LED Bracelet Reacts to Music #WearableWednesday

Marcus Olsson loves to hack and he’s been creating a series of LED bracelets that we have been following. His first one was motion activated, but his latest version is a VU meter. That means it is party ready! You can make one, too, because he has posted his work and code here on Slickstreamer.

The 3D printed bracelet uses a Trinket, mic, power switch and Neopixel strip. After gluing things in place, he added a bit of foam to keep the mic protected. It’s a tight squeeze, but Marcus made sure to enlarge the 3D print design to account for the mic addition. One of my favorite parts of the build is his use of small magnets to snap the cover in place.

He’s done another great job and he even has another use for the bracelet — a camping or beach lamp! Now he just has to add a citronella dispenser and he’ll be able to repel bugs.

The code Marcus hacked was mainly from our Ampli-Tie Learning Guide. So, why not follow in his footsteps and learn about NeoPixels and mics. You’ll have something special whether you’re seen clubbing or camping.


Flora breadboard is 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!


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
