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.

Sending an e-mail notification

It's now time to make our first project: sending e-mail notifications! For this first approach to notifications, we'll simply send a message at regular intervals to the e-mail address of your choice.

To connect the ESP8266 to IFTTT, we need a channel called Maker, which is available on IFTTT. You first need to go to the Channels tab and find this channel:

Once the channel is opened on your screen, you need to connect it to your IFTTT account:

This will allow you to get a key for your Maker Channel:

Make sure you have this key to hand; you'll need it really soon. As for all channels, you only need to do this once.

The next channel we'll add is the Email Channel:

Here, enter the e-mail that you will use to receive the test messages coming from the IFTTT server. Make sure to put your own e-mail, otherwise it would be considered spam.

Then, we can create a recipe that will link the Maker Channel to sending an e-mail. Simply click on the following button on the main page...
