Button Box Wiring Help

[ecstaticbrick]

Edit: Please ignore this or can a mod delete this post. The answer is NO it won't work and is almost completely wrong :-(

I have removed the images so that no one copies it and get it so badly wrong like I did. Sorry.


Hi all, I need a bit of help.

I got bored and thought I would try my hand at building a pro micro button box but, I have never had any experience with wiring matrix' before. I know there are tutorial videos out there but they skip parts that seem obvious but, they really aren't.

I have planned out what I think is correct but, could someone with experience look over my pictures and let me know if it will work or do I need to make changes.

Any help would be appreciated.

Have a look in my thread (http://forum.projectcarsgame.com/sho...x-input-wanted). I used a buttonmatrix, total 5 rotary encoders, and maybe 16 buttons. There´s both pictures and the code I used.

Don't remember much of the details now, but feel free to ask any questions you have. There are no stupid questions

Thanks for the link. I actually had some one explain it to me by voice and it made more sense. I don't no why but, I had it in my mind that I could wire positives in parallel and the negatives in parallel but still being in groups but, the arduino code wouldn't have worked for that and I don't know enough about writing a custom code... Yet :-)

Just got to practice soldering and I will post again if I get it to work.

@ecstaticbrick Arduino isn't that difficult to code. I build a button box for flight sim with it. It's some typing effort, but the logic behind it, is pretty straight forward.

Shepard2603, that might as well be Esperanto to me lol

Maskmagog, did you use solder? I'm struggling with it :-(

[Maskmagog]

Yes, solder. I'm an old sound engineer so I'm used to soldering. Get as decent equipment as you can. Watch some youtube videos, plenty of tutorials. Have patience, and practice

[COBaker]

I had the same problem exactly a year later, probably it occurs more often in winter, judging by the practice. I asked my father to help me because he is well versed in this field, but he was in another city and could not come. He gave me the contacts of service to find the best electricians in my city and they helped me to solve this problem, as they said it was in the violation of the current supply and most likely the reason for this was water although I do not remember that I drowned it, hehe. However, after that, the problem disappeared and did not occur again
