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 where you initialize your settings, and the loop() function is where the main code runs repeatedly. You can add motor control logic in these functions to control the DC motors via the L298N motor driver.
