his Adafruit 1×4 Membrane Keypad

has four input buttons, each with

its own wire for hooking up to your

project. And since all of the buttons

are wired individually, you don’t even

need a microcontroller to use it. Use

it in your next project just like any simple button or

switch. The membrane has a soft touch, and it can

easily be mounted by removing the paper backing,

exposing a strong adhesive. Adafruit includes a

5-pin, extra-long header strip so you can easily plug

it into a breadboard.

Tactile inputs

Adafruit also sells a larger version of its membrane

keypads if you need extra inputs. It’s a similar hook-up

process, and is just as easy to get up and running

thanks to Adafruit’s online tutorials and projects. Just

keep in mind, this version will require a microcontroller.
