Documented Code

Arduino Mega 2560 Code

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

}

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

}

This code is a basic template for the Arduino Mega 2560. The setup() function is used to initialize any settings or configurations, and the loop() function contains the main code that runs repeatedly.

This concludes the documentation for the circuit. Each component and its connections have been detailed, and the code for the Arduino Mega 2560 has been provided.
