Could someone explain how a 6 wire servo works? I found one when I
opened up an RC toy car from Radioshack.
It has 2 wires that go to the motor and 4 wires that go to some kind of
pot I think: on a small board are 2 etched concentric circles which are
in contact with a 4-pronged device mated to the spinning gear. Two of
the 4 prongs touch the outer circle, the other two the inner circle.
I know how to program 3 wire servos but don't understand the purpose of
the extra "pot" of the 6 wire servo.
