Hello everyone, I am new to this world of programming, I might know how to use it with Mobiflight and arduino mega2560 to use the spoiler lever, either with a potentiometer or with micro swich I have already configured with mobiflight and arduino, the landing gear lever and the led and everything is perfect, but I can not manage to assign the spoilers nor with what element I can do it either with a potensiometer or with a micro swich
If someone could help me solve my problem I would appreciate it
I have tried to configure with Arduino mega 2560, as it says a tutorial of mobiflight assigning as joystick in arduino but I get an error when wanting to validate the code that fasilitan in the tutorial, the code is this:

//Create Joystick
Joystick_ Joystick;

Be sure to download the Joystick library from https://github.com/MHeironimus/ArduinoJoystickLibrary

Here is the full code to copy and paste.

#include <Joystick.h>

// Create Joystick
Joystick_ Joystick;

unsigned int xAxis = 0;
unsigned int yAxis = 0;
unsigned int zAxis = 0;

// Set "initAutoSendState" to true for "Auto Send" mode or false for "Manual Send" mode.
const bool initAutoSendState = true;

void setup() {
Joystick.begin();
}

void loop() {
xAxis = analogRead(A0)/4;
xAxis = map(xAxis,0,255,-127,127);
yAxis = analogRead(A1)/4;
yAxis = map(yAxis,0,255,-127,127);
zAxis = analogRead(A2)/4;
zAxis = map(zAxis,0,255,-127,127);

Joystick.setXAxis(xAxis);
Joystick.setYAxis(yAxis);
Joystick.setZAxis(zAxis);

//Joystick.setState(); //this updates the "Joystick" library
//and therefore your computer of all the current
//joystick and button states determined above
//all at once. YOU ONLY NEED TO USE THIS LINE
//IF const bool initAutoSendMode = FALSE (the
//code for the initAutoSendState is a few
//lines above the "setup" section of code.
}

but wanting to load it I get this error:

Arduino:1.8.7 (Windows 7), Tarjeta:"Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Hi... Welcome to Mobiflight !

You mix up different things !

Mobiflight basicly NOT support potentiometers ! ( At the moment.... Maby in future but this is not a feature that is high priority for us... maby it comes maby not)
So if you like to work via Mobiflight you need to do this with Microswitches.... BUT Spoilers basicly work steppless ... so a Potentiometer is more relistic.
With a Microswitch logic you can build maby just something like OFF-ARM-FULL ... That work But again thats not like real !
(Microswitches are good for Flaps Leaver but not work for Throttle or a realistic Spoiler leaver ! )


About Pottis.

As i said.... With Mobiflight ( And with a Mega that is used as Mobiflight Board .... So after flashing MF Firmware) there is no possibility to use potentiometers!

The Script you quote ( By MHeironimus ) is just for Arduino Micro and Leonardo. It will not work for with MEGA or UNO .... Simply cause it need a Microcontroller that is shown as a HID Controller for Windows . For Mega and Uno this is not possible... Just by rework the Main Mega Code ( By Bootloader) . But again then the Memory size is a Problem i think.
As i know it is NOT possible to use this code on a Mega finaly... Only a older version that not iclude so much Pins !

Whatever.... If you use THIS code then you can not use the same Board via Mobiflight same time !!! ( This script overwrite the MF Firmware ! )

*****
Solution :

For Potentiometers at the moment the only way is to use a Joystick Controller !
1. A Real one like a LeoBodnar BBI32 (Expensiv)
2. A reworked Arduino with Heronimus Script (Note you need a Micro or Leonardo for this)

Finaly i recommend here to work with a Registred Version of FSUIPC ( If you work on FSX/P3D) .

Then the Potentiometer is controlled by the Joystick Controller Board.... And is show as a real Axis like "Joystick Nr 5 Axis X".
Finaly you can set this axis in FSUIPC ( Or in your AddOn Settings) to a function like "Speedbrakes" .

Thank you very much for your response and expansion of the information, I already feared it! , I get more complicated work, without having much programming knowledge, well, I will try in another way to see what I resolve, and thank you very much for your time
