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.

Automated M2M with IFTTT

In this recipe, we will look at how to use IFTTT for your M2M projects. To do so, we will use IFTTT to send data from one ESP8266 board to another. This is going to be facilitated by the IFTTT maker channel and an MQTT broker. We will use the Adafruit IO MQTT broker in this recipe.

Getting ready

You will need the following hardware components for this project:

  • Two ESP8266 boards

  • Two USB cables

  • 220 Ω resistor

  • LED

  • Momentary Push button

  • 10 kΩ resistor

The setup will resemble the one in Basic local machine to machine interaction of this chapter. We will have one ESP8266 board setup with a Push button input and the other with an LED output.

Install the Adafruit MQTT library. To do that, search for adafruit mqtt in the libraries manager and select the first result:

You will also need an IFTTT account at and an Adafruit IO account at You can refer back to Chapter 6, Interacting with Web Services for details on how to use IFTTT.
