# CircuitPython Sound Box
## Overview

## DIY Switches for Assistive Tech – Big Button Audio Sound Box
In this guide you'll learn how to build an Audio Sound Box using Circuit Playground Express and CircuitPython. This device can play back short audio clips and features a really big arcade button that lights up when you press it. It’s a pretty simple project but it’s very useful for the assistive tech community. Similar products are actually quite pricey so a DIY solution can be cost effective, and of course this is customizable!
## Prerequisite Guides
If your new to electronics and the _Adafruit Circuit Playground Express_, I suggest you walk through the following guides to get the basics. The CircuitPython guide will walk you through setting it up.
- [Welcome to CircuitPython](../../../welcome-to-circuitpython?view=all)
- [Adafruit Circuit Playground Express](../../../adafruit-circuit-playground-express)
- [Collin's Lab: Soldering](../../../collins-lab-soldering)
## Electronic Components
The Circuit Playground Express, massive arcade button, PAM8302 amplifier and speaker are the main electronic components used in this project.
