Documented Code

Arduino Nano 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 Nano. The setup function is used to initialize any settings or configurations, and the loop function contains the main code that runs repeatedly.
