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.

Hardware configuration

We are now going to assemble the different parts of this project. First, we are going to configure the motion sensor module. For this first module, after placing the ESP8266 board on the breadboard, connect the VCC pin of the sensor to VCC, GND to GND, and finally the OUT pin of the sensor to pin number 5 of the ESP8266.

This is the final result for this module:

Hardware configuration

Let's now deal with the temperature and humidity module. Place the sensor on the breadboard, and then connect the first pin to VCC, the second pin to pin number 5 of the ESP8266 board, and finally the last pin of the sensor to GND.

This is the final result for this module:

Hardware configuration

Let's now assemble the LED dimmer module. Here, we are going to use a simple LED as the output, but you can of course use this as the starting point of a module to control more LEDs in your home, or even lamps.

To connect the LED to the ESP8266, simply place the LED in series with the 330 Ohm resistor on the breadboard, the longest...
