Code Documentation

Arduino Micro (Rev3) 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 Micro (Rev3). The setup() function is used to initialize any settings or configurations, and the loop() function contains the main logic that runs repeatedly.
