Documented Code

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

}

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

}

The provided code is a template for the Arduino UNO microcontroller. The setup() function is intended for initialization code that runs once at the start, while the loop() function contains code that runs continuously. Specific functionality must be added to these functions to control the connected components as per the requirements of the circuit's application.
