During our early years, Betatronix primarily manufactured precision rotary potentiometers. It wasn't until Texas Instruments offered us the opportunity to work on the ...

Motorized linear potentiometers are a rare, exotic, and just plain neat input device most commonly found on gigantic audio mixing boards and other equipment that costs as much as a car.

Linear potentiometers produce a resistance output that varies according to the displacement or position of a slider or wiper. They are variable resistors with three leads. Two leads connect to the ...

A slider is just a potentiometer in a straight line, after all. These are wired up to an Arduino Nano, which sends the serial data to a Python script on the PC that changes the volume values ...
