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.

What is Bitcoin?

Before we actually start building the project itself, let's first quickly talk about Bitcoin, in case you don't know what it is yet.

Bitcoin is a virtual currency that emerged back in 2009. Unlike other virtual currencies that existed up to then, Bitcoin is protected by a global network of computers, all working with the same distributed ledger called the Blockchain, which guarantees every transaction made.

Since then, a lot of people and businesses around the world have started to accept Bitcoin as a way of payment. Bitcoin is also accepted in brick and mortar stores; for example, stores that display the Bitcoin Accepted Here sign:

Of course, Bitcoin is also traded on exchanges, and therefore has a price in USD, and in most of the main currencies. For example, at the time of writing this book, one Bitcoin was worth 417 US dollars.

Therefore, it could be quite interesting and fun to make a project to find out how much Bitcoin is currently worth, using the ESP8266 Wi-Fi chip...
