This guide will show you how to send button press data to Adafruit IO from the HUZZAH ESP8266, then use that data to change the color of an LED connected to a second HUZZAH ESP8266.
If you haven't worked your way through the Adafruit IO feed and dashboard basics guides, you should do that before continuing with this guide so you have a basic understanding of Adafruit IO.
You should also go through the setup guide associated with the HUZZAH ESP8266 for use with the Arduino IDE.
If you have completed all of the prerequisites listed above, you are now ready to move on to the Adafruit IO setup steps.
Let's get started!
