RGB LED Tutorial (using an Arduino) (RGBL)

Step 6 Finished

By this point you've mastered controlling an RGB LED all that's left is coming up with great ideas on how to use it.

We have loads of plans for them around oomlout HQ and we'd love too hear about what you get up to. Please leave a coment below or send us an e-mail to [e-mail] with any details.

Where did you get that glowing USB cord or did u make it ?

 Thank you for posting this info and the sample code! It's a big help.

I'm using some 4 pin Common Anode RGB LEDs w/ 220ohm resistors to good effect. My LED pins are the straight kind, different from your example but same enough. With the long pin Pin2 (second in from the left) they are Pin1.Green; Pin2.Power(+5v); Pin3.Blue; Pin4.Red. I'd been having trouble because I'd connected Pin2 to Ground, which might be true for Common Cathode? Anyway, your example gave me some concepts to play with and I got it working. Thanks!!!

I've integrated my PWM RGB LED with some random value generating code to produce an Arduino mood light that changes into a notification light when signaled from "Processing" over the Serial Connection.

Maybe I'll turn it into my first instructable. :)
Cheers!
