Code Documentation

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 where you initialize your components and settings, and the loop() function is where the main logic of your program runs repeatedly.

This document provides a comprehensive overview of the circuit, including the components used, their wiring, and the embedded code. This should serve as a useful reference for understanding and replicating the circuit.
