Unusual clock with AT89C2051
Posted by admin on November 10th, 2007
Strangeness of this clock is in its expression of numbers, which is realized using seven Leds. Leds are located inside a pipe, one above another and if we move Leds enough fast left or right, we have a space where we can write numbers, characters or anything else. All these are possible only if we turn on specific Leds at precision timing. Moving LEDs left or right is achieved using a steel plate, so we have to tense the pipe in one direction (left or right) and let pipe to vibrate by itself.
