Overview of this book

The ESP8266 Wi-Fi Module is a self contained System on Chip (SOC) with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This book contains practical recipes that will help you master all ESP8266 functionalities. You will start by configuring and customizing the chip in line with your requirements. Then you will focus on core topics such as on-board processing, sensors, GPIOs, programming, networking, integration with external components, and so on. We will also teach you how to leverage Arduino using the ESP8266 and you'll learn about its libraries, file system, OTA updates, and so on. The book also provide recipes on web servers, testing, connecting with the cloud, and troubleshooting techniques. Programming aspects include MicroPython and how to leverage it to get started with the ESP8266. Towards the end, we will use these concepts and create an interesting project (IOT). By the end of the book, readers will be proficient enough to use the ESP8266 board efficiently.

Automation with IFTTT

If This Then That (IFTTT) is an online service that allows users to create simple conditional statements called applets. The applets are triggered depending on changes made on or to other web services. For instance, you can set an IFTTT applet that sends you an e-mail if a user includes a certain hashtag in their tweets. You can also configure an applet that saves all the photos that you have been tagged in on Facebook to a cloud server such as Google Drive.

In this recipe, we will look at how to use the IFTTT online service to automate IoT projects. We will use it to publish data to different online platforms, just like Temboo. To demonstrate how to do that, we are going to publish temperature data from a DHT11 sensor to Twitter, using an ESP8266 board.

Getting ready

You will need the following hardware components:
