PieterP:
Again, I can't help you if you don't post your exact code and complete error messages.
after putting the code that you sent me,
the potentiometers worked .. I wanted to connect the slider pot too.
but there is a problem .. when I attack one it works with two also .. when i attack the third no longer goes and if I move the first one also moves the third .. I tried everything, I also remade the connections and tested individually slider ... I do not know how to move on
thanks
