Hey I just got a Duemilanove kit, and I want to use it to power a lot of LED's. I have about 100 common cathode RGB LEDs that I never used on my last project and I want to make a giant strip out of them for my ceiling.
So I guess my question is, how many RGB LED's can I power, using only the Duemilanove? If it is substantially less than 100, what do I need in order to be able to power all of them.
Please note that I want it so that all LEDs are the same color at the same time, so there is no need to worry about a second channel or something.
Sorry if this is in the wrong section also! im a newb
