Sound sensitive LED baseball cap #WearableWednesday

Nice LED hat from Andrew Staroscik!

This is my first foray into wearable electronics. It is a sound activated hat. There is a microphone below the bill of the hat that picks up the voice of the wearer as well as ambient noise. The sound is converted to light using a small board sewn into the back of the hat. The light patterns in the animated image to the left are random flashes triggered by sound. The intensity of each flash varies with sound level.

Most of the material used was purchased from Adafruit. The microphone is their MAX4466 microphone amplifier. The controller is a an Adafruit Gemma, and the lights are NeoPixel digital RGB LED’s on a strips. The LED’s are individually addressable which makes it possible program very complex patterns using just one pin on the Gemma board. I chose the randoms flashes for this project, but more informative light responses to sound could be used. In fact, after I completed this project, I found a very similar sound responsive baseball cap on Adafruit’s website. The sound/light relationship in their project shows a more informative equalizer pattern.

Electret Microphone Amplifier – MAX4466 with Adjustable Gain: Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn’t nearly as noisy or scratchy as other mic amp breakouts we’ve tried! Read more.

Adafruit NeoPixel Digital RGB LED Strip – White 30 LED – WHITE: You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! These NeoPixel strips have 30 digitally-addressable pixel LEDs per meter and are very affordable and are only 12.5 mm wide, 10 mm if you remove the strip from the casing. Read more.


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!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
