Do you know anything about motorized pots and the BS2?
Are these pots essentially DC motors and controlled as such?

Thanks,
Jordan

    Yes.

    Usually. A good example of a "motorized pot" is your typical hobby servo; a
    DC motor turns the axle which is connected to a pot which provides a
    feedback voltage to the motor controller which compares the pot's voltage to
    a voltage from an input PWM and turns the motor until the two voltages
    match.

    I've used the servo electronics to drive motorized pots. This is much
    simpler since I can then control everything from a single PWM signal.
