"""
Demo of a simple combination of parts from Electric Dollar Store:
* POT - potentiometer
* DIG2 - 2-digit display
* BEEP - piezo beeper
This demo simulates a kitchen egg-timer.
Twisting the POT sets a countdown time in seconds,
and after it's released the ticker starts counting.
When it reaches "00" it flashes and beeps.
