We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan.

It’s a simple enough set-up in which a voltage controlled current source feeds the pot while an Arduino with a motor controller turns it through a stepper motor, and takes a voltage reading from ...

So he grabbed an Arduino, potentiometers and a button and hacked together what a joke-yoke. The genius part of this hack is the way [Christopher] used his desk drawer for pitch control.
