Sliding Adjustable Potentiometer
The Slide Potentiometer module with PH-2.0-4P interface incorporates a linear variable resistor with a maximum resistance of 10K; Can be used to adjust the speed, brightness. When you move the slider from one side to the other, its output voltage will range from 0 V to the VCC you apply. It connects to the other Grove modules through a standard 4-Pin Grove Cable. The LED pin is connected to a on-board red indicator LED which is used to visually represent the resistance change on the potentiometer.
