HackSpace magazine Issue 30: 8 ways of building an Internet of Things #IoT #InternetOfThings @HackSpaceMag @AdafruitIO

Issue 30 – HackSpace Magazine writes about eight ways to build your ideal Internet of Things (IoT) network.

Many Arduino-compatible boards can connect to the internet in some way, but in order to make them useful, we need something for them to communicate with. Fortunately, there’s a wide range of tools for you to use to make this easy. Here, we look through our eight favourite IoT back-ends that we can use to make our online Arduino projects really useful.

#1 on their list is Adafruit IO, Adafruit’s Internet of Things service.

Adafruit IO is an online service that allows you to store bits of data that come from, or should go to, your
internet-connected devices. It’s based around the concept of streams of data. Each stream is a sequence of bits of information that could be numbers, text, or other things. Each is associated with the time it’s added, so you can, for example, log the temperature as a stream of numbers representing the degrees Fahrenheit. On top of this, Adafruit IO has dashboards which each include widgets that can either read data from a stream and displaying (such as a line graph or gauge), or send data to a stream, such as a button you can click on and off.

There are libraries for Arduino and CircuitPython to help you send and receive data. The free plan lets you create ten feeds and five dashboards with data stored for 30 days, but if you upgrade to pro (for $10 per month), you get unlimited feeds and dashboards with data stored for 60 days.
