RGB ledstrip
The urge to build something was there again, so i ordered this LED-strip from dealextreme.com
Waiting for the LED-strip to arrive I already wrote the software part, it looks like this:
When I click or drag anywhere in the spectrum it sends the RGB values to the arduino.
When the LED-strip arrived I bought some transistors (BUZ11′s, extreme overkill, but hey.. ) and hooked everything up.
End result:

What did you use to power the rgb strip? I assume not the 5v from the arduino..

12V DC, thats what the transistors are for, to switch the 12V source with the 5v arduino signal.
