Enigma Code. This Arduino Mega custom shield is programmed to replicate
exactly the behavior of a true German M4 Enigma machine.
It uses 4 16-Segment units, 5 LEDs, 26 Lamps setup as keyboard, 26 keyboard buttons
& 10 Function keys. The 115 light emitting diodes are multi-plexed to minimize the
amount of pins needed down to 38 and all 36 pushbuttons keys are sharing a total of 4 pins.
Designed, assembled & programmed by Marc Tessier & James Sanderson 9/20/13
Modified for our Prototype PCB pair on 12/4/13.
Modified to obey doublesteping and have M3 function 22 MAR 14
