hello! it did try the controller with a little Potentiometer and it worked good.
now i will try to use it with a hall sensor like [https://www.conrad.at/de/hallsensor-ab-elektronik-9168000010-5-vdc-messbereich-45-45-stecker-amp-182865.html](http://conrad sensor)
and i was not able to get readings that are changing
i did test both sensors with my arduino and they worked very well…
