Hello, I was looking at this 4x4 keypad membrane and I was curious as to how one would even go about reading this thing? I have no datasheet for it but after a search over the web, it seems to be an extremely common keypad.
"Standard" matrix keypad. Tutorial here:

The "datasheet" is actually one of the 2 images on that page.
Thank you!
