First of all, great project! Congratulations!
I'm building the B737 Throttle Quadrant v3. For now printing the 3D parts and preparing the connections and I found an incongruity / difficulty. About the STAB TRIM in the construction video, two on/off switches are installed. However it's said that they must have three positions, on/off/on which is what is on the shopping list. Now seeing the wiring diagram for the arduino micro pro (I will install it on the arduino micro), I see that there are only two on/off connections.
The questions are as follows:
- The B737 has two guards for these switches, which will give three positions that would be: ON - MAIN ELECT/AUTOPILOT = NORMAL, OFF - MAIN ELECT/AUTOPILOT = guards open and ON - MAIN ELECT/AUTOPILOT = OUT. Is this correct?
- If so, how to connect and affect these switches to the simulator (P3D)?
Another question is simpler and related to Parking Brake, and they are the following:
- The Parking Brake lever has two microswitches. Only one is in the wiring diagram, ON/OFF and is assigned to the PB. Will the second be for the light?
I dare to suggest that there could also be a scheme for the Arduino Micro that seems more applicable to this project.

I believe the second microswitch is just for a detent position, its not wired to anything.
After see the video again yes, you are right, the second microswitch is only for detent. I will try modify the PB leaver to have the second microswitch to light and detent.
With arduino micro led is possible. About FSUIPC, how to configure de reverse axis without Prosim B737? It´s possible use the 3 stages?
I'm not sure why the online build guide suggests on/off/on toggles. The pdf guide uses simple on/off.
I used on/off, then configured FSUIPC to control both the switch AND the guard when I move the toggle (I'm using the PMDG aircraft)
The second microswitch is just there to provide the notch detent.
I think Karl runs the light off an external feed from a Mobiflight Arduino Mega.
What I've done is connect the light between the Micro Pro vcc and the input to the microswitch. Only downside is that the park brake light stays on even if the battery master is off, but I can live with that (and you should have the wheels chocked and the park brake off at that point anyway)
