The potentiometer has three pins, pin 1 is not connected, pin 2 is connected to the output end, and pin 3 is connected to the input end. A potentiometer is a resistive element with three leading ends and the resistance value can be adjusted according to a certain changing law. A potentiometer usually consists of a resistive body and a movable brush. When the brush moves along the resistor body, the resistance value or voltage that has a certain relationship with the displacement is obtained at the output end. Potentiometer function: 1. Used as a voltage divider Potentiometer is a continuously adjustable resistor. When adjusting the handle or sliding handle of the potentiometer, the moving contact slides on the resistor body. At this time, the output voltage of the potentiometer can be obtained in a certain relationship with the applied voltage of the potentiometer and the rotation angle or stroke of the movable arm. 2. When the potentiometer is used as a varistor, it should be connected as a device at both ends, so that a smooth and continuously changing resistance value can be obtained within the stroke range of the potentiometer. 3. Used as a current controller When the potentiometer is used as a current controller, one of the selected current output terminals must be the sliding contact terminal.
