super bright LED Matrix für Robot Eyes

Post by stevemachine030 »

Hi,

for my project i need 2 super bright (outdoor) LED Matrix quadrad with side lenght of 80cm till 120 cm.

like in the skull project (http://learn.adafruit.com/animating-mul ... s/overview) i want to buid two synchornised LED Eyes for a robot. but it has to be bigger. I was thinking about 3x3 or 4x4 of the 1,2" LED matrices but one arduino can only run 4 (2x2) of them. (i think that it is so, but iam not sure

Iam very (very) new with arduino.
What product or products you can recommend?

We have these: http://www.adafruit.com/products/1487
They are even brighter, and RGB as well. You can control hundreds pixels with an Arduino UNO, and quite a few more with a Mega.

You need 3 bytes of SRAM for each pixel. Depending on the complexity of your code, you should be able to control 5-8 of these with an UNO. The Mega has 4-times the SRAM, so you could control quite a few more with that.
