Cool

👍😍

[@FHamoudi]

Thank you for the great video. I bought two of these boards and am excited to use them for a DIY flight sim project. What Arduino board is compatible with these boards?
Keep up the great work.

[@Gigawipf]

Any arduino would be able to read it using the shiftIn function for example. If you want to make it a gamepad you need one with native usb like the arduino micro.

@@Gigawipf Thank you for your swift response, I have a couple of pro micros, so will be using one. The Arduino code you have shared, I am assuming its for a gamepad. Is this the case? Cheers :)

[@Gigawipf]

@@FHamoudi no its not. it is just an example how to read the data. using it as gamepad buttons would be easy if you check out gamepad libraries.

@@FHamoudi Any luck getting this to work m8? could you share some info if so

[@jayare7750]

Would pressing various buttons at the same time be registered adequately or are there limitations as to how many buttons can be pressed at the same time?

[@Gigawipf]

They are all sampled at the same time so you can press as many as you want.

@@Gigawipf awesome, thank you! I am learning to code so I wasn’t sure how many iterations of the binary bits I would have to write to get all combinations, or if there is a way to make it bit dependent, but it looks like OpenFFBoard makes this project so much easier
