Adafruit IOT Updates
MQTT comes to CircuitPython!
So, you have a CircuitPython project and want to connect it to the internet? You may want to consider adding MQTT to your project. MQTT is an extremely popular and lightweight protocol which can connect your project to the internet and quickly process network events. We’ve built a robust MQTT module for CircuitPython called CircuitPython MiniMQTT to quickly get you started connecting your projects to the internet and sending data around. Learn all about using MQTT with CircuitPython in on the Adafruit Learning System Guide here!
Adafruit IO CircuitPython Library UPDATE: MQTT!
The Adafruit IO CircuitPython library has been updated with a new IO_MQTT class for accessing Adafruit IO’s MQTT Broker. We’ve included helpful methods for simplifying interactions with Adafruit IO over MQTT. Download the latest version of the Adafruit IO CircuitPython Library in the CircuitPython Bundle here and check out some examples which make use of the new MQTT class here.
New IoT Hardware: 8-Channel LoRa Gateway HAT with LoRa and GPS Antenna
This LoRa HAT from RAK Wireless is capable of multi-channel, multi-node communication, all running in a non-intimidating, hackable Raspberry Pi environment. Unlike our basic LoRa gateway bonnet, this chipset can support all 8 channels, so it can handle multiple clients, on different LoRa channels, without having to do any code tweaks. Visit the product page fo the LoRa Gateway HAT here! Once you have your Internet-to-LoRa gateway set up with this kit, make LoRa nodes using our Feather line for easy deployment of sensor networks that run on battery power. We have guides about setting up LoRaWAN nodes using either Arduino OR CircuitPython on the Adafruit Learning System here.
#ComingSoon IoT Hardware: Circuit Playground Express BlueFruit
We are testing the Circuit Playground Express BlueFruit, check out the coming soon photos. We went to Washington Square Park at night to test how far we could change the colors of the NeoPixels on the CPX Bluefruit and we’re going to need a bigger park to test in maybe 🙂
Interactive Airplane Sculpture, beautiful and internet connected
“The Imagination Machine” has been my main focus for a little over 9 months. I’m thrilled to see it in such a grand space. As you may read in the articles, it tracks the ISS using the NASA open API + Adafruit.io + IFTTT. It keeps time using the RTC. It also has some other codes onboard that I’m developing that will use more of NASA’s API (tracking near earth orbit asteroids, etc.) I had always intended for the piece to make a connection from country to country as well. At the moment, I’m currently on an artist residency in Dresden, Germany. It’s ongoing exploration includes allowing my new friends here in Germany to say “Hello” to the sculpture in Ohio from my phone. Using using the Adafruit.io and my phone, they can trigger a special light show that connects two different cultures located an ocean apart - Adafruit Blog
Issue 21 HackSpace magazine: Air quality monitor
The new HackSpace Magazine Issue 20 highlights an air quality monitor build using a Raspberry Pi 4 and air quality sensor. The project is programmed in Python 3 with the Adafruit Adafruit IO data service (free at io.adafruit.com) holding data and providing status - Adafruit Blog
Analog Smart Shelf
Jake P. on HackADay.io is building “A sleek and minimalist wall-mounted shelf with hidden wireless charger and customizable wooden display”. Unlike most smart-assistants, it’s designed to be unobtrusive - HackADay.io
Tweeting with CircuitPython
This guide shows how to use the Twitter API to get tweets from a specific user (but there’s a lot more you can do with it). As a concrete example, it will be used to regularly fetch the the latest tweet from @codewisdom, a feed that tweets quotes from the software industry. We’ll take those tweets and display them on a PyPortal - Adafruit Learning System
Using WoTT to manage your Adafruit IO feeds!
Web of Trusted Things (WoTT) published an guide about using Adafruit IO with their WoTT Secure Agent, an open-source solution designed to manage your credentials (such as your static Adafruit IO username/active key pair) - Web of Trusted Things
