I bought the RGB matrix and the matrix backpack controller from SparkFun Electronics.

The RGB matrix is just a simple grid of RGB leds but if you attach the backpack controller to it you can control it easily using an Arduino or AVR or any other microcontroller that can speak SPI (a serial protocol).

In the video above I had it set up so it simply calculated some colour values and then sent them to the RGB matrix (via the backpack controller). The values I calculated resulted in the coloured lines seen in the vid. It’s all pretty straightforward

I started writing a C# program that allowed me to draw animated graphics and then send it to the RGB matrix but it isn’t finished 100% yet. Let me know if you want the source or anything.

Here are some links that might help you get started:

* Code to control the RGB matrix serially – http://www.arduino.cc/playground/Code/RGBBackpack

Let me know if you have any problems and I’ll try to help you out!

I think its excellent explanation but I would ask if you design this matrix

you do not help me, as I design a matrix rgb, or elements that I have to develop the control circuit for a matrix of 8×8, thanks
