I am just thinking about to build an FCU for aerosoft airbus. I can use arduino for toggles and buttons with Linda. I can also use potantiometer for such as flaps, trim etc via FSUIPC. But I dont have any idea what should I use for hdg-alt-spd select. I can assign buttons for them in Linda but It would be good to use potantiometer for realism. 

 

Thanks.

Instead of potentiometers you could use rotary encoders for the FCU.

These can rotate an infinite amount while potentiometers can only rotate a fixed range.

very true, the originals in a real plane ARE rotary encoders. If you dont wish to order some (Desktop Aviator has them real cheap) you can get them out of old car radios, some keyboards and even toys. Just make sure they turn continuously and dont have stops. Otherwise, If setup properly - to auto repeat - you can fit either a 3 position Rotary or SPDT with center off switch to a keyboard mapping to allow you to increase or decrease the setting. again however you would need a keyboard emulator card to do so (or wire it to a keyboard if you feel daring)

 

Other than that - you have to have an IO board to interface them. There are many sources for those, some are mostly for switches/buttons but have the encoder ability as an addon, lol.

 

I'm curious tho, what is LInda? While my 3d printer is Arduino based I have never had an opportunity to use it as a hobby controller, is Linda part of that?
