DIY Arduino Buttonbox

Thanks
I am attaching the project and sketch

I'm not a programmer. I don't understand shit about sketches, but can get it to work.
I made a wheel with 1 potmeter for clutch and 1 joystick for menu's. (https://www.xsimulator.net/community/threads/diy-arduino-buttonbox.8302/page-10#post-197114)

Maybe you can adjust the sketch?

Ride on
Bakhol

I did not understand you
is it possible to create a sketch as a jpg configuration?

Hello everyone. First of all thank a fellow forum member ((JonBakhol)). For all the help you have given me during my project. Thanks to him, I have learned a little more about how the Arduino world works.
But "Jon" is also human and although we have done many tests, I still have the problem.

I have a 32 button keypad. Here I leave the drawing.

The buttons all work. Windows recognizes the board as a gaming device. Everything is correct, but the buttons do not work well. There are buttons that activate, its corresponding button number, but there are others that activate 2 buttons, other buttons activate 3 buttons. I have reviewed everything and it seems to be fine, the cables correspond to the drawing. There are no cables that are touching each other and make a false connection.
That is why I ask for help, to see if someone else can help me. Greetings to all and thanks.

Hi there, I have been having a play with the project and have a basic understanding of this. I have 3d printed a flight sim cessna trim wheel that uses one rotary encoder. Would anyone be kind enough to put together the sketch for one rotary encoder used on a pro micro and show up as a game controller in windows. I am happy to gift £10 for anyone time on this via paypal to say thank you.

sorry ... it is possible to insert 2 potentiometers in the project, thanks for the reply

I would like to ask if there is anyone who is able to modify the code by adding another potentiometer, unfortunately I am new to arduino ... I have tried but I have not succeeded. thanks to those who want to help me.

Hey, friends, I have a poor experience with an Arduino as well as with micro-electronics in general. I made my button-box by this guide successfully, but I would like to use a button with a 5v indicator so I've been trying to connect It to VCC and GND of my Pro Micro to give the button additional voltage, but as soon as It happened the box became working incorrectly and windows assign a few button positions to one physical button of the box. How I could fix It?

Hello. I am new here and need your help . I downloaded the Buttonbox Sketch from Amstudio. I wanted to ask if anyone can help me change it so that I can connect 2 Hall sensors? Need that for the clutch on the steering wheel. Thank you

I tested as a keyboard on XBOX One and the rotating ones worked perfectly in the Dash console menu, but unfortunately the rotating did not work perfectly in the game, I testedf1 2021. I tried to use the rotarys in fuel adjustment and brake and differential bias but the rotarys worked late and with failures. It seems that the game does not communicate properly with the rotating as well as the Dash console menu. Did you take the ps4 test?

Hi guys, here is the drawing of my button box, I wanted to know if the wiring is good and which library and other I must install on the arduino so that it works with my diagram. thank you

I don't know if my photo is uploaded

New
Could someone give me a hand... I want to load this code on an Arduino micro and it gives me this error

Is that code in Spanish? have you translated it? Those orders and libraries seem to be translated from English to Spanish.

They are the ones I copied from page 10 that the creator put.. I don't understand why it gives me this error

Could you give me a hand... because I get this error like the word joystick has something wrong... I want to load the code into my arduino just as you put it in voice
