How does the Potentiometer work?

A potentiometer works by having a metal wiper move along a track between a wiper terminal and a output terminal. Increasing and decreasing resistance as it moves.

Circuit 3: RGB LED

showSpecturm() only.

Everything under this code must be blocked off (not working anymore) to show only showSpectrum(). Other the things that deal with showSpecturm()

For example the showSpectrum() code in fine but the rest is blocked off
