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 components and settings, and the loop() function is where the main code runs repeatedly.

This concludes the documentation for the circuit.
