GPIO MUSIC BOX

Build a very custom button to

prank your friends

We could very easily lie here, without any

reservations, that the reason we like this

tutorial is because of the ingenious, DIY

button that makes up a major part of it.

However, it’s mainly just an excuse to make a

digital whoopee cushion, which is hilarious.

To be fair, we do also like the very DIY button

made out of paper plates and tin foil and

clips, and it’s a great way to learn how you can

bodge together your own buttons and sensors

and such, while also pranking your parents,

siblings, friends, roommates, or even your boss.

Bring your code into the real world

Coding is fun, but have you ever used Python

code to interact with real-life objects? Using a

simple push-button hooked up to the GPIO pins of

a Raspberry Pi, you can control the way code runs.

In this project, you’ll learn how to program with

a push-button so that specific button presses will

play different sounds.

This project makes use of both GPIO Zero – a

library specifically created to make accessing

components on GPIO easy – and Pygame, which can

be used for programming video games in Python.
