Button Box

Not sure if this is the right forum but I have a button box using a matrix and whenever i have certain buttons on and press ones it turns on others. So if I have 6+9 on and press 4 it turns on 4 and 1. Any help or advice? Not sure if maybe I've coded it wrong.

I have no clue if you are coding it wrong because you have not posted your code.

Hey mate, welcome to forum. I highly encourage you to read the rules. You should post your code and try to explain what you are trying to do (in a not so encryptic way).

Thanks

Did you write a simple test sketch that does absolutely nothing except register the button presses?

how do you drive and power the "matrix" ?
