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.

Dim LEDs from anywhere in the world


You have probably already seen those LED strips that you can control remotely. We are going to do the same in this recipe (with three LEDs of different colors), but in this project you'll be able to control those LEDs from anywhere in the world.

Getting ready

For this recipe, you are going to need three LEDs of different colors (I used a blue one, a red one, and a green one). For each of those LEDs, you will also need a 330 Ohm resistor.

To assemble the project, first place all the LEDs on the breadboard, with each one of them connected in series with a resistor, the longest pin of each LED connected to the resistors. Then, connect all the free pins of the LEDs to the GND pin of the Arduino board. Finally, connect free pins of the resistors to Arduino pins 3, 4, and 5.

This is the final result:

How to do it...

We are now going to configure the board. As the sketch is nearly the same as the previous recipe, I will only highlight the main differences here.
