  6. Vertical potentiometer
  7. +5VDC
  8. GND
  9. -5VDC


The joystick potentiometers work by voltage division between -5V and +5V. Actually, it uses a couple of resistors on each side to make it more like -3.4V to 3.4V.

All voltages are taken with respect to ground

The buttons are normally open type, and close circuits to ground when pressed.
