The slide contains two separate 10k audio taper potentiometers so that you can use one as servo-feedback in order to read the position of the slider and use the other to control whatever your target is. There is also a touch sense line which is electrically connected directly to the metal slider tab so that you can interface the slider with capacitive touch circuitry.
You can use this modul as pulsing the motor to provide haptic feedback in your small-scale projects.
