Having just started experimenting with an Arduino I figured I would build one as my second Arduino project with a 4 in 1 8x8 LED matrix I bought a while ago and to add some additional features. 50/month or $69/year. This is a very easy project for starters like me, the idea of it is to show you how to send bytes to an 8x8 LED matrix. Our LED display systems are seamless, providing clear and detailed imaging. This version of the LED backpack is designed for these very cute miniature 8x8 matrices. Uploaded 19/08/2011. Though out playing with this I've learnt about shift registers and how we can use them along with a transistor array chip. not use up the Digital pins on a micro-controller) shift registers are used. I will be building my own LED matrix for this project using 5mm leds and a prototyping board from Radio Shack.
