With this chapter, we finish our journey through the Arduino platform, but even in this last chapter, we have met some new components such as the relay.

Once again, we have seen the importance of a modular design when developing these kinds of projects and how much the code benefits from such an approach.

I'm sure that with all that you have learned in this book, you will be ready to develop your own Arduino-based projects and that you will have developed your own ideas for projects while you read this book.

So, don't put this book too far away from your working desktop, so that you can use it as a reference and begin to enjoy working on all these projects by yourself.
