Hello everyone. I have a problem with my Arduino Mega 2560 and my rotary encoder YK040. I clarify that I use the default Cessna 172 with FSX. When I connect the first rotary encoder, the Arduino and the FSX receive it perfectly. The problem comes when I connect the second, or the third, Arduino does not read it. When I activate the first one, the TX light turns on, with the rest that does not happen. The connections are well made, and the configuration in Mobiflight too. I use the mobiflight 7.5.2 last one.
Thank you

KY040 requires 5v supply. How did u wire these encoders?

Standard Procedure.....

1. Check on a neutral ground .
Not use difficult or sepcific configs ( where the config itself can have a issue) Use ONE Config for testing ( in a clear file) and make something verry easy.
For example only use ON LEFT and ON RIGHT ( Not work with on fast) . Use KEYSEND for both and write "A" for left and "B" for Right.
Then Start Sim, Mobiflgiht and a Textprogramm like "Wordpad" . Open a flight, Minimize the Sim Window, Start Mobiflight RUN Button and klick on the Textprogramm Cursor.
NOW a turning from Encoder will write A or B like you press the buttons on the keyboard.

Check now ALL Encoders with this config ( Simply swap the Device after you test one to the next encoder. )
Benefit is simple.... You can exclude a issue in the config 100%

2. Check electrical Setup
As thatchi said.... KY040 need 5v power . ( Thats why i recommend to use basic encoders 3 Pins instead those difficult PCB Encoders like Ky040)

3. Check Device Settings in Mobiflight. Every Encoder must be a own device..... On Own 2 Pins ( not used by something else) .
Also make always a restart of Arduino and Mobiflight after you make a change ( Like Upload Devices)
Good Luck !
