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 initializes the Arduino UNO and contains empty setup and loop functions. The setup function runs once when the Arduino is powered on or reset, and the loop function runs continuously. You can add your specific code to these functions to control the components connected to the Arduino.
