Looking at using a ucontroller to control LED's for dimming / mood lighting. The idea would be that on the main unit, there would be a small LCD display that with a number of buttons, one could change between each of 4 colours to control, and then use a couple more buttons to adjust the brightness levels up and down. That part is easy enough to get working with the ucontroller. However, the idea is that these LED's are in clusters (50 clusters of 4 LEDs, one of each colour), that are all chained together. Each colour would be operated as a single channel.
My question is this. Instead of having to run wires for each colour out to all the clusters (GND, RED, BLUE, GREEN, WHITE), is there a single chip that can decode a single wire signal and change brightness levels on 4 channels (+5V, SIGNAL, GND)? I'm not even sure of what I should be searching for to find hints on what I want.
Sorry if I confused anyone.
