Clock

This project is based off of a schematic I stumbled
across on the internet.  I do not know who created it
because I have since lost the original schematic.
However, if you happen to be that person, please let
me know.  It works by using 12 LEDs connected to
a PIC16F84 microprocessor and uses PWM to
make one LED brighter than the others to signify the
hour and minute and then successively turns off other
LEDs to show the passing of minutes between
multiples of five.  That description may not have made
any sense, but that isn't really important.  The hardware
of the device is fairly simple: 12 LEDs, 1 PIC16F84,
timing resonator, a momentary switch and a few
resistors.
