contains the servo’s control circuits, a DC motor, and gears. These parts work together to
take high/low signals from the BASIC Stamp and convert them into positions held by the
servo horn.

servo. Keep in mind that the LED circuit is not required to help the servo operate. It is
just there to help see what’s going on with the control signals.
