Gemma + Neopixel Bow for Grace Hopper Celebration #WearableWednesday

Cute bow project from electronatom on YouTube.

I made this Neopixel ring bow that uses a Gemma microcontroller from Adafruit to light up this fun accesory with cool, reprogrammable patterns! It was a hit at #GHC15, with many fellow and budding makers coming up to geek out with me over Arduino, electronics, and wearables 🙂

I’ve soldered snaps onto the Gemma pads to make it easy to snap it off this circuit and use in another creation! I also made almost everything modular by using Velcro for the battery and the flower on top.

NeoPixel Ring – 16 x WS2812 5050 RGB LED with Integrated Drivers: Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75″ (44.5mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you’re ready to rock. Read more.
