The Internet of Things! The Internet of Things! THE INTERNET OF THINGS! OK now that I’ve got your attention, lets talk about this INTERNET OF THINGS (IoT). IoT is this idea that, hey – my toaster! my car! my dog’s collar! – all those things can be connected to the Internet and each other.
Adding connectivity can make projects and products a lot more useful and fun. And if you’re a developer, engineer, hacker or maker, this tutorial will delve deeper into the details of protocols and libraries!
In particular, we’ll be focusing on MQTT (MQ Telemetry Transport).
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
