GEMMA and CircuitPython: More Adafruit Learning System Updates

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:

A NeoPixel Blinkendisc — Customize a Flashflight or other suitable flying disc, and throw blinky programs at your friends.

Light-Activated Pixel Heart — Wear your heart on your sleeve! Or at least on your lapel. This light-up heart display uses a light-dependent resistor and GEMMA, Adafruit’s tiny wearable electronics platform.

NeoPixel Tiara — You can make a crown of light for prom or your birthday this year! A few free-wired NeoPixels make you the cyber-pageant queen.

LED Masquerade Masks — Got a costume ball coming up? Learn to adorn masquerade masks with LEDs, three ways! This guide will show you how to make three masks at different difficulty levels: Super Simple Sequin Mask, NeoPixel GEMMA Mask and Audio-Reactive Mask.

Trinket / Gemma Mini-Theramin — Snuck a Trinket guide in there! But this project works equally well with GEMMA. Make music with tiny microcontrollers and varying light levels.


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.
