Documented Code

Arduino UNO 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 UNO. The setup function is where you initialize your settings, and the loop function is where the main code runs repeatedly. You can add your motor control and sensor reading logic in these functions.
