xbox 360 macro controller for fifa14

Hello there everybody, my name is Herman and this is my first post. There is a football match-up called FIFA 14 on the xbox360 that you may have known about, in this game you can do abilities where you move the joysticks around and it does expertise. The issue is that the joysticks work by having 2 potentiometers to control this and to the extent I realize they can't handle obstruction with an Arduino. I need to make a regulator that has an independent chip to press different catches and.
The second thing is I was searching and found some digital potentiometers and was wondering if anyone knew how to use them with an Atmel chip. So essentially I'm saying would I be able to utilize digits rather than simple pots?

Thanks
