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.

Getting weather data from Yahoo


For the first project in this chapter, we are actually going to learn how to grab weather data from the Yahoo Weather service. We'll see that it is really easy thanks to Temboo:

  1. First, go to the following URL:

    https://temboo.com/library/Library/Yahoo/Weather/GetWeatherByAddress/

  2. As it's your first time using Temboo, you will need to create a new "shield" for the Temboo service. Don't worry, I know we are not using an Arduino shield here; at the time this book was written, Temboo just didn't support the ESP8266 Wi-Fi chip.

    The best we can do is to select the Wi-Fi shield for Arduino, which is very close in terms of software. Inside the same screen, also enter your own Wi-Fi network SSID and password:

    This will allow you to not have to re-enter those parameters every time. You should now see your newly created shield on the same page:

    Now, we are going to see how to automatically generate the code for our project. We'll then just need to slightly modify it for our...
