The two potentiometers indicate which direction the potentiometer is being moved. The switch sends low (or ground) when the joy stick knob is pressed. This module produces an output of around 2.5V from X and Y when it is in resting position. Moving the joystick will cause the output to vary from 0v to 5V depending on its direction.
