Author: Alejandro Palacios (pamanes@gmail.com)
Creation Date: Jan. 10, 2015
Purpose:
This is a clock program that pushes the time
to Shift Registers in order to light up Nixie Tubes.
H H : M M : S S (Nixies)
| | | | | | (Rusian Driver has 10 output pins, each lighting up a number)
D D D D D D (Russian Driver K155NA1)
\/ \/ \/ (4 pins to each Russian Driver)
SF3 SF2 SF1 (each shift register has 8 output pins - 74HC595)
There are three Shift Registers, each controls two nixie tubes
