Dual 8x8 LED Matrix

8x16 LED Matrix Display.
Components:
Arduino Mini Pro (and Arduino could be used) x 1
74LS595 Shift Registers x2
8x8 LED Matirx Displays (Common Anode Row) x 2 (I've used bi-colour displays but only connect the green LEDs).
270 Ohm 1/4 W Resistors (Current limiters for LEDs, 1 per column) x 16 - The spec for the LEDs would allow ~150 Ohm resistors to be used but I did not have enough to hand).
Breadboard + jumper wire.

Software:
I wrote a simple program to display the ASCII characters between code 32 and 127, plus some custom test characters. Essentially it scrolls the contents of the character bitmap array. The garbage at the end is a result of a coding against a buffer overrun.
