Internet of Things with ESP8266

By: Marco Schwartz

Overview of this book

The Internet of Things (IoT) is the network of objects such as physical things embedded with electronics, software, sensors, and connectivity, enabling data exchange. ESP8266 is a low cost WiFi microcontroller chip that has the ability to empower IoT and helps the exchange of information among various connected objects. ESP8266 consists of networkable microcontroller modules, and with this low cost chip, IoT is booming. This book will help deepen your knowledge of the ESP8266 WiFi chip platform and get you building exciting projects. Kick-starting with an introduction to the ESP8266 chip, we will demonstrate how to build a simple LED using the ESP8266. You will then learn how to read, send, and monitor data from the cloud. Next, you’ll see how to control your devices remotely from anywhere in the world. Furthermore, you’ll get to know how to use the ESP8266 to interact with web services such as Twitter and Facebook. In order to make several ESP8266s interact and exchange data without the need for human intervention, you will be introduced to the concept of machine-to-machine communication. The latter part of the book focuses more on projects, including a door lock controlled from the cloud, building a physical Bitcoin ticker, and doing wireless gardening. You’ll learn how to build a cloud-based ESP8266 home automation system and a cloud-controlled ESP8266 robot. Finally, you’ll discover how to build your own cloud platform to control ESP8266 devices. With this book, you will be able to create and program Internet of Things projects using the ESP8266 WiFi chip.

Summary


In this chapter, we saw how to use everything we learned so far in this book to build a project you can use in your home: a cloud-controlled door lock. We saw how to control the lock from anywhere in the world, and also how to make the project send notifications automatically to your smartphone when the lock is opened.

There are many ways to improve this project with what you learned in this chapter. One way is of course to add several locks to the same dashboard, and control them all from anywhere. You could also add a timer function to the project, and have the door open automatically between given time intervals (for example for a cleaner to come in).

In the next chapter, we'll see how to use your knowledge about the ESP8266 Wi-Fi chip to build another cool IoT project: a physical Bitcoin ticker.
