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 settings, and the loop function is where the main code runs repeatedly.
