Documented Code

Arduino UNO Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

The provided code for the Arduino UNO is a template with empty setup() and loop() functions. The setup() function is intended for initialization code that runs once, while the loop() function contains code that runs repeatedly. Specific functionality needs to be implemented within these functions to control the circuit's components.
