Internet of Things with Arduino Cookbook

By: Marco Schwartz

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.

Controlling your robot from anywhere


To end this chapter and this book, we are going to integrate our mobile robot into the Internet of Things, and learn how to control it from anywhere in the world. We'll learn how to call the function we defined earlier from anywhere in the world, and then how to control the robot using a cloud dashboard.

Getting ready

For this final recipe, you just need to have followed all the previous recipes in the chapter.

How to do it...

As the code for this recipe is really similar to the code from previous recipes, I will only highlight the main differences here. You can, of course, refer to the GitHub repository of the book for more details.

You need to include the following libraries:

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

Then, an important point here is to define a unique ID for the robot:

char* device_id = "40ep12';

This will basically identify your robot on the aREST cloud. Then, inside the loop...
