Product Description

Replacement: None. There is no direct replacement for this item. This page is for reference only.

Description: An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user!

This is a center-tap taper type potentiometer. The outer two pins will always show 500K resistance, the center pin resistance to one of the outer pins will vary from 500K Ohm to about 50 Ohm. This is a taper-type pot meaning the resistance will vary non-linearly with its position. This is commonly used for audio and volume control applications.
