Linear SoftPot (Ribbon Sensor) (100mm)

The Spectra Symbol SoftPot ribbon controller is a thin, adhesive-backed linear potentiometer that outputs a variable analogue voltage based on touch position, ideal for compact and responsive user input.

---

Manufactured by Spectra Symbol, these are nice little ribbon controllers (also known as 'soft potentiometers') with an adhesive backing.

There is a nominal 10K resistance across the two outer leads. The middle pin resistance with respect to either of the outer pins changes depending on where on the strip one presses. When no pressure is applied, the middle pin floats, so be sure to use some sort of weak pullup, such as 100K ohm.

To use Connect one side pin to ground via a 10K resistor in series. Connect the other side pin to your Vcc power line (3V, 5V etc) via a different 10K resistor in series. Then read the analogue voltage on the centre pin. It will range from 1/3 Vcc to 2/3 Vcc .

Please note: Do not connect to Ground and Power directly! Breadboard not included.
