Matrix keyboard

Overview

A matrix
keypad is a common input method for electronic devices. It uses a special matrix row and column arrangement to detect and input keys.
A matrix keypad consists of a set of keys (usually buttons or switches) and a matrix circuit. Essentially, it uses 8 I/O ports to control and read 16 keys, thus reducing the number of I/O ports used.
