Michael Klements | Connect A 4x4 Keypad To One Arduino Input @MichaelKlements | Uploaded April 2020 | Updated October 2024, 56 minutes ago.
In this Tutorial video, I'm going to be showing you how to connect a 4x4 keypad to a single Arduino analogue input. A 4x4 keypad is a really useful Arduino project component, particularly for security access projects or projects requiring code inputs. These keypads typically require 8 IO pins in order to function. This tutorial only uses one, enabling you to free up more of your IO for sensors, displays, motors and servos and allowing you to build more complex projects.
