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 sensors and other components, and the loop() function is where you place the main logic that runs repeatedly.
