SOME END OF YEAR STATS!


Stats

In early 2019, we posted up our CircuitPython 2019 post, and soon we’ll have a CircuitPython 2020 post which will have a recap of what we’ve done together as a community and where we might be going. We’ll include a few stats in the 2020 post, and we wanted to have a post with a BUNCH of stats as well – here we go!

CLUE

Coming soon, our latest CircuitPython powered board, CLUE! Here’s a bit more, and the TOP SECRET video – YouTube:

“We wanted to build some projects that have a small screen and a lot of sensors. This board has a 1.3″ 240×240 IPS TFT display, two buttons, and a ton of sensors: LSM series 9 DOF motion, APDS9960 light/color/proximity, PDM microphone, humidity, temperature and barometric environmental sensing. There’s a QWIIC/STEMMA QT connector for adding more sensors like PM2.5 air quality and others that were too big to fit on the board. We’ll be primarily using CircuitPython for programming it, but it will also work in Arduino. And of course, we’d love to see MakeCode on it! After designing it, the board was close enough to micro:bit-shape-size that we moved a few parts to make it fit in micro:bit robots and some projects – the nRF52840 chip is a big upgrade and it can do stuff like Tensorflow lite for microcontrollers, BLE central and peripheral, and more.”

Hackster.io has some coverage as well.

Program in Python with LEGO EV3

LEGO

Follow up, looks like this is now live – Python for EV3:

“You can now use your EV3 Brick to unleash the power of Python programming using MicroPython. Simply install the EV3 MicroPython image onto any micro SD card and boot up your EV3 Brick from it to start programming straight away. Switching back to the standard LEGO® MINDSTORMS® EV3 firmware is just as simple. We have also provided full documentation and sample API code to get you started.”

Call for help – CircuitPython messaging to other languages!

Hello world

We have 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.

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.
