The ESP8266 is an amazing little chip which has onboard WiFi capabilities, an integrated processor, and also comes at less than $10.
This makes it the perfect chip for DIY electronics projects, and especially in the home automation field. There are many breakout boards available for the ESP8266, but in this guide we are going to use the Adafruit HUZZAH ESP8266 breakout, which is a very convenient ESP8266 breakout board.
In this project, we are going to use the ESP8266 to build two components which are very useful in home automation: a sensor module, and a lamp controller.
We are also going to link these two projects to Adafruit IO, which will allow you to control this small home automation system from anywhere in the world. Let's start!
