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.

Creating a new Facebook post from the ESP8266

In the last project of this chapter, we are going to see how to interact with Facebook from the ESP8266 Wi-Fi chip, via Temboo. We will see how to simply post a status update, but you can use it to post something on a friend's wall, post data on a page, and much more!

  1. The first step is to create a Facebook app. You can do so by going to:

  2. From there, click on Add a New App:

  3. When the interface asks you for the type of app, choose Website:

  4. Then, give your app a name:

  5. You will then be asked for a URL. This doesn't matter (it won't be used by the project), and you can put whatever you wish:

  6. After that step, your app will be created. What you need to get here is the app ID and app secret, which should appear inside the application dashboard:

  7. Then, go to Setting, and find Client OAuth Settings. Add the URL given in this screenshot as a callback URL, by replacing the Temboo username:

  8. You're all set on the Facebook side! Now...
