I’d like to welcome you to the second episode of our new series of videos and guides, designed to help you learn about and make your very own connected objects This is Adafruit and Digi-Key’s ALL THE INTERNET OF THINGS – a six-part series, covering everything you need to know about the Internet of Things (which we will shorten to IoT). For our second guide, we’ll go over the most popular protocols used in the IoT industry, as well as the upsides and downsides of each type of protocol to help you decide what you’ll use to connect your devices to the internet and exchange data. In TRANSPORTS we talked about – “How to Get From Your Device to the Internet” – POWER, DISTANCE, AND BITS.
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.
