If you move the motor using the potentiometer it will stay in the position you set it in, instead if you use the joystick it will move and then reset itself in the position chosen with the potentiometer.
I did this because a project with only a potentiometer or only a joystick would have been boring, if you are a boring person you can still use only 1 of the 2 and the code stays the same.
I just realized my circuit images are horrible.
In this circuit I show you the potentiometer version, you can replace it with the joystick just by connecting the red wire to 5v, the blue one to GND and the green one to the x or y axys pin; you could also use both the joystick and the potentiometer at the same time by connecting them both to A0.
