void loop() {
  // put your main code here, to run repeatedly:

}

The provided code is a template with empty setup() and loop() functions, which are the standard structure for Arduino sketches. The setup() function is intended to contain initialization code that runs once when the microcontroller is powered on or reset. The loop() function is for code that runs continuously as long as the microcontroller is powered.

Further implementation details would be required to provide a functional sketch that interacts with the connected components.
