This is a BIG clock, a sub-project derived from the original small
"digital clock date thermometer for PIC16F84/PIC16F628/PIC16F690".
The code is exactly the same, but the hardware part is changed.
In the original clock, 4x7 segment display is used. Those digits
could be turned on easily using some common small power transistors (200mA).
This particular project uses either 14 legs/segment or 6 leds/segment which
requires bigger source power.
