Sure! I can help you with the Arduino code for an autonomous "follow me" cooler. Below is a simplified version of the code that integrates the components you mentioned (Arduino Uno, HC-05 Bluetooth module, PAM-7Q GPS, HMC5883L compass, and L298N motor driver). This code assumes you have basic working knowledge of Arduino and its libraries.
Required Libraries
Make sure to install the following libraries:
  • SoftwareSerial for Bluetooth communication
  • TinyGPS++ for GPS
  • Wire for I2C communication with the compass
  • HMC5883L (Adafruit's library for the compass).
Connections
  • HC-05: Connect TXD to Arduino D10, RXD to Arduino D11
  • GPS (PAM-7Q): Connect TXD to Arduino D8, RXD to Arduino D7
  • Compass: Connect SDA to Arduino A4, SCL to Arduino A5
  • Motor driver: Connect ENA, IN1, IN2, IN3, IN4, and ENB to the appropriate Arduino digital pins.

  }

  if (gps.location.isUpdated()) {
    double latitude = gps.location.lat();
    double longitude = gps.location.lng();
    Serial.print(F("Latitude= "));
    Serial.print(latitude, 6);
    Serial.print(F(" Longitude= "));
    Serial.println(longitude, 6);
  }

  // Get compass readings
  Vector norm = compass.readNormalize();
  double heading = atan2(norm.YAxis, norm.XAxis);
  if (heading  2 * PI) {
    heading -= 2 * PI;
  }
  
  heading = heading * 180 / PI; // Convert to degrees
  Serial.print(F("Heading: "));
  Serial.println(heading);

  // Example motor control based on heading (simple case, needs expansion based on your logic)
  if (heading > 0 && heading  0) {
    char command = (char)bluetooth.read();
    if (command == 'f') {
      moveForward();
    } else if (command == 'b') {
      moveBackward();
    } else if (command == 'l') {
      turnLeft();
    } else if (command == 'r') {
      turnRight();
    } else if (command == 's') {
      stopMoving();
    }
  }
}

void moveForward() {
  digitalWrite(motorPin1, HIGH);
  digitalWrite(motorPin2, LOW);
  digitalWrite(motorPin3, HIGH);
  digitalWrite(motorPin4, LOW);
}

void moveBackward() {
  digitalWrite(motorPin1, LOW);
  digitalWrite(motorPin2, HIGH);
  digitalWrite(motorPin3, LOW);
  digitalWrite(motorPin4, HIGH);
}

void turnLeft() {
  digitalWrite(motorPin1, LOW);
  digitalWrite(motorPin2, HIGH);
  digitalWrite(motorPin3, HIGH);
  digitalWrite(motorPin4, LOW);
}

void turnRight() {
  digitalWrite(motorPin1, HIGH);
  digitalWrite(motorPin2, LOW);
  digitalWrite(motorPin3, LOW);
  digitalWrite(motorPin4, HIGH);
}

void stopMoving() {
  digitalWrite(motorPin1, LOW);
  digitalWrite(motorPin2, LOW);
  digitalWrite(motorPin3, LOW);
  digitalWrite(motorPin4, LOW);
}
This code acts as a starting point for your project. It initializes communication with the GPS, compass, and Bluetooth module. It grabs the GPS coordinates and compass heading, which can be used to control the navigation of the cooler. The Bluetooth module provides a simple interface for manual control.
Make sure to adjust the logic for following the phone's coordinates and implementing more sophisticated navigation behaviors. Feel free to ask if you need any specific part of the code expanded or explained further!

Autonomous "Follow Me" Cooler

An Arduino Uno powers this autonomous “follow me” cooler that connects to a smartphone via Bluetooth and uses GPS to navigate. The robot cooler connects to a smartphone via Bluetooth and uses GPS to navigate. All the electronics will be contained in the base so that other objects can be carried as well. The electronics were installed in the box cutout under the platform. An Arduino Uno and a 5v battery to power the sensors, Bluetooth, and control logic. A 3s LiPo battery was used to power the motors. A HC-05 Bluetooth module was mounted at the front of the platform for better range. The rest of the components including a L298N motor driver, PAM-7Q GPS, and HMC6883L compass were mounted inside and connected to the Arduino through the breadboard. The compass works with I2C, so we connected the SLC and SDA pins to A5 and A4 respectively. The rest of the pins were connected through digital I/O.
