/***************************************
This shows the use of the Snooze USB

Serial in sleeping appilcations.

// Always use SnoozeUSBSerial with T4.0.

// "println", "prinf", etc and also handles the effects of using -
// the Arduino Serial monitor and sleeping. Use it when you -
// want to print to serial monitor for sleeping applications.
