Some updates...
I have made a warning panel for the A2A comanche cockpit:
-Stall warning. If stall warning circuit breaker jumps, it won't switch on
![Smile :)](./images/smilies/icon_smile.gif)
-Push to test button
-Dimmer. Day and night position. With two pots you can set the brightness you want for day and night position.
-Oil pressure
-Low vacuum. So I think I wont make a suction gauge.
-Gear. It blinks if on ground and switch up. Or more than 150knts and switch down. Or flying and throttle less than 10 percent.
-Fuel Pump.
Green if switch on and working.
Red if switch on and not working (circuit breaker jumped).
-Pitot heat.
Green if switch on and working.
Red if switch on and not working (circuit breaker jumped).
Nothing works if low bus voltage.
Everything 3d printed, and working with arduino.
I will put a video.
