the speed of a DC motor in both the forward and reverse direction, from
fully OFF to fully ON in either direction, using the single potentiometer.
Uses pulse width modulation for maximum motor torque.
This system eliminates the danger of damage to both the control board
and motor that is associated with sudden voltage reversals possible
in boards that have just a simple DPDT polarity switch. With our controller,
turning the pot in one direction causes the motor to start spinning.
Turning the pot in the other direction causes the motor to spin in the
