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.
In this guide, you will set up your CircuitPython board with the necessary libraries, connect to the internet and connect your CircuitPython board to either a MQTT broker of your choice or the free Adafruit IO MQTT broker. We’ve included code-walkthrough and advanced usage sections to this guide so you can roll your own MiniMQTT project!
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.
