Colorful thing to display stuff on.. (or Arduino + LED Matrix)
Loading...
Uploaded by nappii on Jul 31, 2009
Arduino Duemilanove and Sparkfun RGB LED matrix with backpack. Work in progress, very much so.
Arduino deals with all the calculations and serial is only used for transmitting email and feed counts. Python handles the data parsing and serial communication.
It actually looks less awful in reality. The colors rotate (with different hue limits) on the other 'views' as well, but you can barely see it on this video. My camera might not be best suited for the task.

Wow

wow excellent great patterns.
-
cool stuff! makes my 5x5 single color arduino driven matrix look pretty simple ^^
-
hey! could i please grap the code for that display??
-
can u post the code?
-
Neat! And you used python pc-side: even better! :)

Very Nice..
Is it possible to share the code for educational reasons :) ?

Thank you!
Not at the moment, I'm afraid. Current code still needs some work and I'm hoping to add more functionality as well. Too bad I don't have much spare time at the moment for educational reasons. So, I can't promise you anything.

nice, im going to start working with arduino i think, it seems like a really nice platform, i was thinking about ultimately making a custom midi controller or something similar. have your found any limitations on the board?

Thanks.
Not really, no. I guess it could be a bit slow and have too little memory for some purposes but that hasn't been a problem for me so far. In any case, it's a great board/platform to get started with.

hey nice job first off! but how did you write the code and what did you use other than the arduino

Thanks! The backpack that came with the matrix has ATMEGA168 and 3x74HC595D. You only have to send the color of each LED as a char of format RRRGGGBB.
I sketched the part that determines the colors in Processing (I didn't even have the parts yet) and then rewrote it in C. The colors of the LEDs are simply proportional to the distance of an abstract ball that bounces off the walls and has a rotating hue.
Didn't use any additional components other than Arduino and the LED matrix with backpack.
