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:

}

This code is a basic template for the Arduino UNO. The setup function is used to initialize any settings, and the loop function runs continuously, allowing for real-time control and monitoring of the connected components.
