CircuitPython Day Celebrations!

CircuitPython day celebrations

Thank you everyone out there who celebrated CircuitPython day! We’re catching up on all the activities and more over the last week, last weekend, and what’s ahead. Here we go!

CircuitPython Day 2019 Code + Community = CircuitPython <3


“This year we at India Linux User Group -Delhi (ILUG-D) and Hardware Hacker’s club – Delhi decided to introduce CircuitPython to our local community members of Delhi, India and there was no better day to do this than the official Circuitpython day itself. Though the official day was on 8-8-2019 (being the most snakey day), we celebrated in on 4th Aug since it was a weekend.”

Changing Lives through Open Source, Passion and Mentoring

Changing Lives through Open Source, Passion and Mentoring

For CircuitPython day Kattni, Ladyada, and Scott talked about the recent keynote at PyOhio: Changing Lives through Open Source, Passion and Mentoring by Kattni – YouTube.

“In trying to learn Python, I stumbled into a passion I had never considered. My path began with learning Python on hardware. Through mentorship and the help of friends, I began to flourish. Since then I have continued to contribute in ways I never thought possible, between code, community, and becoming a mentor myself. This is the story of my journey and how mentorship can change lives.”

FEATHER takes flight with the Wio Lite W600 from Seeed Studio

Wio Lite W600

FEATHER takes flight with the Wio Lite W600 from Seeed Studio – Adafruit.

Wio Lite is a new product line from Seeed, and Wio Lite W600 is the first product in this series. Similar to the great Adafruit Feather series, the Wio Lite series is small in size and uniform in pins. Different performance and features are available when equipped with different processors and modules. Actually, Wio Lite is compatible with Feather board pins, we believe Feather is a very successful development platform in the community, and there are already many cool Feather boards out there from Adafruit. The Wio Lite aims at adding different wireless solutions to enrich the Feather community and provide more possibility for Feather users. On top of that, we’ve released the Grove Shield for Wio Lite at the same time. With this shield, we bring over 200 Grove sensors, actuators and displays to Wio Lite series and the Feather community.”

And check out AWESOME-FEATHER, a curated list of awesome Feather form factor boards, guides, videos, libraries, software and resources.

PyDev of the Week: Raphael Pierzina on Mouse vs Python

Made with Mu – PyperCard


PyperCard – Easy GUIs for All – pypercard.readthedocs.io. PyperCard is a HyperCard inspired Pythonic GUI framework for beginner programmers. PyperCard makes it quick and easy to create software with a modern user interface to use on your Windows, OSX, Linux, Android or iOS devices. PyperCard was created in response to the work of the wonderful folks at Adafruit who designed a simple GUI library for one of their CircuitPython based devices. PyperCard takes Adafruit’s original concept, refines it and makes it available on a large number of computing platforms. To achieve this, PyperCard currently uses the Kivy UI framework under the hood.

Check it out! All in Mu!

Why Mu? Mu tries to make it as easy as possible to get started with programming but aims to help you graduate to “real” development tools soon after. Everything in Mu is the “real thing” but presented in as simple and obvious way possible. It’s like the toddling stage in learning to walk: you’re finding your feet and once you’re confident, you should move on and explore! Put simply, Mu aims to foster autonomy. Try out Mu today! – codewith.mu

Updated Guides – Now With More Python!

You can use CircuitPython libraries on Raspberry Pi! We’re updating all of our CircuitPython guides to show how to wire up sensors to your Raspberry Pi, and load the necessary CircuitPython libraries to get going using them with Python. We’ll be including the updates here so you can easily keep track of which sensors are ready to go. Check it out!

Keep checking back for more updated guides!

CircuitPython Libraries!

CircuitPython Libraries

CircuitPython support for hardware continues to grow. We are adding support for new sensors and breakouts all the time, as well as improving on the drivers we already have. As we add more libraries and update current ones, you can keep up with all the changes right here!

For the latest drivers, download the Adafruit CircuitPython Library Bundle.

If you’d like to contribute, CircuitPython libraries are a great place to start. Have an idea for a new driver? File an issue on CircuitPython! Interested in helping with current libraries? Check out this GitHub issue on CircuitPython for an overview of the State of the CircuitPython Libraries, updated each week. We’ve included open issues from the library issue lists, and details about repo-level issues that need to be addressed. We have a guide on contributing to CircuitPython with Git and Github if you need help getting started. You can also find us in the #circuitpython channel on the Adafruit Discord. Feel free to contact Kattni (@kattni) with any questions.

You can check out this list of all the CircuitPython libraries and drivers available.

The current number of CircuitPython libraries is 171!

Call for help – CircuitPython messaging to other languages!

Hello world

We posted on the Adafruit blog about bringing CircuitPython messaging to other languages, one of the exciting features of CircuitPython 4.x and above is translated control and error messages. Native language messages will help non-native English speakers understand what is happening in CircuitPython even though the Python keywords and APIs will still be in English. If you would like to help, please post to the main issue on GitHub and join us on Discord.

We made this graphic with translated text, we could use your help with that to make sure we got the text right, please check out the text in the image – if there is anything we did not get correct, please let us know. Dan sent me this handy site too.



jobs.adafruit.com has returned and folks are posting their skills (including CircuitPython) and companies are looking for talented makers to join their companies – from Digi-Key, to Hackaday, Microcenter, Raspberry Pi and more.

Codecademy “Learn Hardware Programming with CircuitPython”

Codecademy CircuitPython

Codecademy, an online interactive learning platform used by more than 45 million people, has teamed up with the leading manufacturer in STEAM electronics, Adafruit Industries, to create a coding course, “Learn Hardware Programming with CircuitPython”. The course is now available in the Codecademy catalog.

Python is a highly versatile, easy to learn programming language that a wide range of people, from visual effects artists in Hollywood to mission control at NASA, use to quickly solve problems. But you don’t need to be a rocket scientist to accomplish amazing things with it. This new course introduces programmers to Python by way of a microcontroller — CircuitPython — which is a Python-based programming language optimized for use on hardware.

CircuitPython’s hardware-ready design makes it easier than ever to program a variety of single-board computers, and this course gets you from no experience to working prototype faster than ever before. Codecademy’s interactive learning environment, combined with Adafruit’s highly rated Circuit Playground Express, present aspiring hardware hackers with a never-before-seen opportunity to learn hardware programming seamlessly online.

Whether for those who are new to programming, or for those who want to expand their skill set to include physical computing, this course will have students getting familiar with Python and creating incredible projects along the way. By the end, students will have built their own bike lights, drum machine, and even a moisture detector that can tell when it’s time to water a plant.

Visit Codecademy to access the Learn Hardware Programming with CircuitPython course and Adafruit to purchase a Circuit Playground Express.

Codecademy has helped more than 45 million people around the world upgrade their careers with technology skills. The company’s online interactive learning platform is widely recognized for providing an accessible, flexible, and engaging experience for beginners and experienced programmers alike. Codecademy has raised a total of $43 million from investors including Union Square Ventures, Kleiner Perkins, Index Ventures, Thrive Capital, Naspers, Yuri Milner and Richard Branson, most recently raising its $30 million Series C in July 2016.
