Internet of Things with Arduino Cookbook

Overview of this book

Arduino is a powerful and very versatile platform used by millions of people around the world to create DIY electronics projects. It can be connected to a wide variety of sensors and other components, making it the ideal platform to build amazing Internet of Things (IoT) projects on—the next wave in the era of computing. This book takes a recipe-based approach, giving you precise examples on how to build IoT projects of all types using the Arduino platform. You will come across projects from several fields, including the popular robotics and home automation domains. Along with being introduced to several forms of interactions within IoT, including projects that directly interact with well-known web services such as Twitter, Facebook, and Dropbox we will also focus on Machine-to-Machine (M2M) interactions, where Arduino projects interact without any human intervention. You will learn to build a few quick and easy-to-make fun projects that will really expand your horizons in the world of IoT and Arduino. Each chapter ends with a troubleshooting recipe that will help you overcome any problems faced while building these projects. By the end of this book, you will not only know how to build these projects, but also have the skills necessary to build your own IoT projects in the future.

A cloud-controlled digital candle


In the previous recipe, we learned how to build a digital candle using Arduino. But what about the IoT aspect of the project? Well, this is what we are going to deal with in this recipe. We are going to connect the project from the previous recipe to the cloud, and learn how to control it from anywhere. This could, for example, be a candle that you send to loved ones that are far away, and that you suddenly switch on to show you are thinking about them.

Getting ready

For this project, first you need to follow the previous recipe to build the candle. Then, you can configure the candle with some new code to control it from the cloud.

You will need to install the PubSubClient and aREST libraries, which you can easily do by using the Arduino library manager.

The sketch starts as always with the required libraries:

#include <SPI.h>
#include <WiFi101.h>
#include <PubSubClient.h>
#include <aREST.h>
#include <Adafruit_NeoPixel.h>
#define...
