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, containing empty setup and loop functions. The setup function runs once when the microcontroller is powered on or reset, and the loop function runs continuously after the setup function has completed.
