Before I get into my little problem, let me start by saying I've only had my Arduino for a week and I absolutely love it... I'm a total n00b when it comes to electronics so if you guys could help me out, I'd really appreciate it.
I picked up a few of these RGB LEDs: http://maplin.co.uk/Module.aspx?ModuleNo=35893
The datasheet is here: http://www.maplin.co.uk/Media/PDFs/N63AX.pdf
I've managed to get two of them working, but I've now used up all the PWM pins on my Arduino. :( I want to hook up another two and have each be able to be any colour.
I was wondering how I would go about this? Do I need to use a shift register? From what I've read that won't work with PWM. I'm really quite confused at the moment, so any help would be greatly appreciated!
