ESP8266 Internet of Things Cookbook

By: Marco Schwartz

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.

The ESP8266 chip is a powerful and cheap microcontroller with an onboard Wi-Fi connection. It is also very easy to use, thanks to the compatibility with the Arduino IDE. Therefore, it's just the perfect chip to build the Internet of Things (IoT) projects.

Inside this book, we'll see how to build IoT projects using the ESP8266, via several step-by-step tutorials. At the end, you will know how to use all the functions of the ESP8266, and you will be able to build your own projects with this amazing Wi-Fi chip.

What this book covers

Chapter 1, Configuring the ESP8266, will be about getting started with the ESP8266, and learning how to configure the ESP8266 and all the hardware/software components that you need to use it.

Chapter 2, Your First ESP8266 Projects, will be about learning how to make your first simple projects with the ESP8266.

Chapter 3, More ESP8266 Functions, will be about learning advanced functions of the ESP8266, as using the file storage system.

Chapter 4, Using MicroPython on the ESP8266, will be focused on using the powerful & simple MicroPython language to build projects with the ESP8266.

Chapter 5, Cloud Data Monitoring, will be about connecting your ESP8266 to the cloud, in order to monitor your projects from anywhere in the world.

Chapter 6, Interacting with Web Services, will exploit the Wi-Fi connectivity of the ESP8266 to connect to existing Web services, such as IFTTT or Google Drive.

Chapter 7, Machine to Machine Interactions, will be about building projects where ESP8266 boards communicate directly with each other via the cloud.

What you need for this book

To build the projects you will find in this book, any experience with programming and/or electronics is of course appreciated, but you will be able to follow even if you have little experience in the field, as we will start from the absolute basics of the ESP8266.

Who this book is for

This book is for people who want to build their own Internet of Things projects, using the ESP8266 as the platform to easily build those projects.

It is also for people already building IoT projects, for example with Arduino, and those who want to discover another platform to build IoT projects.


In this book, you will find several headings that appear frequently (Getting ready, How to do it, How it works, There's more, and See also).

To give clear instructions on how to complete a recipe, we use these sections as follows:

Getting ready

This section tells you what to expect in the recipe, and describes how to set up any software or any preliminary settings required for the recipe.

How to do it…

This section contains the steps required to follow the recipe.

How it works…

This section usually consists of a detailed explanation of what happened in the previous section.

There's more…

This section consists of additional information about the recipe in order to make the reader more knowledgeable about the recipe.

See also

This section provides helpful links to other useful information for the recipe.


In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We will configure pin 5 as an input and then read it using the digitalRead() function and display the state of the input signal on the serial monitor."

A block of code is set as follows:

// LED pin
int inputPin = 5;
int val = 0;

void setup() {
  pinMode(inputPin, INPUT);

void loop() {
  // read pin
  val = digitalRead(inputPin);
  // display state of input pin  

Any command-line input or output is written as follows: --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect 0 esp8266-2016-05-03-v1.8.bin

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The .bin files for the MicroPython port for ESP8266 are under the Firmware for ESP8266 boards sub heading."


Warnings or important notes appear in a box like this.
