Code Documentation

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 where you initialize your variables, pin modes, start using libraries, etc. The loop() function is where you write the main code that you want to run repeatedly.
