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.

Troubleshooting basic M2M issues


In this part of the chapter, we are going to see what can go wrong when building M2M projects using Arduino.

Pushing the button doesn't do anything

The first thing that can happen is that the button is not correctly wired to the Arduino board. Make sure that you followed the wiring instructions. You can also check the lights on the Arduino board when you press the button: a light should turn on whenever the board is sending data, so this is what you should see when pressing the button.

The pump/sprinkler doesn't get activated

One simple reason for this problem is that the humidity doesn't get low enough for the board to send an alert. What I recommend doing is checking the humidity level with the test sketch of the sensor. If needed, adjust the thresholds inside the code to make the board send correct alerts depending on the level of humidity you want for your plants http://www.kasetophono.com/2014/10/night.html.
