Adafruit’s new GEMMA M0 wearable microcontroller comes with CircuitPython support fresh from the factory. Plug it into USB and use any text editor to open and edit the “.py” file…it’s just that simple, no IDE to install!
We’ll be updating most of our “classic” GEMMA guides on the Adafruit Learning System to provide example CircuitPython code for the new board along with the original Arduino sketches, and bringing the latter up-to-date where needed. GEMMA M0 can run either one.
With something like 160 GEMMA-related guides in the Adafruit Learning System, watch for updates in small batches. Here are the latest:
3D Printed NeoPixel LED Gas Mask — It’s got hints of Star Wars, Fallout, and Guardians of the Galaxy. It’s got lasers, EL wire and of course, NeoPixel LEDs. In this project, we’re mounting glowy electronics to some 3D printed parts to light up your face!
Space Face LED Galaxy Makeup — Wear some space on your face and be a constellation for Halloween! This galaxy makeup is inspired by the Cassiopeia constellation and uses five FLORA NeoPixels to light up the night sky across your forehead, affixed with liquid latex. GEMMA and a coincell battery back reside on a hair clip and run the pixels in any color you choose.
NeoPixel Punk Collar — Get your cybergoth on with five color-changing NeoPixels studded onto a leather collar. The tiny GEMMA microcontroller can display endless animations on this fun funky accessory that’s easy to make with a little soldering!
3D Printed Unicorn Horn — Searching for a simple costume project to bring your Unikitty or Lady Rainicorn to the next level? 3D print a flexible unicorn horn and illuminate it from within with NeoPixels and a GEMMA microcontroller. Or forget the electronics and use glow in the dark NinjaFlex filament for a green glow with no batteries required.
Jewel Hair Stick — This Japanese-style hair ornament combines an upcycled chopstick with felt, embroidery, beads and a GEMMA microcontroller. A NeoPixel Jewel provides the real beauty with kaleidoscopic flower designs.
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.
