I'm using a motorized fader that has a "touch sense" pin (see this data sheet), which should be able to detect when someone touches the fader. I want to use it to stop the motor and switch from setting to reading mode. I'm using a Netduino Plus 2 to read the value of the potentiometer and a motor-shield to control the motor (that part is working perfectly).
I have been told that the touch sense pin is to be used to measure capacity in order to detect touching. I was hoping to just connect it to a analog input but was warned that it could potentially damage the Netduino.
How would a typical "touch sense" circuit look like when connecting to a analog or digital input? (The Netduino Plus 2 measures voltages between 0 to 3.3V).
