Potentiometer test

The potentiometers work with the RGB led. It should be fine with a 9v battery, but I'll test it just in case anyway.

Below are pictures of the circuit and a drawn diagram of it.

Basically the turning gear is attached to the "poll" of the potentiometer.

You can get a full range of colours just like when the colour cycle was controlled by the Arduino. True, controlling the colours with Arduino is more sophisticated while the potentiometer is more basic and crude. But that's the point of it. Reducing the interaction into something that is dominantly physical and less controlled through digital means.
