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.
