I'll start by saying I know very little (and I mean little) about wiring and all of the hardware. It's very possible what I have done so far is completely wrong, but I hope I at least have some of it right.
I've found out about the button matrix looking around online and managed to make one of my own. Although I didn't quite get it right with the wiring. I believe I recognize the problem but I don't know how to deal with it.
I loaded up the code that I downloaded from a yt video and only had to change a few things to get it right with my matrix. Tested it on the pc game controller, and everything seems to work fine, except for two toggle switches.
My On-off-on toggle switch (can be pushed up or down but always reverts back to center pos) only works when I push up on the toggle. I was wondering what I need to do to make pushing the button down work.
Im also wondering How to wire a non led rocker switch up, and how to find or implement a code for this.
Thank you for your time, it's appreciated.

. I'll read into it some more and When I get home I will play with it some more. May just be in way over my head.
