Just a quick heads up, i'm pretty much a novice when it comes to this sort of thing. Have just got hold of a few bits I think I shall need for my project.
Basically I have a small 20cm strip of RGB LED's.
I need to control this with a potentiometer.
Basically I want it to be a 180 degress turn. fading from Red to off to blue. (Off being at 90degrees)
I have an Arduino UNO experimentation kit, 10k ohm linear pot, 3 x TIP121 TRANSISTORS, RGB LED STRIP and a bunch of resistors.
Does any of this sound particulay difficult? Can anyone spot any problems I might have?
Do I need 12V? or can I use a 9V battery?
Sorry if these are silly questions!
