Has anyone used a Pololu Force-Sensing Linear Potentiometer: 4.0″×0.4″ Strip. If you apply a force to the strip it should give you a pressure reading and a position along the strip.
I have both the pressure and position along the strip working but the values only make any sense for the first inch. The remaining 3 inches of the strip are maxed out at a reading of 4096. I have tried different resistors but without success. Does anyone have any suggestions?
An example program is at https://github.com/pololu/fslp-led-strip-arduino-demo/blob/master/FslpLedStripDemo/FslpLedStripDemo.ino .
The example uses an LED strip but that can be ignored reasonably easily.
