On Control Board

Wire Red wire to 2+ or 1+

Wire Black Wire to 2- or 1-

The control Board must go into RPI USB to power servo, but also for programmability.

It is possible using PC Firmware to switch to Manual Mode, but change is permanent, and I think not worth it.

I have seen Linux utils that can switch from 4 way to 8 way from Python script sending command over USB. Use this.

We can add GUI commands, etc for this.

We are supposed to only connect Common-ground and Normally Open.

This makes it go from off to pressed as expected.

If we wired Normally Closed instead of Normally Open Pressing the button would change Pressed to Not Pressed. In other words the circuit would default to closed as if we always pressed button. Do not use this.
