In this video I am testing a capacitive proximity sensor. I show you how to wire it up with a microcontroller and how to control a stepper motor with it. At the end of the day, it is just a switch, so the coding part does not differ in this sense (you have to poll the pin or use interrupts). Only the wiring needs a bit attention due to the higher voltages.
