Documented Code

Arduino Nano 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 template provides the basic structure for an Arduino sketch, with setup() and loop() functions defined. The setup() function is intended for initialization code that runs once when the microcontroller is powered on or reset. The loop() function contains the main logic of the program, which runs repeatedly as long as the microcontroller is powered.
