Countdown

.. tags:: tiny, artistic



This program displays a digital timer that counts down to zero. Rather
than render numeric characters directly, the sevseg.py module from Project
64, “Seven-Segment Display Module,” generates the drawings for each digit.
You must create this file before the Countdown program can work. Then, set
the countdown timer to any number of seconds, minutes, and hours you like.
This program is similar to Project 19, “Digital Clock.
