Hey all,

Really new to this, whats the easiest way to control multiple RGB LED's separately? I can code up one RGB, but a bit unsure of the best way to code up and power  5 or 6 at once.  I have a uno board and need to control about 6 rgb LEDS.

Cheerio,
Rup

What do you mean by 'control'? Do you want color fading? How accurate? Do they all have to be independent or do they all show the same color?

A TLC5940 chip is commonly used but you can only do 5 RGB LEDs per chip. You'd need two of them for six LEDs.

I would definitely use the TLC5940.  I'm currently using 8 of them to control 42 RGB LEDs in a project I'm working on.

WS2803 has 18 ports so ideal for controlling 6x RGB LED's

Cool. I didn't know about that one...

It looks easier to control than the TLC5940 as well. You only need two wires and no messing about with timers to drive the PWM clock.
