Me Slide Potentiometer is one type of potentiometer that can be used to control volume, light intensity, motor speed, movement control, etc. in interactive projects.
This Me Slide Potentiometer can be combined with Me Orion (or other Arduino IO/sensor expansion board) in interactive projects. Move the lever from one side to the other, its output voltage will range between 0 V to the VCC you apply. The VCC Me Slide Potentiometer supports vary from 3.3V to 5V.
