Hello. I am having an issue with my Arduino registering multiple inputs from a single button press. I am trying to setup a button box for my sim racing rig. Now as I have since discovered after completing my project build that the Mega boards do not support HID from factory and require a work around…

Found this very helpful video which answers my initial question. Thanks to some of you for the help. https://youtu.be/GrO8ZmxbOyI?si=SQwOEKPFK2rNxxCU

oh.. Are these all errors that would cause my mulitple inputs detected issue? My full current code: #include <BfButtonManager.h> byte clockpin[] = { 40, 44, 48, 52}; // "clock" pin array byte datapin[] = { 38, 42, 46, 50}; // "d…

[image] b_darr: mulitple inputs detected Your code in post #8 compiles, but the buttons are registering as "pressed" even when not pressed or connected. How are your buttons wired? The Wokwi shows them as shorting geound to pin.

One side of all the buttons are grounded in groups, I am using 3 of the ground Pins on the board, and the other goes to its own unique pin.

[image] b_darr: One side of all the buttons are grounded Yes, but your button is wired as a straight short to the pin. Use diagonal legs on the button to ensure a normally-open button.

So the buttons I used on my actual project are only 2 pin buttons. Wowki doesn't have any 2 pin buttons [image]

haha, yes. So the encoders and push buttons all work in the IDE, but because I didn't know the mega board wasn't a good choice for a gamepad device, I've been trying to use the UnoJoy, specifically the MegaJoy portion of that download, to get everything working as a gamepad

Let us know how the "diagonal legs" in Wokwi goes.

So in Wowki, using the diagonal pins on the button works in that demo. However, my issue is that on a gamepad tester site or the built in windows controller setup, one button press, whether it's a push button or the buttons from the encoders, the tester shows multiple buttons are being read. Also th…

Remove all the encoder code from your sketch and remove the encoders from your board. Connect only your buttons to yiur board. Write code to read and debounce your buttons ONLY when an action occurs, that is to say, only print PRESSED X or RELEASED X one time. You need to have full control of your …

Use diagonal legs on the button.

Are these the same encoders you declared bad last week? Need help using multiple 5 pin rotary encoders
