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.

Controlling the LED from a cloud dashboard

It's nice to be able to control an LED from your web browser, but what we really want is to be able to control it from a nice graphical interface, from anywhere in the world.

This is exactly what we are going to do in this section, by using a service called the aREST dashboard. We will actually use it not only to control the LED, but also to dim the LED using a slider, right from your browser.

If it's not been done yet, create an account at:

You should be able to create a new dashboard from the main interface:

Now, inside the dashboard, we are going to create a new element to control and dim the LED.

Create a dashboard element of the Analog type, and also insert the ID of the device you want to control. Also don't forget to set the pin to 5:

You should instantly see the newly created element inside the dashboard:

Now, try the slider that you just created:

You should notice that whenever you move this slider and release the mouse...
