Well, if you get the pot's installed, then you won't need limit switches, as they should be able to tell you how far you have rotated and in which direction. The pot's themselves get connected to the analog inputs, and I believe you need to use something like Get_Analog_Value to actually get sensible data from them. I can't check right now, because I just shut down the computer with all my code on it.

If you do a search for pot's, you should be able to find more detailed help on them
