Even More GEMMA CircuitPython Guides

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’re 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 175 GEMMA-related guides in the Adafruit Learning System, watch for updates in small batches. Here are the latest:

Remember to remember. This Mindfulness Bracelet will alter your perception of time through gentle vibration queues. This project is a great way to start using transistors and vibrating motors.

These stunning 3D Printed LED Fire Horns will liven up any event. A NeoPixel ring or stirp can be inserted inside each horn. The code provided is quite advanced in that it provides high quality fade waves with gamma correction.

Bright, bright, bright Mini Basketball Hoop lights! This project has a simple version which is “always on”. It will run through various rainbow patterns and color wipes. The more advanced configuration using an IR LED and IR sensor to detect when a ball passes through. The hoop will illuminate for two seconds when a point is scored. If you are getting into detecting movement this is a great project to start with.
