Make a scrolling sign, or a small video display with this 8×8 gridded cool white LED matrix. Only 1.2″ on a side, it is quite visible but not so large it won’t plug into a breadboard! 64 white 250mcd LEDs are contained inside the plastic body, in an 8×8 matrix. 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 singleMAX7219 which will do the multiplexing work for you.

The Arduino playground has a nice set of tutorials introducing the MAX7219 and 8×8 LED matrices.
