These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.

## Description

These are very thin variable potentiometers.

Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.

Unit comes with adhesive backing. The connector is 0.1" spaced and breadboard friendly. These potentiometers work great with a finger, or stylus.

We'd recommend using the [Arduino UNO R3](https://core-electronics.com.au/arduino-uno-r3.html) analog-to-digital converter to read the variable voltage of the softpot. Alternatively, any Arduino-compatible development board can be used.
