I am making an attempt to produce a LED color controller that will produce 256 colors using potentiometers.
BUT I can't get the pots to resist the voltage down low enough that the LED's individual colors do not glow at all.
According to my math a 10k pot should resist the voltage far below the operating voltage but alas it still glows.
I KNOW THIS CAN BE DONE EASIER WITH A MICRO CONTROLLER.
I WANT TO MAKE THIS ON THE CHEAP SO NO MC's
Thank you so much in advance.
I am a DC circuits noob so please explain well, and I am not shy of reading large hidden forum pieces on this subject.
