Learn how to connect your shiny new ESP32-S2 CircuitPython projects to the internet using MQTT. The CircuitPython MQTT Library, MiniMQTT, has been updated to support the ESP32-S2 so you can connect boards such as the Adafruit MagTag or Adafruit Metro ESP32-S2 to the internet!
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.
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.
