Preface
In this book, I have tried to include something for readers with various skill levels and interests. It contains hardware projects, software projects, and a combination of both. In all cases, I have tried to begin with a simple project and moved on to progressively harder and more complex projects. Depending on your skill level, some projects will take an hour or so to build and some will take longer.
Either way, I hope you will enjoy building the projects as much as I have enjoyed writing about them.
