Documented Code

Arduino Mega 2560 Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a template and does not contain any specific logic for controlling the circuit. The setup() function is intended for initialization code that runs once, while the loop() function contains code that runs repeatedly, forming the main part of the program. To control the motors and communicate with the Bluetooth module, the code needs to be developed further with appropriate function calls and logic.
