Abstract
A position indicating circuit includes: first and second input terminals for respectively receiving first and second voltages; an output terminal; a first resistor; and a second resistor having a first terminal coupled to the first input terminal through the first resistor, a second terminal coupled to the second input terminal, and a third terminal coupled to the output terminal. The second resistor is used to be actuated by a pedal of a foot controller of a sewing machine such that a voltage at the output terminal has a magnitude related to a position of the pedal. A detecting system that uses the position indicating circuit and that can determine whether the foot controller is coupled to a main body of the sewing machine is also provided.
