This linear slide potentiometer comes with an added kick – it’s not just a plain old slide pot! Underneath is mounted a slim geared DC motor that can gently move the wiper up and down, without human interaction. Often seen in very fancy A/V control panels, you could use these as linear feedback sensors for light robotics, or for interactive controls that can be controlled digitally as well as manually.
There’s also a ‘touch ‘pad that is electrically connected to the metallic slider, that you could connect to a capacitive touch sensor for detecting touch (this assumes that any slider knob you add on is metallic or conductive)
So, say if you want to move the slider to the middle, your code will have to read the potentiometer analog voltage while slowly powering the motor one way or the other until the analog reading reaches the desired spot, then ‘release’ the motor!
Comes as one motorized slide pot – H-Bridge controller is not included; any Arduino-like microcontroller will do the job nicely.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
