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, and the loop function contains the main code that runs repeatedly. In this circuit, you would typically add code to control the relay based on your specific requirements.
