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 used to initialize any settings, and the loop function contains the main code that runs repeatedly. You can add your specific logic for interfacing with the sensors and actuators in these functions.
