"This is a new Module I made this week. It is called an FM JOYSTICK. It has (2) Bi-polar AXIS that act as Attenu-inverters. What the heck is that? Think of it like this----middle joystick is 0v(ZERO). Left and Right is Positive and Negative. So it will inverter what ever you plug into it.
When there is nothing connected to the Input jack of an axis it will internally Switch and supply 2.5v for you to Invert and output. It can be adjusted with a Trimmer inside to about 6.5v if you wanted a greater sweep.
I calibrated the Middle/Zero area on a 12v based Power supply. There are trimmers to calibrate the Zero area.
There is also a push button feature on the Joystick just like the home Gaming Joysticks. There are (2) passive Jacks on the top for you to connect and activate with the Push action of the Joystick.
The joystick has Spring Return to the center."
