Code Documentation

Arduino UNO Code

#include <L298N_MotorDriver.h>

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code includes the L298N motor driver library and sets up the Arduino environment. The setup function is where initialization code would go, and the loop function is where the main code would run repeatedly. Currently, both functions are empty and need to be filled with the appropriate logic to control the motor and LED.
