NEW TUTORIAL: Manually bridging MQTT to Adafruit.IO

I’m going to start this off by admitting something up front. I didn’t build this the right way. Well, let’s mellow that a little and say I didn’t build this in the most optimal way. Sometimes you already have some infrastructure in place beyond simple networking and when you tinker with new sensors you just use the infrastructure you already have. Then later, when you want to extend your project from tinkering to the cloud, you have to jump through some hoops to make it work. If you want to skip what I actually did and just read about how I should have done it, just click on “The Right Way to Have Built This!” on the left side navigation bar.

So, on with the project! I bought one of the then-new Adafruit GA1A12S202 log-scale light sensors to tinker with (it’s been around for a while now). At the time, I was teaching myself Lua so I could program the ESP8266 using NodeMCU. What a perfect project, I thought! I’ll use the Feather Huzzah 8266 and the light sensor to record the light levels. At this point, I wasn’t thinking about Adafruit.IO, I was just thinking of grabbing some light level data.

Skip forward to this morning when I woke up at 1:05 AM and couldn’t get back to sleep. “I should hook that sensor platform up to Adafruit.IO,” thought I. And I got to work. This tutorial talks about how I did what I did. Oh, and yes, it does work.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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 code.org, 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.
