Audioguru, Thanks for your reply. My initial idea was to use a unique PWM for each channel. This should work but to get white each channel will require a different duty cycle. I looked in to driver chips but haven’t found something simple enough yet. The problem is that I only have so many pins that I can use! So, are you aware of any pitfalls with RGB LEDs or should I just get one and start experimenting? Thanks, MadThug (Should change to Mad Geek) :-X

Greetings, I am searching for methods of driving RGB LEDs with a microcontroller such as a basic stamp. I’d like to fashion the LEDs in an array capable of displaying a range of colors. Do any of you have experience with these things? Can RGB LEDs be controlled using PWM for each channel? Do they require unique circuitry? Thanks, MadThug ???

I just wanted to thank GreekPIC and MP for supporting this project for free. I'm excited to get started on my own gantry mill. -MadThug ;D

Uhh... at the risk of sounding stupid, what program can be used to open the "___.ps" file exention? Thanks, MadThug ???
