Inspired by the Ablenet Big Mack, this DIY version uses the Adafruit Circuit Playground to play sound, light up neopixels and even function as a USB mouse clicker. The code was written by Limor Fried in Circuit Python, so it’s easy to build on top of using Adafruit’s libraries. A PAM8302 audio amplifier and a 3W speaker provide decent volume and its adjustable with a potentiometer. Check out the guide for full list of build materials, source files and code!
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!

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
