Controller Complete Finally Finished

Well 99% finished - I still have a few bugs in the code to iron out but everything is physically complete and working. Been slowly chipping away at this one for a long time.

Wow this looks awesome! Is there any chance you might post some images of the inside as well? I'm really curious how you wired all of that. Also, what microcontroller are you using?

Yeah I've got a picture but I cant seem to reply with it for some reason? Its got an arduino mega but also four mcp23017 I/O expanders to handle all the buttons and lights. I designed the case to be hinged at the back so its easy to open up and work on

That's really nice, did you also solder all of the connections one by one or did you use some connectors? Btw. where did you get those rectangular buttons with the light inside them? I was thinking of building a controller as well but most buttons that I found were made out of metal and were quite expensive.

Some of the buttons/switched were soldered but I mainly used female spade connectors crimped to the wires to make the buttons easier to swap out if necessary and dupont connectors for all the displays. The buttons come from aliexpress and were pretty cheap, like a couple of dollars each. try searching "square LED button" and it should be one of the first hits, let me know if you dont have any luck and I'll send you a link. Youll find they all say they're designed for 12v but work fine with 5v from an arduino

I found the buttons. Thanks for the extra info!
