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.
