Jeremy Morgan wrote a great post on his site about how to get started with Adafruit IO:
Earlier this year Adafruit Industries put their IoT dashboard Adafruit.IO into Beta, and it looks pretty cool. I’ll show you how to set up a dashboard using one of my mini weather station designs for data input. You may remember this project from a few months ago. I’ll be adding yet another endpoint to the project on Adafruit.IO.
