Chapter 8. Controlling a Door Lock from the Cloud

This will be the first project of this book in which we'll take everything we learned so far and integrate it to make a complete Internet of Things project you can actually use in your life.

For this project, we are going to build a door lock that we can control from anywhere on the planet using the ESP8266 Wi-Fi chip. We are also going to see how to integrate notifications right into the software you'll build, so you will receive a push notification in case anyone opens the door lock. Let's start!
