8 x 8 LED Matrix by oomlout

Description

In honour of Thingiverse Thursday here's a design that has been sitting on our hard drive for a little while.

Its a simple little box that makes wiring up an 8 x 8 LED Matrix easy. It uses the MAX7219 (or 7221) LED driver chip from Maxim and uses the Matrix library in the Arduino library.

For Details on how to wire up and program try:

Instructions

Cutting
Cut from any 3mm stock. (Cut-Black, Engrave-Blue, Ignore-others)

Assembly
A few 3mm x 10mm screws, and some soldering.

Wiring
Download the breadboard layout sheet pdf. Print it (important do not scale). Follow the guidelines and connect it to an Arduino.

Programming
Try out the demo programs in the Arduino IDE. Or for scrolling messages you can use the program we wrote (it is quite clunky and may need a little tweaking) (downloadable below).

We hope you enjoy and if you have any questions or need any help we'll try our best on help@oomlout.com )
