Adafruit IO Plus Plan Upgrades Are Here!


One of the most consistent requests we’ve had since we launched IO Plus (IO+) was for a way to raise the IO+ account limits even further.

We’re happy to announce that with an Adafruit IO+ subscription, you can now add data rate and storage time limit upgrades!

Library Update: Adafruit IO Arduino

If you have a shiny new piece of Adafruit WiFi AirLift hardware and want to use it with Arduino – you’re in luck! The Adafruit IO Arduino library has been updated to v3.1.0, including an update for using AirLift boards (such as the PyPortal or Metro M4 WiFi Lite) or breakouts.

Grab the new release from the Arduino Library Manager or download it from the Adafruit GitHub.

New IOT Hardware from Adafruit

Adafruit’s new WiFi boards have arrived. Both of these boards come with AirLift – our witty name for the ESP32 co-processor – and are compatible with both Arduino and CircuitPython. All AirLift boards can also connect to Adafruit IO.

Adafruit AirLift – ESP32 WiFi Co-Processor Breakout Board


Give your plain ol’ microcontroller project a lift with the Adafruit AirLift – a breakout board that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite microcontroller (like the ATmega328 or ATSAMD51), awesome peripherals and lots of libraries. But it doesn’t have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if it’s using the latest TLS/SSL encryption (it has the needed root certificates pre-burned in). This breakout includes a crypto chip, too!

Want to pick one up? Visit the Adafruit Store!

Adafruit Metro M4 Express AirLift (WiFi) – Lite


Give your next project a lift with AirLift – our witty name for the ESP32 co-processor that graces this Metro M4. You already know about the Adafruit Metro M4 featuring the Microchip ATSAMD51, with it’s 120MHz Cortex M4 with floating point support. With a train-load of FLASH and RAM, your code will be fast and roomy. And what better way to improve it than to add wireless? Now cooked in directly on board, you get a certified WiFi module that can handle all your TLS and socket needs, it even has root certificates pre-loaded. Since this is a lite version of the AirLift module, it has a 8MB flash and no crpyto chip.

Low Cost Internet Enabled Voltage and Current Logger


Darian Johnson “needed a low cost way to measure current requirements and battery drain over time” for one of his wearable projects. He also had a “TON of Adafruit Feathers and FeatherWings, so [he] decided to use components [he] already had, plus an Adafruit INA219 FeatherWing to build a voltage and current logger which logs to SD card and Adafruit IO

Smart HDMI Switcher with Adafruit IO and IFTT


Scriptmonkey_ on twitter did a bit of hacking this past Easter weekend connecting their HDMI switcher to the internet. To avoid the remotes piling up on their coffee table, or getting up from their couch, they used an ESP8266 connected to an Amazon Alexa over If-This-Then-That to voice-control their TV’s inputs.

Adafruit IO Raspberry Pi Cloud Camera Tutorial

Interested in sending different types of data to Adafruit IO? IOTDesignPro published a very detailed tutorial for streaming the camera’s images (as data) from a Raspberry Pi using MJPG-streamer over the internet to an Adafruit IO Dashboard.

Mini IOT Display with PushBullet Notifications


Labsud built a Mini Connected Display to show messages received from an Adafruit IO Feed using a EspressIf WeMos D1 Mini and a ST7789 TFT display. They also set up IFTTT to display notifications from their smartphone to their display with Adafruit IO’s IFTTT integration.

Multi-Sensor IoT Environmental Sensor Box With CircuitPython


This guide will walk you through making an environmental monitoring device with GPS, Temperature, Humidity, Barometric Pressure, and Air Quality sensors, all updating to the cloud. Once build, this project takes readings occasionally and sends them to Adafruit IO, stamped with time and location. All that is required is an AC outlet and a WiFi network.
