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, with 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 setup() has completed. You can add your specific initialization and main code logic within these functions.
