DESCRIPTION
Make a scrolling sign, or a small video display with this 8x8 gridded yellow-green LED matrix.
Only 1.2" on a side, it is quite visible but not so large it wont plug into a breadboard! There are
16 pins on the side, 8 on each, with 0.1" spacing so you can easily plug it into a breadboard with
one row on each side for wiring it up.
Since the display is in a grid, you'll need to 1:8 multiplex control it. We suggest either using a
74HC595 and TPIC6B595 (using the 74HC' to control the 8 anodes at once and then using the
TPIC' to drive one cathode at a time) or just using a single MAX7219 which will do the
multiplexing work for you.
The Arduino playground has a nice set of tutorials introducing the MAX7219 and 8x8 LED
matrices
