I have made this panel to a friend who need it for his cessna 310 simulator.
Arduino... link2fs... and a lot of leds
There are trims indicators (darsonval) and a flaps position. Those are move with motor drivers L298.

The stall warning has a relay activated with arduino with a 12v buzzer.

The vid is in spanish. Im not good enough to speak in english, sorry. But It can be easy understand.

Thanks!
