One of the great things about the Raspberry Pi is how everyone starts with same piece of gear. Since the audio hardware is identical on every unit it is trivial to load the drivers and play mp3 files.
This guide describes how to connect input buttons and play audio files using a Raspberry Pi. We make use of the Adafruit’s Pi Cobbler Breakout Kit and the python module RPi.GPIO. If you have not already used the raspberry pi as a input device this guide will show you how to wire the pull-down resistors, GPIO pins and buttons.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
