Motorized slide potentiometers, or "flying faders", are incredibly cool. They are most commonly found on large mixing boards at high end recording studios, used to allow fine control of audio levels while permitting pre-set positions to be recalled in real-time.

They consist of a slide potentiometer, and a motor that can convert rotational motion to linear motion, and either a capacitive touch sensor or current sensor to allow interaction with the fader while it is moving (the sensing prevents motor stalling or stripping of gears).

This guide will show you how to use the motorized slide pot with touch sensor in your projects -- this can be anything from lighting control, to MIDI synths, to animatronics, or home automation!
