Code Documentation

Arduino Leonardo (Rev3b) 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 Leonardo. The setup() function is where you initialize your components, and the loop() function is where you place the main logic that runs repeatedly.
