Linker Slide Potentiometer Module for Arduino

The slide potentiometer is a linear variable resistor with a total resistance of 10k. When you move the lever from one side to the other, its output voltage will range from 0 V to the VCC you apply. It has four pins, 3 of which are connected to VCC, GND and the ADC IN on the slide, while the remaining pin is connected to a red indicator LED. You can use the indicator LED to visually display the change on the potentiometer.Dimensions: 60.0(L) × 24.0(W) × 20.0(D)mmLinksprite Page  For More info on Arduino.
