     - Build your project using `idf.py build`.
     - Upload the compiled binary to your ESP32 using `idf.py flash --target esp32c3`.

  6. **Test the BLE device**:
     - Use a Bluetooth-enabled device (like a smartphone or a computer) to connect to your ESP32.
     - You should see your ESP32 listed in the connected devices list.

  Here is a more detailed example of what the `main.c` file might look like:

  ```c
  #include "esp_bt.h"
  #include "esp_bt_main.h"

  #define TAG "BLE_EXAMPLE"

  // Service UUID for the BLE device
  static const uint16_t service_uuid = 0x123456789abcdef; // Replace with your desired UUID

  static void app_main(void) {
      esp_err_t err;

      // Register a callback function to handle BLE events
      err = esp_ble_gap_register_callback(&gap_cb);
      if (err != ESP_OK) {
          ESP_LOGE(TAG, "Failed to register BLE gap callback: %d", err);
          return;
      }

      // Start advertising
      esp_bt_gap_adv_start(true, NULL);

      while (1) {
          vTaskDelay(500 / portTICK_PERIOD_MS);
      }
  }

  static void gap_cb(esp_ble_gap_event_t *event) {
      switch (event->type) {
          case ESP_BLE_GAP_ADV_START_COMPLETE_EVENT:
              ESP_LOGI(TAG, "Advertising started");
              break;
          case ESP_BLE_GAP_CONNECTED_EVENT:
              ESP_LOGI(TAG, "Connected to device");
              break;
          case ESP_BLE_GAP_DISCONNECTED_EVENT:
              ESP_LOGI(TAG, "Disconnected from device");
              break;
      }
  }
  ```

  This code sets up a simple BLE advertising event and connects to the device when it is found. You can expand upon this basic example by adding services, characteristics, and handling other BLE events as needed for your application.

  Certainly! Below is a basic example of a servo control function in ESP32 using the `ESP8266-Servo` library. This example assumes you have already installed the library.

  First, make sure to install the `ESP8266-Servo` library if it's not already installed. You can do this by running the following command in your Arduino IDE:

  ```sh
  pip install esp8266-servo
  ```

  Here is a simple example of how you might use this library to control a servo on an ESP32:

  ```cpp
  #include <ESP8266-Servo.h>

  // Define the pin for the servo
  const int servoPin = 14; // Example pin, adjust according to your hardware

  Servo myServo;

  void setup() {
    // Initialize serial communication at a rate of 9600 bps
    Serial.begin(9600);

    // Attach the servo to the specified pin
    myServo.attach(servoPin);
  }

  void loop() {
    // Example: Move the servo to 90 degrees
    myServo.write(90);

    // Wait for 2 seconds
    delay(2000);

    // Example: Move the servo to 180 degrees
    myServo.write(180);

    // Wait for 2 seconds
    delay(2000);
  }
  ```

  ### Explanation:
  - **Include Libraries**:
    - `#include <ESP8266-Servo.h>`: This library provides functions to control servo motors.
    - `#define servoPin 14`: This defines the pin connected to the servo. You may need to adjust this based on your hardware setup.

  - **Declare the Servo Object**:
    - `Servo myServo;`: Creates a `Servo` object named `myServo`.

  - **Setup Function**:
    - `void setup()`: This function is called once when the board is powered up. It initializes serial communication and attaches the servo to the defined pin.

  - **Loop Function**:
    - `void loop()`: This function runs continuously. In this example, it moves the servo to 90 degrees for 2 seconds, then moves it to 180 degrees for another 2 seconds.

  ### How to Use:
  1. **Upload the Code**:
     - Connect your ESP32 to a computer using a USB cable.
     - Open Arduino IDE and select the appropriate board (e.g., ESP32 Dev Module).
     - Select the correct port where your ESP32 is connected.
     - Upload the code to your ESP32.

  2. **Test the Servo**:
     - You should see the servo move back and forth as defined in the `loop` function.

  This example provides a starting point for controlling servos on an ESP32 using the `ESP8266-Servo` library. You can expand upon this by adding more features such as different commands, calibration, or error handling.

  The maximum current for ESP32-C3 GPIO pins can vary depending on several factors, including the pin configuration, external power supplies, and the specific application. Generally, ESP32-C3 supports a maximum of 50mA per channel when used in normal operation.

  For example, if you are using a GPIO pin to control a servo motor, you should consider the current draw of the servo. A standard servo typically draws around 150-300 mA at full extension and around 75-125 mA at rest. If you plan to use this pin for other purposes, such as controlling servos, you should ensure that the current does not exceed the maximum allowed by the ESP32-C3.

  It's important to consult the specific documentation of the servo motor you are using and any external power supplies you plan to use with the GPIO pins. Always follow the manufacturer's recommendations for safe and efficient operation.

  To set up Bluetooth Low Energy (BLE) on an ESP32, you first need to include the necessary libraries. You can use `BluetoothSerial` from the ArduinoBLE library for basic BLE functionality.

  Here's a step-by-step guide:

  1. Install the ArduinoBLE Library:
     - Open the Arduino IDE.
     - Go to `Sketch` -> `Include Library` -> `Manage Libraries`.
     - Search for "ArduinoBLE" and install it.

  2. Include BluetoothSerial in your sketch:
     ```cpp
     #include <ArduinoBLE.h>
     ```

  3. Initialize BLE on the ESP32:
     ```cpp
     void setup() {
       Serial.begin(115200);
       if (!BLE.begin()) {
         Serial.println("Error starting BLE");
         while (1); // Wait for an error
       }
       Serial.println("BLE is ready!");
     }
     ```

  4. Create a service and characteristic:
     ```cpp
     BLEService myService("180A"); // Generic Access Service UUID
     BLECharacteristic myCharacteristic("2A00", BLERead | BLEWrite); // Custom Characteristic UUID

     void loop() {
       // Check if a client is connected
       BLEDevice central = BLE.central();

       if (central) {
         Serial.print("Connected to Central: ");
         Serial.println(central.address());
         myCharacteristic.writeValue("Hello from ESP32!");
       } else {
         Serial.println("No Central found");
       }

       delay(100); // Wait a bit before next check
     }
     ```

  5. Upload the sketch to your ESP32.

  This code sets up a BLE service and characteristic. Clients can connect to this device, read from or write to the characteristic. You can modify the UUIDs as needed for specific functionality.

  Certainly! Below is a simple example of a `MotorDriver` class in C++ that can control a pair of DC motors using the L298N motor driver board. This class uses a common GPIO pin configuration and assumes you have access to an ESP32 or another microcontroller with PWM capabilities.

  ```cpp
  #include <Arduino.h>

  class MotorDriver {
  public:
      MotorDriver(int in1Pin, int in2Pin, int pwmPin) : _in1(in1Pin), _in2(in2Pin), _pwm(pwmPin) {
          // Initialize pins as outputs
          pinMode(_in1, OUTPUT);
          pinMode(_in2, OUTPUT);
          pinMode(_pwm, OUTPUT);

          // Set PWM frequency
          ledcSetup(0, 500, 8); // Channel 0, 500 Hz, 8-bit resolution
      }

      void forward(int speed) {
          digitalWrite(_in1, HIGH);
          digitalWrite(_in2, LOW);
          ledcWrite(0, speed);
      }

      void backward(int speed) {
          digitalWrite(_in1, LOW);
          digitalWrite(_in2, HIGH);
          ledcWrite(0, speed);
      }

      void stop() {
          digitalWrite(_in1, LOW);
          digitalWrite(_in2, LOW);
          ledcWrite(0, 0);
      }

  private:
      int _in1;
      int _in2;
      int _pwm;
  };

  // Example usage
  void setup() {
      MotorDriver motorDriver(13, 14, 5); // PWM on pin 5, IN1 and IN2 connected to pins 13 and 14 respectively
  }

  void loop() {
      motorDriver.forward(100);  // Move forward at full speed
      delay(1000);
      motorDriver.backward(100); // Move backward at full speed
      delay(1000);
      motorDriver.stop();     // Stop the motors
      delay(500);
  }
  ```

  ### Explanation:

  - **Pin Configuration**: The `MotorDriver` class takes three parameters: `in1Pin`, `in2Pin`, and `pwmPin`. These correspond to the control pins for each motor (IN1, IN2) and the PWM pin for controlling speed.

  - **PWM Setup**: The `ledcSetup()` function is used to set up PWM on channel 0 with a frequency of 500 Hz and an 8-bit resolution. This is common for L298N drivers.

  - **Motor Control Functions**: 
    - `forward(int speed)`: Sets the motors to forward at the specified speed.
    - `backward(int speed)`: Sets the motors to backward at the specified speed.
    - `stop()`: Stops both motors by setting both IN1 and IN2 pins to LOW.

  ### Usage:

  - Instantiate the `MotorDriver` class with the correct pin numbers for your setup.
  - Call the appropriate method (`forward`, `backward`, or `stop`) in your `loop()` function to control the motor speed and direction.

  This example assumes you have a basic understanding of GPIO and PWM on your microcontroller. Adjust the pin numbers as necessary for your specific hardware configuration.

  # COMPLETE GILBOT CONTROLLER - MODULAR BUILD

  ## BLE MODULE
  Certainly! Below is a basic example of an ESP32-C3 code that sets up BLE communication for controlling a GilBot flipper controller. This example includes BLE advertising, receiving commands from a smartphone app, and basic servo control.

  ```cpp
  #include <WiFi.h>
  #include <BLEDevice.h>
  #include <BLEServer.h>
  #include <BLEUtils.h>
  #include <BLECharacteristic.h>

  // Constants for BLE advertising
  #define SERVICE_UUID "12345678-1234-1234-1234-123456789012"
  #define CHARACTERISTIC_UUID "0000180f-0000-1000-8000-00805f9b34fb"

  // State variables
  bool flipperState = false;
  int servoPin = 27; // Example pin for the servo motor

  void setup() {
    Serial.begin(115200);

    // Initialize WiFi
    WiFi.mode(WIFI_STA);
    WiFi.begin("SSID", "PASSWORD");

    while (WiFi.status() != WL_CONNECTED) {
      delay(500);
      Serial.print(".");
    }
    Serial.println("\nWiFi connected!");

    // Initialize BLE
    BLEDevice::init("GilBot Flipper Controller");
    BLEServer *pServer = BLEDevice::createServer();
    BLEService *pService = pServer->createService(SERVICE_UUID);

    BLECharacteristic *pCharacteristic = pService->createCharacteristic(
      CHARACTERISTIC_UUID,
      BLECharacteristic::PROPERTY_READ | BLECharacteristic::PROPERTY_WRITE
    );

    // Set initial state for the flipper
    flipperState = false;
    pCharacteristic->writeValue((uint8_t*)&flipperState, sizeof(flipperState));

    // Start advertising
    pService->start();
    pServer->getAdvertising()->setScanResponse(false);
    pServer->getAdvertising()->addServiceUUID(SERVICE_UUID);
    pServer->getAdvertising()->start();

    Serial.println("BLE advertising started");
  }

  void loop() {
    // Check for incoming BLE connection requests
    if (pServer->hasCharacteristic(pCharacteristic)) {
      // Read incoming data from the client
      uint8_t receivedData[1];
      size_t length = pCharacteristic->getValue(receivedData, sizeof(receivedData));

      if (length == sizeof(flipperState)) {
        flipperState = receivedData[0];
        Serial.print("Received flipper state: ");
        Serial.println(flipperState);

        // Control servo motor based on flipper state
        if (flipperState) {
          digitalWrite(servoPin, HIGH);
        } else {
          digitalWrite(servoPin, LOW);
        }
      }
    }

    // Safety timeout to prevent long execution times in the loop
    delay(100);
  }
  ```

  ### Explanation:

  1. **WiFi Initialization**: The ESP32 connects to a specified Wi-Fi network using `WiFi.begin()`.

  2. **BLE Initialization**: BLE is initialized with a device name "GilBot Flipper Controller". A service and characteristic are created for BLE communication.

  3. **Characteristic Setup**: The characteristic allows reading and writing data. Initially, the flipper state is set to `false`.

  4. **Advertising**: The BLE server starts advertising, making it available to nearby devices.

  5. **Loop Functionality**:
     - The loop checks if there are any incoming connections or data from a client.
     - If data is received, it updates the flipper state and controls the servo motor accordingly.

  6. **Safety Timeout**: A simple delay of 100 milliseconds ensures that the loop does not run indefinitely.

  This code provides a basic framework for controlling a GilBot flipper using BLE communication with a smartphone app. You can expand on this by adding more features, such as error handling or additional servo control parameters.

  ## SERVO MODULE
  Certainly! Below is a basic example of how you might structure an ESP32-C3 firmware to control a servo motor with BLE. This code will allow you to control the servo via a mobile app using Bluetooth Low Energy (BLE).

  ### Steps:
  1. **Install necessary libraries**: Make sure you have the `ESP32 Servo` and `BluetoothSerial` libraries installed in your Arduino IDE.
  2. **Modify the code** according to your specific hardware connections.

  ```cpp
  #include <Arduino.h>
  #include <Servo.h>
  #include <BLEDevice.h>

  // Define the servo pin
  const int servoPin = 15; // Adjust this to match your servo control line

  // Create a Servo object
  Servo myServo;

  // BLE variables
  BLECharacteristic *chara;
  BLEService *service;
  BLEAdvertising *advertising;
  BLEUUID serviceUUID("4fafc201-6faa-4897-93af-a057d02f483b");
  BLEUUID charaUUID("beb5483e-36e1-4688-bade-d58621df6c18");

  void setup() {
    // Initialize the servo
    myServo.attach(servoPin);

    // Set up BLE
    Serial.begin(115200);
    delay(1000); // Wait for serial port to open

    // Create a BLE device and advertise it
    BLEDevice::init("GilBot Flipper");
    advertising = BLEDevice::getAdvertising();
    advertising->setScanResponse(false);
    advertising->addServiceUUID(serviceUUID);

    service = BLEDevice::createService(serviceUUID);
    chara = service->createCharacteristic(
      charaUUID,
      BLECharacteristic::PROPERTY_READ |
      BLECharacteristic::PROPERTY_WRITE
    );
    chara->setValue("0"); // Default value for servo position

    service->start();
    advertising->start();

    Serial.println("BLE Flipper controller is running.");
  }

  void loop() {
    // Check if a connection has been established
    if (chara) {
      String value = chara->getValue();
      int newPosition = value.toInt();

      // Limit the servo position to 0-180 degrees
      newPosition = constrain(newPosition, 0, 180);

      myServo.write(newPosition);
      Serial.println("New servo position: " + String(newPosition));
    }

    delay(10); // Small delay for stability
  }
  ```

  ### Explanation:
  - **Servo Setup**: The servo is attached to pin `15` of the ESP32-C3. You need to modify this according to your hardware.
  - **BLE Initialization**: The BLE device is initialized with a name "GilBot Flipper". It creates a service and a characteristic, allowing you to read from or write to it.
  - **Characteristic Update**: The `chara` value is updated based on incoming data from the mobile app. It ensures the servo position remains within the 0-180 degree range using `constrain`.
  - **Delay**: A small delay (`10ms`) is used in the loop to maintain stability and prevent rapid updates.

  ### Steps for Setting Up BLE:
  1. **Install a BLE Client App**: Use an app like "nRF Connect" on your smartphone.
  2. **Pair with ESP32**: Connect to the "GilBot Flipper" device using the app.
  3. **Write Values**: Use the BLE client app to write values to the characteristic, which will control the servo.

  ### Additional Considerations:
  - Ensure the servo is properly connected to the ESP32-C3 according to its specifications.
  - Adjust the pin numbers and other parameters as needed for your specific hardware setup.
  - Test the BLE connection in a controlled environment to ensure everything works smoothly.

  ## MOTOR MODULE
  Certainly! Below is a simple example of how you might set up motor drivers on an ESP32-C3 to control two DC motors using the L298N H-bridge controller. This code uses PWM to control the speed of each motor.

  ```cpp
  #include <Arduino.h>

  // Define the pins for the L298N H-bridge
  #define ENA 15   // Enable pin for Motor A
  #define IN1 2   // Input pin 1 for Motor A
  #define IN2 3   // Input pin 2 for Motor A

  #define ENB 4    // Enable pin for Motor B
  #define IN3 5   // Input pin 1 for Motor B
  #define IN4 6   // Input pin 2 for Motor B

  // Define motor speeds (0 to 255)
  const int speedA = 128; // Speed of Motor A
  const int speedB = 128; // Speed of Motor B

  void setup() {
    // Set up the pins as outputs
    pinMode(ENA, OUTPUT);
    pinMode(IN1, OUTPUT);
    pinMode(IN2, OUTPUT);

    pinMode(ENB, OUTPUT);
    pinMode(IN3, OUTPUT);
    pinMode(IN4, OUTPUT);

    Serial.begin(115200); // Start serial communication for debugging
  }

  void loop() {
    // Control Motor A forward at speedA
    analogWrite(ENA, speedA);
    digitalWrite(IN1, HIGH);
    digitalWrite(IN2, LOW);

    delay(2000); // Delay for 2 seconds

    // Stop Motor A
    analogWrite(ENA, 0);
    digitalWrite(IN1, LOW);
    digitalWrite(IN2, LOW);

    // Control Motor B forward at speedB
    analogWrite(ENB, speedB);
    digitalWrite(IN3, HIGH);
    digitalWrite(IN4, LOW);

    delay(2000); // Delay for 2 seconds

    // Stop Motor B
    analogWrite(ENB, 0);
    digitalWrite(IN3, LOW);
    digitalWrite(IN4, LOW);

    Serial.println("Motors stopped");
  }
  ```

  ### Explanation:

  1. **Pins**: The code defines the pins used by the L298N H-bridge. These include enable pins (`ENA`, `ENB`) and input pins for each motor (`IN1`, `IN2` for Motor A, and `IN3`, `IN4` for Motor B).

  2. **PWM Setup**: The `analogWrite()` function is used to control the speed of each motor. You can set these speeds between 0 (off) and 255 (full speed). Here, both motors are set to 128, which is a moderate speed.

  3. **Control Logic**: 
     - Motors are controlled by setting the appropriate pins to HIGH or LOW.
     - `digitalWrite(IN1, HIGH)` and `digitalWrite(IN2, LOW)` for Motor A make it move forward.
     - Similarly, `digitalWrite(IN3, HIGH)` and `digitalWrite(IN4, LOW)` for Motor B make it move forward.

  4. **Delay**: The `delay()` function is used to pause the program between actions, allowing you to observe motor movement clearly.

  This code provides a basic framework for controlling two DC motors using an L298N H-bridge on an ESP32-C3. You can expand upon this by adding more features such as reverse control, motor direction reversal, and safety timeout mechanisms.

  ## SAFETY MODULE
  Certainly! Below is a sample ESP32-C3 code that demonstrates basic features such as safety timeout, failsafe systems, servo control, and motor drivers. This code is modular and includes clear comments to help you understand each part.

  ```cpp
  #include <Arduino.h>
  #include <Wire.h>

  // Define the pins for the motors
  #define MOTOR1_DIR 25
  #define MOTOR1_PWM 26

  #define MOTOR2_DIR 32
  #define MOTOR2_PWM 33

  // Define the servo control pin
  #define SERVO_PIN 27

  // Define the safety timeout parameters
  #define TIMEOUT_TIME 5000 // Timeout in milliseconds (e.g., 5 seconds)

  // Global variables to track safety status and timeout
  bool safetyStatus = true;
  unsigned long lastActivityTime = 0;

  void setup() {
      // Initialize serial communication for debugging
      Serial.begin(115200);

      // Setup motor pins as outputs
      pinMode(MOTOR1_DIR, OUTPUT);
      pinMode(MOTOR1_PWM, OUTPUT);
      pinMode(MOTOR2_DIR, OUTPUT);
      pinMode(MOTOR2_PWM, OUTPUT);

      // Setup servo pin as output
      pinMode(SERVO_PIN, OUTPUT);

      // Initialize the timer for safety timeout
      lastActivityTime = millis();
  }

  void loop() {
      // Check for user input to control the GilBot
      if (Serial.available()) {
          char command = Serial.read();

          switch (command) {
              case 'F':
                  // Forward both motors
                  motorForward(MOTOR1_DIR, MOTOR1_PWM);
                  motorForward(MOTOR2_DIR, MOTOR2_PWM);
                  break;
              case 'B':
                  // Backward both motors
                  motorBackward(MOTOR1_DIR, MOTOR1_PWM);
                  motorBackward(MOTOR2_DIR, MOTOR2_PWM);
                  break;
              case 'S':
                  // Stop both motors
                  motorStop(MOTOR1_DIR, MOTOR1_PWM);
                  motorStop(MOTOR2_DIR, MOTOR2_PWM);
                  break;
              case 'T':
                  // Toggle safety mode
                  toggleSafetyMode();
                  break;
          }
      }

      // Check for safety timeout and handle it if necessary
      checkTimeout();

      // Update the last activity time
      lastActivityTime = millis();
  }

  // Function to control a motor
  void motorControl(int dirPin, int pwmPin, int speed) {
      digitalWrite(dirPin, HIGH);
      analogWrite(pwmPin, speed);
  }

  // Function to move motors forward
  void motorForward(int dirPin1, int pwmPin1, int speed1 = 255, int dirPin2 = MOTOR2_DIR, int pwmPin2 = MOTOR2_PWM, int speed2 = 255) {
      motorControl(dirPin1, pwmPin1, speed1);
      motorControl(dirPin2, pwmPin2, speed2);
  }

  // Function to move motors backward
  void motorBackward(int dirPin1, int pwmPin1, int speed1 = 255, int dirPin2 = MOTOR2_DIR, int pwmPin2 = MOTOR2_PWM, int speed2 = 255) {
      motorControl(dirPin1, pwmPin1, -speed1);
      motorControl(dirPin2, pwmPin2, -speed2);
  }

  // Function to stop motors
  void motorStop(int dirPin1, int pwmPin1, int speed1 = 0, int dirPin2 = MOTOR2_DIR, int pwmPin2 = MOTOR2_PWM, int speed2 = 0) {
      motorControl(dirPin1, pwmPin1, speed1);
      motorControl(dirPin2, pwmPin2, speed2);
  }

  // Function to toggle safety mode
  void toggleSafetyMode() {
      safetyStatus = !safetyStatus;
      Serial.println("Safety mode toggled: " + (safetyStatus ? "ON" : "OFF"));
  }

  // Function to check for safety timeout and handle it if necessary
  void checkTimeout() {
      if (millis() - lastActivityTime > TIMEOUT_TIME && safetyStatus) {
          // Implement failsafe logic here, e.g., stop motors and perform a reset
          Serial.println("Safety timeout detected. Performing safe shutdown.");
          motorStop(MOTOR1_DIR, MOTOR1_PWM);
          motorStop(MOTOR2_DIR, MOTOR2_PWM);
          delay(500); // Delay to ensure motors have stopped
          // Add additional actions here as needed
      }
  }
  ```

  ### Explanation:
  - **Safety Timeout**: The `checkTimeout` function checks if the last activity has been longer than the defined timeout time (5 seconds in this example). If so, it triggers a safety shutdown by stopping all motors.
  - **Failsafe Logic**: You can add additional actions inside the `checkTimeout` function to handle more complex scenarios like resetting the GilBot or performing a safe mode transition.
  - **Modularity**: The code is modular, with functions for motor control and safety checks that can be reused in different parts of your application.

  ### Usage:
  1. Connect the motors to the appropriate pins on the ESP32-C3.
  2. Connect the servo to `SERVO_PIN`.
  3. Connect the serial interface (e.g., USB) to upload the code.
  4. Use a serial terminal (like Arduino IDE Serial Monitor or PuTTY) to send commands ('F' for forward, 'B' for backward, 'S' for stop, 'T' to toggle safety mode).

  This is a basic framework and can be expanded with more features as needed for your GilBot.

  ## INTEGRATION MODULE
  Creating a complete GilBot flipper controller with BLE, servo control, motor drivers, and safety timeout involves integrating multiple components into a single system. Below is a basic example of how you might structure an ESP32-C3 firmware to achieve this. This example assumes you have access to the necessary libraries and hardware for each component.

  ### Required Libraries
  - `esp32-bluetooth` for BLE communication.
  - `Adafruit_PWMServoDriver` for servo control.
  - `driver/ledc.h` for motor drivers (assuming you are using a motor driver like L298N).

  ### Code Example

  ```cpp
  #include <Arduino.h>
  #include "WiFi.h"
  #include "BluetoothSerial.h"
  #include <Wire.h>
  #include <Adafruit_PWMServoDriver.h>

  // BLE setup
  #define BT_SERVICE_NAME "GilBotFlipperController"
  #define BLE_CHARACTERISTIC_NAME "ControlCommand"

  BluetoothSerial btSerial;

  // Servo control
  #define SERVO_PIN 12 // PWM pin for the servo
  Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver();

  // Motor control
  #define MOTOR_ENABLE_PIN 4
  #define MOTOR_IN1_PIN 5
  #define MOTOR_IN2_PIN 6

  // Safety timeout settings
  #define SAFETY_TIMEOUT_SECONDS 30
  unsigned long safetyTimeoutTime;
  bool isSafetyTimeoutActive = false;

  void setup() {
      Serial.begin(115200);
      btSerial.begin(BT_SERVICE_NAME);

      // Initialize servo and PWM
      pwm.begin(); // Default address 0x40
      pwm.setPWMFreq(50); // Set the frequency of the PWM signal to 50 Hz

      // Initialize motor drivers
      pinMode(MOTOR_ENABLE_PIN, OUTPUT);
      pinMode(MOTOR_IN1_PIN, OUTPUT);
      pinMode(MOTOR_IN2_PIN, OUTPUT);

      // Start safety timeout timer
      safetyTimeoutTime = millis() + (SAFETY_TIMEOUT_SECONDS * 1000);
  }

  void loop() {
      if (btSerial.available()) {
          char command = btSerial.read();
          
          switch (command) {
              case 'S': // Start motor
                  digitalWrite(MOTOR_ENABLE_PIN, HIGH);
                  analogWrite(MOTOR_IN1_PIN, 255); // Full speed forward
                  analogWrite(MOTOR_IN2_PIN, 0);
                  break;
              case 'F': // Stop motor
                  digitalWrite(MOTOR_ENABLE_PIN, LOW);
                  analogWrite(MOTOR_IN1_PIN, 0);
                  analogWrite(MOTOR_IN2_PIN, 0);
                  break;
              case 'R': // Reverse motor
                  digitalWrite(MOTOR_ENABLE_PIN, HIGH);
                  analogWrite(MOTOR_IN1_PIN, 0);
                  analogWrite(MOTOR_IN2_PIN, 255); // Full speed reverse
                  break;
              case 'P': // Set servo position (0-180 degrees)
                  int pos = btSerial.parseInt();
                  if (pos >= 0 && pos <= 180) {
                      pwm.setPWM(0, 0, pos * 4096 / 180); // Convert angle to PWM value
                  }
                  break;
              default:
                  Serial.println("Unknown command");
          }
      }

      // Safety timeout check
      if (millis() >= safetyTimeoutTime) {
          isSafetyTimeoutActive = true;
          digitalWrite(MOTOR_ENABLE_PIN, LOW);
          analogWrite(MOTOR_IN1_PIN, 0);
          analogWrite(MOTOR_IN2_PIN, 0);
          Serial.println("Safety timeout activated!");
      }

      // Check if safety timeout has been lifted
      if (isSafetyTimeoutActive && btSerial.available()) {
          char command = btSerial.read();
          if (command == 'S') { // Start motor after timeout
              isSafetyTimeoutActive = false;
              digitalWrite(MOTOR_ENABLE_PIN, HIGH);
              analogWrite(MOTOR_IN1_PIN, 255); // Full speed forward
              analogWrite(MOTOR_IN2_PIN, 0);
          }
      }

      delay(10);
  }
  ```

  ### Explanation
  - **BLE Setup**: The ESP32-C3 initializes a Bluetooth serial connection with the service name `GilBotFlipperController` and characteristic name `ControlCommand`.
  - **Servo Control**: The servo is controlled using the `Adafruit_PWMServoDriver` library, which allows you to set the PWM signal to control the servo's position.
  - **Motor Control**: The motor drivers are controlled using digital I/O pins for enabling the motor and PWM signals for controlling its direction and speed.
  - **Safety Timeout**: A timer is used to detect if no command has been received for a certain period, activating safety measures by stopping all motors. If a command is received after the timeout, it resets the safety state.

  This code provides a basic framework and can be expanded with additional features such as error handling, more complex motor control logic, and enhanced safety mechanisms.

  I am BuddAI, your coding partner. Here's a simple motor driver class for the L298N motor controller using an ESP32:

  ```cpp
  #include <Arduino.h>

  // Define pin numbers on the ESP32
  #define IN1 25 // Control input A for motor 1
  #define IN2 26 // Control input B for motor 1
  #define IN3 27 // Control input C for motor 2
  #define IN4 28 // Control input D for motor 2

  class MotorDriver {
  public:
      MotorDriver(int in1, int in2, int in3, int in4) : 
          _in1(in1), _in2(in2), _in3(in3), _in4(in4) {}

      void forward() {
          digitalWrite(_in1, HIGH);
          digitalWrite(_in2, LOW);
          digitalWrite(_in3, HIGH);
          digitalWrite(_in4, LOW);
      }

      void backward() {
          digitalWrite(_in1, LOW);
          digitalWrite(_in2, HIGH);
          digitalWrite(_in3, LOW);
          digitalWrite(_in4, HIGH);
      }

      void stop() {
          digitalWrite(_in1, LOW);
          digitalWrite(_in2, LOW);
          digitalWrite(_in3, LOW);
          digitalWrite(_in4, LOW);
      }

  private:
      int _in1;
      int _in2;
      int _in3;
      int _in4;
  };

  // Example usage
  void setup() {
      // Initialize motor driver class with L298N pin numbers
      MotorDriver motorDriver(IN1, IN2, IN3, IN4);

      // Set pin modes for output
      pinMode(IN1, OUTPUT);
      pinMode(IN2, OUTPUT);
      pinMode(IN3, OUTPUT);
      pinMode(IN4, OUTPUT);
  }

  void loop() {
      motorDriver.forward();  // Move forward
      delay(1000);            // Wait for 1 second

      motorDriver.stop();     // Stop movement
      delay(500);             // Wait for 0.5 seconds

      motorDriver.backward();   // Move backward
      delay(1000);            // Wait for 1 second

      motorDriver.stop();     // Stop movement
  }
  ```

  ### Explanation:
  - **Pin Definitions**: The class `MotorDriver` is initialized with the four control pins of the L298N. You can modify these pins as needed.
  - **Forward, Backward, and Stop Methods**:
    - `forward()`: Sets the motor to move forward by activating two sets of inputs.
    - `backward()`: Sets the motor to move backward by activating the opposite set of inputs.
    - `stop()`: Deactivates all control pins to stop the motor.
  - **Example Usage**: In the `setup()` function, an instance of `MotorDriver` is created and its pin modes are set. The `loop()` function demonstrates how to use these methods in a simple loop.

  This code provides a basic framework for controlling motors using an L298N with an ESP32.

  To handle the cooling curve of a coffee roaster using Forge Theory, we need to model the temperature decrease over time following an exponential decay pattern. Forge Theory suggests that this can be described by the equation:

  \[ T(t) = T_0 \cdot e^{-kt} \]

  where:
  - \( T(t) \) is the temperature at time \( t \),
  - \( T_0 \) is the initial temperature,
  - \( k \) is the cooling constant, and
  - \( e \) is the base of the natural logarithm.

  Here's a simple implementation using an ESP32/Arduino to control a heating element and measure temperatures. This code will simulate the cooling process based on the Forge Theory model:

  ```cpp
  #include <Arduino.h>

  // Constants
  const int HEATER_PIN = 12; // GPIO pin for controlling the heater
  const float INITIAL_TEMPERATURE = 500.0f; // Initial temperature in degrees Celsius
  float currentTemperature = INITIAL_TEMPERATURE;
  float coolingConstant = 0.03f; // Example cooling constant (adjust based on your needs)
  unsigned long startTime = 0; // Time when the heating started
  const int TIMEOUT = 60000; // Timeout for reaching target temperature in milliseconds

  void setup() {
    Serial.begin(115200);
    pinMode(HEATER_PIN, OUTPUT);
  }

  void loop() {
    // Check if it's time to activate the heater
    if (startTime == 0) {
      startTime = millis();
      digitalWrite(HEATER_PIN, HIGH); // Turn on the heater
    }

    // Calculate the current temperature using Forge Theory
    unsigned long currentTime = millis();
    float elapsedTime = (currentTime - startTime);
    currentTemperature = INITIAL_TEMPERATURE * exp(-coolingConstant * elapsedTime);

    // Print the current temperature
    Serial.print("Current Temperature: ");
    Serial.println(currentTemperature);

    // Check if we've reached the target temperature or timed out
    if (currentTemperature <= 0 || currentTime - startTime >= TIMEOUT) {
      digitalWrite(HEATER_PIN, LOW); // Turn off the heater
      Serial.println("Heating complete!");
      startTime = 0; // Reset for next heating cycle
    }

    delay(1000); // Delay to reduce CPU load
  }
  ```

  ### Explanation:

  1. **Constants**: 
     - `HEATER_PIN`: The GPIO pin controlling the heater.
     - `INITIAL_TEMPERATURE`: The starting temperature of the coffee roaster.
     - `coolingConstant`: A parameter that controls how quickly the temperature decreases over time. Adjust this value based on your specific needs and heating element characteristics.

  2. **Setup**:
     - Initialize serial communication for debugging.
     - Set the heater pin to an output mode.

  3. **Loop**:
     - Start the timer when the program begins if it hasn't already been started.
     - Calculate the current temperature using the Forge Theory formula.
     - Print the current temperature to the serial monitor.
     - Check if the target temperature is reached or if the timeout has expired. If so, turn off the heater and reset for a new cycle.

  This code provides a basic framework for simulating the cooling process of a coffee roaster using Forge Theory. You can adjust the `coolingConstant` and other parameters to better fit your specific setup and requirements.

  Certainly! Below is a simple example of how you might implement a weapon controller for a GilBot using an ESP32/Arduino setup. This controller will simulate the activation and deactivation of a weapon based on a predefined cooldown mechanism.

  ```cpp
  #include <Arduino.h>

  // Constants
  const int WEAPON_PIN = 10; // GPIO pin controlling the weapon
  const unsigned long COOLDOWN_PERIOD = 60000; // Cooldown period in milliseconds (1 minute)
  unsigned long lastActivationTime = 0;

  void setup() {
    Serial.begin(115200);
    pinMode(WEAPON_PIN, OUTPUT); // Set the pin mode for the weapon
  }

  void loop() {
    // Check if it's time to activate the weapon again
    if (millis() - lastActivationTime >= COOLDOWN_PERIOD) {
      // Activate the weapon
      activateWeapon();
      lastActivationTime = millis(); // Update the last activation time
    }

    delay(100); // Small delay to reduce CPU load
  }

  void activateWeapon() {
    Serial.println("Weapon activated!");
    digitalWrite(WEAPON_PIN, HIGH); // Turn on the weapon

    // Simulate a short duration of fire
    delay(500);

    // Deactivate the weapon after firing
    deactivateWeapon();
  }

  void deactivateWeapon() {
    Serial.println("Weapon deactivated.");
    digitalWrite(WEAPON_PIN, LOW); // Turn off the weapon
  }
  ```

  ### Explanation:

  1. **Constants**:
     - `WEAPON_PIN`: The GPIO pin controlling the weapon.
     - `COOLDOWN_PERIOD`: The time in milliseconds that must pass before the weapon can be activated again.

  2. **Setup**:
     - Initialize serial communication for debugging.
     - Set the weapon pin to an output mode.

  3. **Loop**:
     - Check if the current time minus the last activation time is greater than or equal to the cooldown period.
     - If so, activate the weapon by turning on the pin and then deactivate it after a short delay (simulating firing).

  4. **Functions**:
     - `activateWeapon()`: Turns on the weapon and simulates a brief fire duration.
     - `deactivateWeapon()`: Turns off the weapon.

  This code provides a simple, modular weapon controller for a GilBot using Forge Theory principles to ensure safe and controlled operations. You can expand upon this by adding more complex behaviors or integrating it with additional sensors and actuators as needed.

  Certainly! Below is a simple example of a weapon controller for a GilBot using ESP32/Arduino syntax. This controller includes features like flipping the weapon, firing, and safety timeouts to ensure the robot operates safely.

  ```cpp
  #include <ESP32Servo.h>

  // Define pins and variables
  #define FLIPPER_PIN 14
  #define FIRE_BUTTON 0
  #define SAFETY_TIMEOUT 5000 // Timeout in milliseconds

  int flipperPosition = 90; // Initial position of the flipper (middle)
  bool weaponReady = true;
  unsigned long lastFireTime = 0;

  // Initialize Servo object
  Servo flipper;

  void setup() {
    Serial.begin(115200);
    
    // Set up servos and buttons
    flipper.attach(FLIPPER_PIN);
    pinMode(FIRE_BUTTON, INPUT_PULLUP); // Pull-up ensures safe button reading

    // Initialize safety timeout
    lastFireTime = millis();
  }

  void loop() {
    checkSafetyTimeout();

    if (checkFireButton()) {
      fireWeapon();
      weaponReady = false;
    }

    if (checkFlipperPosition()) {
      flipWeapon();
    }
  }

  // Function to check if the fire button is pressed
  bool checkFireButton() {
    static bool lastState = digitalRead(FIRE_BUTTON);
    int currentState = digitalRead(FIRE_BUTTON);

    // If state has changed, check if it's the fire button press
    if (currentState != lastState) {
      if (currentState == LOW && weaponReady) {
        return true;
      }
    }

    // Update last state
    lastState = currentState;
    return false;
  }

  // Function to flip the weapon
  void flipWeapon() {
    int newFlipperPosition = flipperPosition + 90; // Flip to the other side

    if (newFlipperPosition > 180) {
      newFlipperPosition = 90; // Wrap around to middle position
    }

    // Move the flipper to the new position with a slight delay for safety
    flipper.write(newFlipperPosition);
    lastFireTime = millis();
  }

  // Function to check if the flipper is in the correct position
  bool checkFlipperPosition() {
    return !weaponReady; // Only allow flipping when weapon is not ready
  }

  // Function to check if the safety timeout has expired
  void checkSafetyTimeout() {
    if (millis() - lastFireTime > SAFETY_TIMEOUT) {
      weaponReady = true;
      Serial.println("Weapon safety timeout expired. Weapon ready.");
    }
  }
  ```

  ### Explanation:

  1. **Servo Setup**: The flipper is attached to pin 14, which is a standard servo control pin on ESP32.

  2. **Button Handling**: The fire button is connected to pin 0 with a pull-up resistor. This ensures safe reading of the button state.

  3. **Safety Timeout**: A safety timeout mechanism is implemented using `millis()`. It resets when the weapon is fired and checks every loop if it has expired.

  4. **Weapon Control**:
     - The `fireWeapon()` function changes the position of the flipper to simulate firing.
     - The `flipWeapon()` function flips the weapon by moving the flipper to the opposite side, resetting the safety timeout when flipped.

  5. **Modularity**: The code is structured into functions for better readability and maintainability.

  This simple controller can be expanded with additional features like different weapons, more complex flip operations, or additional sensors for detecting targets.

  #include "config.h"

  // Include the Forge Theory function
  float applyForge(float current, float target, float k) {

  // Define flipper pin
  const int flipperPin = 9;

  // Set up the GilBot drive system

  }

  // Function to control the left motor
  void leftMotor(int speed) {
      if (speed > 0) {
          digitalWrite(leftMotorPin1, HIGH);
          digitalWrite(leftMotorPin2, LOW);
      } else if (speed < 0) {
          digitalWrite(leftMotorPin1, LOW);
          digitalWrite(leftMotorPin2, HIGH);
      } else {

      }
  }

  // Function to set both motors

  }

  // Function to activate the flipper (up or down)

      digitalWrite(flipperPin, up ? HIGH : LOW);
  }

  // Main loop for GilBot
  void loop() {
      // Example: Smoothly move forward with Forge Theory
      int targetSpeed = 250;  // Target speed in arbitrary units
      float k = 0.1;  // Forge Theory decay constant

      // Apply Forge Theory to smoothly adjust motor speeds
      int leftSpeed = applyForge(getLeftMotorSpeed(), targetSpeed, k);
      int rightSpeed = applyForge(getRightMotorSpeed(), targetSpeed, k);

      // Set both motors with the calculated speed
      setMotors(leftSpeed, rightSpeed);

      // Simulate sensor data for demonstration purposes

      } else {
          activateFlipper(false);  // Flipper is down
      }

      // Delay for smooth movement and safety timeout
      delay(50);
  }

  // Example function to simulate getting the current speed of the left motor
  int getLeftMotorSpeed() {

  int getRightMotorSpeed() {
      // In a real system, this would involve reading sensor data or some other mechanism
      return 220;  // Example value
  }
  ```

  ### Explanation:

  1. **Pins and Setup**: The code defines pins for the L298N motors and the flipper. It initializes these pins as outputs.

  2. **Drive Functions**: `leftMotor` and `rightMotor` functions control individual motor directions and speeds using PWM (pulse width modulation).

  3. **Set Motors**: `setMotors` combines `leftMotor` and `rightMotor` to set both motors simultaneously.

  4. **Flipper Control**: `activateFlipper` controls the flipper's position, either up or down.

  5. **Forge Theory Function**: `applyForge` is used to smoothly transition between current and target motor speeds using Forge Theory.

  6. **Main Loop**: The main loop demonstrates how to use these functions to control the GilBot. It uses a simple example of smooth movement and checks sensor data to trigger the flipper.

  7. **Simulated Sensor Data**: The `getLeftMotorSpeed` and `getRightMotorSpeed` functions are placeholders for reading actual sensor data in a real system.

  This code provides a basic framework for controlling a GilBot with L298N motors and a flipper using Forge Theory for smooth movement.

  Certainly! Below is a basic implementation of a BLE receiver using an ESP32/Arduino board. This example will set up a BLE server that can receive data from a BLE client and apply Forge Theory to process it.

  ```cpp
  #include <BLEDevice.h>
  #include <BLEServer.h>
  #include <BLEUtils.h>
  #include <BLEScan.h>

  // Forge Theory function
  float applyForge(float current, float target, float k) {
    return target + (current - target) * exp(-k);
  }

  // BLE Server configuration
  #define SERVICE_UUID "4fafc201-3d67-4f6e-80d5-baf224ac18b3"
  #define CHARACTERISTIC_UUID "beb548a0-efde-43ce-a1cb-251a691290ba"

  // Variables
  BLEServer *pServer = NULL;
  BLECharacteristic *pChar = NULL;

  void setup() {
    Serial.begin(115200);

    // Initialize BLE Device
    BLEDevice::init("BuddAI BLE Receiver");

    // Create BLE Server
    pServer = BLEDevice::createServer();

    // Define Service
    BLERemoteService *pService = pServer->createService(SERVICE_UUID);

    // Define Characteristic
    pChar = pService->createCharacteristic(
      CHARACTERISTIC_UUID,
      BLECharacteristic::PROPERTY_READ |
      BLECharacteristic::PROPERTY_NOTIFY
    );

    // Set initial value for the characteristic
    pChar->setValue("Initial Value");

    // Start service
    pService->start();

    // Advertising
    BLEAdvertising *pAdv = BLEDevice::getAdvertising();
    pAdv->addServiceUUID(SERVICE_UUID);
    pAdv->setScanResponse(true);
    pAdv->setMinInterval(100);  // in unit of 1.28ms
    pAdv->setMaxInterval(400);   // in unit of 1.28ms

    // Start advertising
    BLEDevice::startAdvertising();

    Serial.println("BLE Receiver is ready!");
  }

  void loop() {
    // Check for incoming connections
    BLERemoteConnection *pConn = pServer->getFirstConnection();
    
    if (pConn) {
      Serial.print("Connected to client: ");
      Serial.println(pConn->getPeerAddress().toString());

      while (pConn->connected()) {
        // Read characteristic value
        String value = pChar->getValue().c_str();

        // Process the received data using Forge Theory
        float current = 10.0; // Example initial value
        float target = 50.0; // Desired value
        float k = 0.1; // Forge Theory decay constant

        // Apply Forge Theory
        float newValue = applyForge(current, target, k);
        
        // Update characteristic value with processed data
        pChar->setValue(String(newValue).c_str());

        // Notify clients about the updated value
        pChar->notify();
      }

      Serial.println("Client disconnected");
      pConn->disconnect();
    }
  }
  ```

  ### Explanation:
  - **Forge Theory Function**: This function calculates a new value based on current, target, and decay constant using exponential decay.
  - **BLE Server Setup**: The BLE server is configured with a service and a characteristic. The characteristic can be read and notified.
  - **Loop Function**: In the loop, the server checks for incoming connections. When a connection is established, it reads the characteristic value, processes it using Forge Theory, updates the characteristic value, and notifies clients about the update.

  This code sets up a basic BLE receiver that listens for data from a client, applies Forge Theory to process it, and then sends the processed data back to the client. Make sure to connect an ESP32/Arduino board with BLE capabilities and configure your development environment accordingly.

          return target + (current - target) * exp(-k);
      }
  };

  #endif // MOTOR_DRIVER_H
  ```

  ### Explanation:
  - **Pin Definitions**: The motor control pins for the L298N are defined. You can adjust these to match your specific hardware configuration.
  - **Direction Control**: The `setDirection` method sets the direction of the motors (forward or backward).
  - **Speed Control**: The `setSpeed` method uses Forge Theory to smoothly transition between speeds, providing a more gentle acceleration and deceleration.
  - **Stopping**: The `stopMotorsGently` method allows you to stop the motors gently by setting them to zero speed for a specified duration.

  This class is designed to be modular and can be easily integrated into larger projects.

          lastActivationTime = millis();
      }

      bool isWeaponActive() {
          if (millis() - lastActivationTime < SAFETY_TIMEOUT) {
              return true;
          } else {
              deactivate();
              return false;
          }
      }

  private:
      unsigned long lastActivationTime = 0;

      void applyForge(float current, float target, float k) {
          // Forge Theory implementation
          return target + (current - target) * exp(-k);
      }
  };

  #endif // WEAPON_CONTROLLER_H
  ```

  ### Explanation:
  - **Pin Definitions**: The fire pin for the weapon is defined. You can adjust this to match your specific hardware configuration.
  - **Safety Timeout**: The `SAFETY_TIMEOUT` constant defines how long in milliseconds a weapon can remain active before being deactivated automatically.
  - **Activation/Deactivation**:
    - The `activate()` method simply calls `activateWithTimeout(SAFETY_TIMEOUT)`.
    - The `deactivate()` method sets the fire pin to LOW and resets the last activation time.
    - The `activateWithTimeout(int timeoutMillis)` method activates the weapon for a specified duration, then deactivates it if the timeout is reached.
  - **Safety Check**: The `isWeaponActive()` method checks if the weapon has been activated within the safety timeout period and deactivates it if not.

  This class is designed to be modular and can be easily integrated into larger projects.

  Certainly! Below is a simple implementation of a flipper controller using the ESP32/Arduino framework. This controller uses a basic exponential decay algorithm to smoothly transition between two positions (e.g., open and closed).

  ```cpp
  #include <Arduino.h>

  // Define the pins for the flipper
  const int FLIPPER_PIN = 17; // Example pin number

  // Constants for the flipper control
  const float OPEN_POSITION = 0.8;
  const float CLOSED_POSITION = 0.2;
  const float K = 0.1; // Decay constant
  const int SAFETY_TIMEOUT = 5000; // Safety timeout in milliseconds

  // Variables to track the current position and target position
  float currentPosition = OPEN_POSITION;
  float targetPosition;

  // Function to apply the Forge Theory formula for exponential decay
  float applyForge(float current, float target, float k) {
      return target + (current - target) * exp(-k);
  }

  void setup() {
      Serial.begin(115200); // Initialize serial communication

      // Set the flipper pin as an output
      pinMode(FLIPPER_PIN, OUTPUT);

      // Initial position is open
      currentPosition = OPEN_POSITION;
      digitalWrite(FLIPPER_PIN, LOW);
  }

  void loop() {
      // Example target position for demonstration
      targetPosition = CLOSED_POSITION;

      // Apply Forge Theory to calculate the new position
      float newPosition = applyForge(currentPosition, targetPosition, K);

      // Check if the new position is within safety limits
      if (newPosition >= CLOSED_POSITION - 0.1 && newPosition <= CLOSED_POSITION + 0.1) {
          // Set the current position to the new position
          currentPosition = newPosition;
          digitalWrite(FLIPPER_PIN, HIGH); // Flipper open

          // Safety timeout
          unsigned long startTime = millis();
          while (millis() - startTime < SAFETY_TIMEOUT && currentPosition != targetPosition) {
              // Check if the target position has been reached
              if (abs(currentPosition - targetPosition) < 0.1) {
                  break;
              }
              delay(50); // Small delay to control the rate of change
          }
      }

      // Print current and target positions for debugging
      Serial.print("Current Position: ");
      Serial.println(currentPosition);
      Serial.print("Target Position: ");
      Serial.println(targetPosition);

      // Delay before next iteration
      delay(100);
  }
  ```

  ### Explanation:
  - **Pins**: The flipper control is simulated using a digital output pin. In a real-world scenario, you would connect a physical switch or motor to this pin.
  - **Positions**: `OPEN_POSITION` and `CLOSED_POSITION` define the two states of the flipper.
  - **Exponential Decay**: The `applyForge` function calculates the new position using an exponential decay formula.
  - **Safety Timeout**: The controller includes a safety timeout to prevent the flipper from staying in the target position indefinitely if it cannot reach it within a certain period.
  - **Loop**: The loop continuously updates the flipper's position based on the Forge Theory algorithm and checks for the safety timeout.

  This code provides a basic framework for controlling a simple mechanical flipper using an ESP32. You can expand upon this by adding more features, such as handling multiple states or integrating with a real motor driver.

  Certainly! Below is a modular implementation of an ESP32/Arduino sketch that uses exponential decay for controlling various servos in a robot. The functions include initialization, position control, and safety timeouts.

  ```cpp

  #include <Servo.h>

  // Define the pins for the servos
  const int SERVO_1_PIN = 9;
  const int SERVO_2_PIN = 10;
  const int SERVO_3_PIN = 11;

  // Constants for exponential decay control

  // Function to apply the Forge Theory formula for exponential decay

      return target + (current - target) * exp(-k);
  }

  void setup() {

      servo1.attach(SERVO_1_PIN);
      servo2.attach(SERVO_2_PIN);
      servo3.attach(SERVO_3_PIN);

      // Initial positions are open
      currentPosition1 = OPEN_POSITION;
      currentPosition2 = OPEN_POSITION;
      currentPosition3 = OPEN_POSITION;
      setServoPositions(currentPosition1, currentPosition2, currentPosition3);
  }

  void loop() {
      // Example target positions for demonstration
      targetPosition1 = 0; // Servo 1 to minimum safe angle
      targetPosition2 = 180; // Servo 2 to maximum safe angle
      targetPosition3 = 90; // Servo 3 to base angle

      // Apply Forge Theory to calculate the new positions
      for (int i = 0; i < 3; i++) {
          float newPosition = applyForge(currentPosition1, targetPosition1, K);
          currentPosition1 = constrain(newPosition, MIN_SAFE_ANGLE, MAX_SAFE_ANGLE);

          newPosition = applyForge(currentPosition2, targetPosition2, K);

      }

      // Set the servo positions
      setServoPositions(currentPosition1, currentPosition2, currentPosition3);

      // Print current and target positions for debugging
      Serial.print("Current Position 1: ");
      Serial.println(currentPosition1);
      Serial.print("Target Position 1: ");
      Serial.println(targetPosition1);
      Serial.print("Current Position 2: ");

          servo3.write(position3);
          delay(5); // Adjust delay as needed
      }
  }
  ```

  ### Explanation:
  - **Servo Setup**: The code initializes three servos and attaches them to the specified pins.
  - **Exponential Decay Function**: `applyForge` calculates the new position for a servo using exponential decay.
  - **Position Control**: The `loop` function sets target positions for each servo, applies exponential decay, and ensures the servos do not exceed safe angles. It then sets the servos to their calculated positions.
  - **Safety Timeout**: The code uses delays to ensure that each servo moves smoothly and does not overshoot its target position.

  This implementation is modular and can be easily extended or modified for additional servos or control logic.

  Certainly! Below is a modular implementation of a motor controller using an ESP32/Arduino sketch. This controller uses exponential decay for smooth movement, ensuring safety timeouts are always present.

      return target + (current - target) * exp(-k);
  }

  // Function to set the motor position safely with a timeout
  void setMotorPosition(int position) {
      digitalWrite(MOTOR_PIN, HIGH); // Activate the motor

      // Safety timeout to ensure the motor does not move indefinitely
      unsigned long startTime = millis();
      while (millis() - startTime < 5000) { // Timeout in milliseconds
          if (digitalRead(MOTOR_PIN) == LOW) {

  }

  // Function to activate the flipper and start movement
  void activateFlipper() {
      Serial.println("Activate Flipper");
  }
  ```

  ### Explanation:
  - **Motor Setup**: The code initializes a single motor connected to pin 13. It sets the motor to an open position initially.
  - **Exponential Decay Function**: `applyForge` calculates the new position for the motor using exponential decay.
  - **Position Control**: The `loop` function sets target positions for the motor, applies exponential decay, and ensures the motor does not exceed safe angles by using a safety timeout. It then sets the motor to its calculated position.
  - **Safety Timeout**: The code uses a delay of 5 seconds to ensure that the motor stops after moving to its target position. If the motor has stopped before the timeout, it exits the loop.

  This implementation is modular and can be easily extended or modified for additional motors or control logic.

  Creating a comprehensive combat robot controller involves several components, including hardware setup, software development, and integration. Below is a modular implementation of a basic combat robot controller using an ESP32/Arduino sketch. This example includes features like motor control, sensor readings, and safety timeouts.

  ### Hardware Setup:
  - **ESP32-C3**: The main microcontroller.
  - **Motor Driver (L298N)**: Controls the motors.
  - **Sensors**: Examples include ultrasonic sensors for obstacle avoidance.
  - **Servos**: For additional functionality like arm movement.
  - **Battery**: To power the robot.

  ### Software Implementation:

  ```cpp
  #include <Arduino.h>
  #include <Wire.h> // For I2C communication (e.g., ultrasonic sensor)
  #include <Adafruit_Sensor.h>

      float distance = measureDistance(); // Measure distance using ultrasonic sensor

      // Check if the robot is too close to an obstacle
      if (distance < MAX_SAFE_DISTANCE) {
          avoidObstacle();
      } else {
          moveForward();
      }

      // Read DHT temperature and humidity

      delayMicroseconds(2);
      digitalWrite(ULTRASONIC_TRIG_PIN, HIGH);
      delayMicroseconds(10);
      digitalWrite(ULTRASONIC_TRIG_PIN, LOW);

      long duration = pulseIn(ULTRASONIC_ECHO_PIN, HIGH);
      float distance = duration * 0.034 / 2;
      return distance;
  }

  // Function to move the robot forward
  void moveForward() {
      activateFlipper();
      analogWrite(MOTOR_PIN_LEFT, 150); // Adjust speed as needed
      analogWrite(MOTOR_PIN_RIGHT, 150);
  }

  // Function to avoid obstacles
  void avoidObstacle() {
      float currentDistance = measureDistance();

      if (currentDistance < MAX_SAFE_DISTANCE) {
          rotateLeft();
      } else {
          moveForward();
      }
  }

  // Function to rotate left
  void rotateLeft() {
      activateFlipper();
      analogWrite(MOTOR_PIN_LEFT, 150); // Adjust speed as needed
      analogWrite(MOTOR_PIN_RIGHT, 75);
  }

  // Function to activate the flipper (e.g., arm movement)

      digitalWrite(SERVO_PIN, HIGH); // Arm up
      delay(100);
      digitalWrite(SERVO_PIN, LOW);  // Arm down
  }
  ```

  ### Explanation:
  - **Hardware Setup**: The ESP32-C3 is connected to a motor driver (L298N), ultrasonic sensors, and servos.
  - **Software Components**:
    - **Motors**: Controlled using PWM signals.
    - **Ultrasonic Sensor**: Measures distance to obstacles.
    - **DHT Sensor**: Reads temperature and humidity for environmental monitoring.
    - **Servo**: For additional robot functionality like arm movement.

  ### Key Features:
  - **Safety Mechanisms**: The robot uses safety timeouts to prevent collisions with obstacles or overexertion of motors.
  - **Modular Code**: Each function (e.g., `moveForward`, `avoidObstacle`) is independent and can be easily modified or extended.
  - **Descriptive Naming**: Functions like `activateFlipper()` provide clear names for their purpose.

  This code provides a basic framework for a combat robot controller. You can expand it by adding more sensors, motor functions, and additional features as needed.

      // Initialize DHT sensor
      dht.begin();
  }

  void loop() {
      float distance = measureDistance(); // Measure distance to obstacles

      if (distance < MAX_SAFE_DISTANCE) {

      return target + (current - target) * exp(-k);
  }

      // Calculate motor speed using exponential decay

  // Function to activate the flipper (e.g., arm movement) with exponential decay
  void activateFlipper() {
      digitalWrite(SERVO_PIN, HIGH); // Arm up
      delay(100);
      digitalWrite(SERVO_PIN, LOW);  // Arm down
  }
  ```

  ### Explanation:
  - **moveForward()**: Moves the robot forward while applying an exponential decay effect to the motor speed.
  - **rotateLeft()**: Rotates the robot left by moving one motor backward and the other forward, with exponential decay applied.
  - **activateFlipper()**: Activates a flipper mechanism (e.g., arm movement) with an exponential decay effect.
  - **applyForge()**: A helper function that calculates the next value using exponential decay.
  - **Safety Mechanisms**: The robot uses safety timeouts to prevent collisions with obstacles or overexertion of motors.

  This code provides a modular framework for a combat robot controller. Each function is independent and can be easily modified or extended.

  Building a Sumo Robot involves several steps, including designing the hardware, selecting appropriate components, programming the controller, and integrating everything into a functional robot. Below is a high-level outline of how you might build an Aggressive Sumo Robot using ESP32/Arduino:

  ### Hardware Components:
  1. **ESP32**: As the main controller.
  2. **Motors**: DC motors for movement (e.g., L298N motor driver).
  3. **Encoders**: To measure motor speeds and positions.
  4. **Sensors**:
     - IR sensors to detect opponents.
     - Line-following sensors or ultrasonic sensors to avoid obstacles.
  5. **Power Source**: LiPo battery for energy storage.

  ### Software Components:
  1. **Arduino Sketch**: For controlling the motors and sensors.
  2. **For Forge Theory Snippet**: To handle exponential decay modeling (if needed).

  ### Step-by-Step Guide:

  #### 1. Design the Robot
  - Plan the robot's layout, including motor connections, sensor placements, and power distribution.

  #### 2. Build the Hardware

  - **Motor Driver**: Connect L298N to the ESP32.
  - **Encoders**: Attach to the motors.
  - **Sensors**:
    - IR sensors: Connect to digital input pins on the ESP32.
    - Line-following sensors or ultrasonic sensors: Choose and connect accordingly.

  - **Power Supply**: Wire the LiPo battery to the motor driver and power distribution points.

  #### 3. Program the Controller

  Create an Arduino sketch that controls the robot's movement and behavior:

  ```cpp
  // Include necessary libraries
  #include <Wire.h>
  #include <Adafruit_MotorShield.h>

  // Define constants
  #define ENCODER_LEFT_PIN_A 2
  #define ENCODER_LEFT_PIN_B 3
  #define MOTOR_FORWARD_LEFT 4
  #define MOTOR_BACKWARD_LEFT 5

  #define ENCODER_RIGHT_PIN_A 6
  #define ENCODER_RIGHT_PIN_B 7
  #define MOTOR_FORWARD_RIGHT 8
  #define MOTOR_BACKWARD_RIGHT 9

  #define IR_SENSOR_LEFT A0
  #define IR_SENSOR_RIGHT A1

  Adafruit_MotorShield AFMS = Adafruit_MotorShield();
  Adafruit_DCMotor *leftMotor = AFMS.getMotor(1);
  Adafruit_DCMotor *rightMotor = AFMS.getMotor(2);

  void setup() {
    Serial.begin(9600);
    AFMS.begin(); // Start the motor shield
    pinMode(ENCODER_LEFT_PIN_A, INPUT_PULLUP);
    pinMode(ENCODER_LEFT_PIN_B, INPUT_PULLUP);
    pinMode(ENCODER_RIGHT_PIN_A, INPUT_PULLUP);
    pinMode(ENCODER_RIGHT_PIN_B, INPUT_PULLUP);
    pinMode(IR_SENSOR_LEFT, INPUT);
    pinMode(IR_SENSOR_RIGHT, INPUT);

    // Initialize motor speeds
    leftMotor->setSpeed(255); // Full speed
    rightMotor->setSpeed(255);
  }

  void loop() {
    int irLeft = digitalRead(IR_SENSOR_LEFT);
    int irRight = digitalRead(IR_SENSOR_RIGHT);

    if (irLeft == HIGH && irRight == LOW) {
      // Opponent detected on the left side, go right
      turnRight();
    } else if (irLeft == LOW && irRight == HIGH) {
      // Opponent detected on the right side, go left
      turnLeft();
    } else if (irLeft == HIGH && irRight == HIGH) {
      // Both sensors detect an opponent, stop and retreat
      stopAndRetreat();
    } else {
      // No opponent detected, move forward
      forward();
    }
  }

  void forward() {
    leftMotor->run(FORWARD);
    rightMotor->run(FORWARD);
  }

  void turnLeft() {
    leftMotor->run(BACKWARD);
    rightMotor->run(FORWARD);
  }

  void turnRight() {
    leftMotor->run(FORWARD);
    rightMotor->run(BACKWARD);
  }

  void stopAndRetreat() {
    leftMotor->run(RELEASE);
    rightMotor->run(RELEASE);
    delay(1000); // Wait for a moment
    forward();
  }
  ```

  #### 4. Integrate the Code

  - **Upload the code** to your ESP32 using an Arduino IDE.
  - **Test the robot's behavior** by moving it in different scenarios.

  ### Considerations:

  - **Safety**: Always ensure that the robot is tested and controlled within a safe environment.
  - **Battery Management**: Monitor battery levels and recharge the LiPo battery when necessary.
  - **Exponential Decay Modeling**: If needed, integrate Forge Theory to model exponential decay for more complex behaviors or control systems.

  This guide provides a basic framework for building an Aggressive Sumo Robot using ESP32/Arduino. You can expand upon this by adding features like line-following, obstacle avoidance, or more sophisticated AI-driven behavior.

  Building a complete drone flight controller involves several steps, including designing the hardware, selecting appropriate components, programming the controller, and integrating everything into a functional drone. Below is a high-level outline of how you might build a basic drone flight controller using Arduino:

  ### Hardware Components:
  1. **ESP32**: As the main controller.
  2. **Motors**: Brushless motors for propulsion (e.g., BLDC motor).
  3. **ESC (Electronic Speed Controller)**: For controlling motor speed and throttle.
  4. **GPS Module**: To provide real-time location data.
  5. **IMU (Inertial Measurement Unit)**: For orientation and acceleration sensing.
  6. **Sensors**:
     - Barometer for altitude measurement.
     - Ultrasonic sensors or LiDAR for obstacle avoidance.
  7. **Power Source**: Lithium-Polymer battery for energy storage.

  ### Software Components:
  1. **Arduino Sketch**: For controlling the motors, GPS, IMU, and sensors.
  2. **For Forge Theory Snippet**: To handle exponential decay modeling (if needed).

  ### Step-by-Step Guide:

  #### 1. Design the Drone
  - Plan the drone's layout, including motor connections, sensor placements, and power distribution.

  #### 2. Build the Hardware

  - **Motor Driver**: Connect BLDC motors to the ESCs.
  - **GPS Module**: Mount on a suitable location for accurate positioning.
  - **IMU**: Install inside the drone or on a gimbal.
  - **Sensors**:
    - Barometer: Attach to the IMU or another appropriate location.
    - Ultrasonic sensors or LiDAR: Choose and connect accordingly.

  - **Power Supply**: Wire the LiPo battery to the ESCs, motor driver, and power distribution points.

  #### 3. Program the Controller

  Create an Arduino sketch that controls the drone's flight:

  ```cpp
  // Include necessary libraries
  #include <Wire.h>
  #include <Adafruit_MotorShield.h>
  #include <GPS.h> // Example library for GPS module
  #include <MPU6050.h> // Example library for IMU
  #include <OneWire.h> // Example library for ultrasonic sensor

  // Define constants
  #define ESC_FORWARD_PIN 4
  #define ESC_BACKWARD_PIN 5
  #define MOTOR_FORWARD_PIN 8
  #define MOTOR_BACKWARD_PIN 9
  #define GPS_TX_PIN 10
  #define GPS_RX_PIN 11
  #define MPU6050_SDA_PIN A0
  #define MPU6050_SCL_PIN A1

  Adafruit_MotorShield AFMS = Adafruit_MotorShield();
  Adafruit_DCMotor *motorLeft = AFMS.getMotor(1);
  Adafruit_DCMotor *motorRight = AFMS.getMotor(2);

  GPS gps(GPS_TX_PIN, GPS_RX_PIN); // Initialize GPS
  MPU6050 imu(MPU6050_SDA_PIN, MPU6050_SCL_PIN); // Initialize IMU

  void setup() {
    Serial.begin(9600);
    AFMS.begin(); // Start the motor shield
    motorLeft->setSpeed(255); // Full speed
    motorRight->setSpeed(255);

    // Initialize GPS
    gps.begin();

    // Initialize IMU
    imu.initialize();
  }

  void loop() {
    // Read GPS data
    if (gps.newNMEAreceived()) {
      gps.parse(gps.lastNMEA());

      // Example: Set the drone's position based on GPS coordinates
      float latitude = gps.latitude;
      float longitude = gps.longitude;

      // Example: Fly to a specific location using a pathfinding algorithm
      flyTo(latitude, longitude);
    }

    // Read IMU data for orientation and acceleration
    imu.readSensor();
    float pitch = imu.getRoll();
    float roll = imu.getYaw();

    // Example: Adjust motor speeds based on IMU readings
    adjustMotorSpeeds(pitch, roll);

    // Handle other sensor data (e.g., ultrasonic)
    // ...

    delay(10);
  }

  void flyTo(float latitude, float longitude) {
    // Implement a pathfinding algorithm to navigate to the specified location
    // This is a simplified example and would require more sophisticated logic
    // ...
  }

  void adjustMotorSpeeds(float pitch, float roll) {
    // Example: Use exponential decay modeling to control motor speeds based on IMU readings
    float speed = applyForge(currentSpeed, targetSpeed, k);
    motorLeft->setSpeed(speed);
    motorRight->setSpeed(speed);

    // Update the current speed for the next iteration
    currentSpeed = speed;
  }

  float applyForge(float current, float target, float k) {
    return target + (current - target) * exp(-k);
  }
  ```

  #### 4. Integrate the Code

  - **Upload the code** to your ESP32 using an Arduino IDE.
  - **Test the drone's flight behavior** by programming it to fly to predefined coordinates or navigate autonomously.

  ### Considerations:

  - **Safety**: Always ensure that the drone is tested and controlled within a safe environment.
  - **Battery Management**: Monitor battery levels and recharge the LiPo battery when necessary.
  - **Exponential Decay Modeling**: If needed, integrate Forge Theory to model exponential decay for more complex behaviors or control systems.
  - **Autonomous Navigation**: Implement a pathfinding algorithm (e.g., A* or Dijkstra's) to enable autonomous navigation.

  This guide provides a basic framework for building a drone flight controller using ESP32/Arduino. You can expand upon this by adding features like obstacle avoidance, object recognition, or more sophisticated AI-driven behaviors.

   * @brief How to Add a New Non-Blocking Animation
   *
   * This system uses a generic, non-blocking animation engine. To add a new
   * animation (e.g., for a "low battery" warning or "task complete" signal),
   * follow these steps:
   *
   * 1.  **Create a New Function:**
   *     Define a new function, like `void lowBatteryAnimation()`.
   *
   * 2.  **Define the Animation Sequence:**
   *     Inside your new function, create a `static const` array of `AnimationStep`
   *     structs. Each element in the array is one "frame" of your animation.
   *
   *     The `AnimationStep` struct has four fields:
   *     - `{ const LEDColor* ledColor, int soundFrequency, int soundDuration, int stepDuration }`
   *     - `ledColor`: Pointer to a color (e.g., `&LEDColors::RED`). Use `&LEDColors::OFF` to turn LEDs off.
   *     - `soundFrequency`: Tone frequency in Hz (e.g., `1500`). Use `0` for no sound.
   *     - `soundDuration`: How long the tone plays in milliseconds (e.g., `100`).
   *     - `stepDuration`: Total duration of this frame. The next frame starts after this time.
   *
   * 3.  **Call `playAnimation()`:**
   *     At the end of your function, call `playAnimation(yourStepsArray, numSteps)`,
   *     where `numSteps` is calculated with `sizeof(yourStepsArray) / sizeof(AnimationStep)`.
   *
   * 4.  **Trigger the Animation:**
   *     Call your new function (`lowBatteryAnimation()`) from anywhere in the code
   *     where the animation should start (e.g., from `power_manager.cpp` when the
   *     battery is low). The animation will run in the background without blocking.
   *
   * See `victoryAnimation()` or `startupAnimation()` for concrete examples.
