+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.
