Adafruit IoT Monthly – March 2019 #adafruitio #IoT

Welcome to the Adafruit IOT Monthly for March 2019. This newsletter (in blog form) highlights projects and updates about Adafruit IO – our Internet-of-Things Service for makers, news, stories, and advances in the world of IoT.

Adafruit IO News: Features and Updates

IO News highlights what’s new on Adafruit IOour internet-of-things service for makers.

Adafruit IO for CircuitPython

Adafruit IO has landed on CircuitPython. The CircuitPython Adafruit IO library makes interacting with the powerful Adafruit IO API simple. We’ve included support for interfacing your CircuitPython board with a ESP32 coprocessor over either SPI or UART.

Check out the library on GitHub – we’ve included lots of examples for using this library to interact with Adafruit IO and CircuitPython.

New Adafruit IO Hardware – PyPortal

PyPortal, is our easy-to-use IoT device that allows you to create all the things for the “Internet of Things” in minutes. Make custom touch screen interface GUIs, all open-source, and Python-powered using tinyJSON / APIs to get news, stock values, weather, cat photos, and more – all over Wi-Fi with the latest technologies. Create little pocket universes of joy that connect to something good. Rotate it 90 degrees, it’s a web-connected conference badge #badgelife.

IO Update: New Line Chart and Gauge Rendering

Adafruit IO – our Internet of Things service –  just received a behind-the-scenes upgrade. In order to reduce the amount of Javascript we send to your browser every time you visit Adafruit IO and in order to fix an annoying memory leak bug, we’ve replaced the rendering engines for the gauge and line charts you see on your Adafruit IO dashboards and feed pages. They’re low-level updates to the Adafruit IO website you all use. For the most part the changes should be invisible, but we wanted to at least mention it in case they take you by surprise.

Powered by Adafruit IO: Projects from the Community

Each month, we select our favorite projects from around the internet which use Adafruit IO. Here are some of our favorites:

Monitoring a board’s power consumption over the internet

Groguard is using two Feather-compatible Giant boards to send power consumption data to Adafruit IO for real-time visualization (and possibly long-term logging). Instead of using a multimeter, he’s using a INA219 DC current sensor to monitor current draw over I2C.

Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here:

Join Adafruit on Mastodon

Adafruit is on Mastodon, join in!

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, 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.
