Idea for new product.

Well I think a board that could control hundreds of leds would be great ,even if rainbowduino exists

for this kind of projects the outputs are not enough .

It could be a shield for arduino or a dev board (I prefer the shield solution) with as many as multiplexers arduino can handle and fit in a shield and pins for the outputs .

Such product would be great since the numbers of pins issue has been wandering in many people’s minds.

Hey you checked out the MondoMatrix LEDMatrix?

Yes I have checked this out ,but it cannot be controlled with arduino and I dont have money to buy and the dev board

for this one since its above my budget .

MondoMatrix products are modular. Multiple LEDMatrix modules can be connected together to “control hundreds of leds” (actually, it’s thousands).

Their Displayduino, which acts as the controller, is such a neat product in that it has screw terminals and has an for RS485 communication to the modules.

It would be really nice if Sparkfun stocked the patch shield for Arduino. It seems to be a great shield, and potentially very useful, although not many people stock it. You could, I guess create something very similar that was Sparkfun branded. Thanks. “http://info.yawp.com/kits/patch-shield-v05/
