How keypad works & How to scan them?
The working principle is very simple. Pressing a button shorts one of row lines to one of column lines, allowing current to flow between them.
Keypad pins are divided into 2 groups: row and column.
The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot.
