These motorized sliders are very cool. Each is essentially a standard slide pot which is belt-driven by a small motor. The slide contains two separate 10k linear 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.
Motorized potentiometers are useful when you need the ability to jump to preset positions or when you want physical feedback from virtual controllers. There are also a variety of unconventional uses for these potentiometers such as pulsing the motor to provide haptic feedback or just using it as a linear actuator for super light-duty robotics.
The two mounting holes that are bent to accept screws from the side look like it needs M3 screws => “2- M3x0.5” [ http://cdn.sparkfun.com/datasheets/Components/General/MD100AM2BF-D_L_MD100AM2B-D.jpg ].
In the demo video [ https://www.youtube.com/watch?v=E2Stni6W7Vc ] used a motor driver [ like the recommended motor driver TB6612FNG – https://www.sparkfun.com/products/9457 ] and Arduino microcontroller to move the motorized slide potentiometer. Unfortunately, they did not provide the demo code from the video. There should at least be an example code on using a motor driver with the TB6612FNG’s product page.
Try looking at this comment though => https://www.sparkfun.com/products/10976#comment-53d36766ce395ff8478b4568 . A customer was able to get it working similar to the demo. The code does not seem to be exactly like the demo code but it is a start.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

You would think they would stock the slider knobs for these things. I had to print my own on a 3D printer.
Hi, You make a good point. I have passed your suggestion along to our parts hunting team for consideration. Thank you
The rubber band was too loose and not reliable
