/** light projector controller. How it'll work:
 * Potentiometer with a voltage dividor to send 0-5v into analog input.
 * Button [mode] to change modes.
 * Button [select] to select values within mode.
 * 
 * [modes] (press mode button to switch, select button to select children options to ajust with potentiometer):
 *  RGB shift
 *    rgb hue speed
 *
 *  Just white
 *
 *  Control RGBW
 *    R 
 *    G
 *    B
 *    W 
 *
 *  Chagne motor speed
 *    motor speed
 *
 *  OFF
