Troubleshooting a button box I bought online
I bought an Arduino based button box with an LED flag box, but the button part of it isn't working. I don't want to say the brand or store, so I don't create any bad press, especially since I've been emailing them back and forth, trying to fix this problem, and they genuinely want to help make it work, but nothing has helped so far. Wondering if anyone has any experience with this type of device.
The problem is, one button is always on, except if some other buttons are pressed. Half the other buttons / toggles don't work at all. The LED flag box works fine, though.
I took pictures of the interior, and he says it seems to be connected correctly. We also re-flashed the firmware, but no luck.
At this point, I think the only thing left, is to request a refund, but wondering if there's anything else I could try first.
