I was clearly inspired by this project by Phillip Burgess. But I wanted to build a more robust solution for cars, with 8 channels. I never designed a PC board before, so that was a fun learning experience. I had the PCBs manufactured, bought a ton of parts, and I am now putting these kits together. I can also sell a parts-kit and the blank PCB for anyone that wants to build it all themselves. As the original post mentions, this can be used for wearables, cosplay, toys, games, Halloween, or really anything that needs remote activated sound effects.

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.
