I always make some sort of light up sunglasses for music festivals and they are always sound-reactive and usually awesome. This is the latest version. I made them using an Adafruit trinket microcontroller (arduino compatible), several neopixel LEDs, a microphone, and my custom PCB that I made in Fritzing.
The code has a lot more Neopixel functions in it, which unfortunately I was not able to fit on the trinket (thinking of changing to the larger trinket pro so I can fit more awesomeness!)
First mode is sound-reactive, second mode is rainbow fade, and third mode is random lights or “Stranger Things” mode 🙂
Adafruit Pro Trinket – 3V 12MHz: Trinket’s got a big sister in town – the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in. Read more.
Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!

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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
