Hello

I want to integrate the Spectra Symbol Softspot sensor into my model and use it as a kind of buton sellector whereby different things are triggered depending on where the sensor is touched. I have been looking for a tutorial for this as I am not sure whether I treat it like a standard three pin potentiometer. Could anybody help on this please.

here is the product: Softpot Rotary Potentiometer - SEN-08678 - SparkFun Electronics

Many thanks

Yes just treat it like a standard Pot.

Except I think you need a pull-up resistor to get a known value when nothing is being pressed.

Good point, forgot about that one, a high value pull down to ground on the wiper. Or a high value voltage divider with equal resistors. It depends on what you want it to read when it is not pressed.
