Joystick Math

Some explanation about +Y to +Y and -Y to +Y outputs:

1. positive voltage on Y input appears on "+Y to +Y" output while "-Y to +Y" output remains at zero Volts
2. negative voltage on Y input appears inverted (positive) on "-Y to +Y" output while "+Y to +Y" output remains at zero Volts

This splitting allows two functions control by one axis, one for positive joystick movement and second for negative movement, on both outputs from 0V to positive voltage.
This can be used for any input voltage (for example splitting sine to two outputs=two half-waves, both outputs positive)
