C Programming for Arduino

By: Julien Bayle

Overview of this book

Physical computing allows us to build interactive physical systems by using software & hardware in order to sense and respond to the real world. C Programming for Arduino will show you how to harness powerful capabilities like sensing, feedbacks, programming and even wiring and developing your own autonomous systems. C Programming for Arduino contains everything you need to directly start wiring and coding your own electronic project. You'll learn C and how to code several types of firmware for your Arduino, and then move on to design small typical systems to understand how handling buttons, leds, LCD, network modules and much more. After running through C/C++ for the Arduino, you'll learn how to control your software by using real buttons and distance sensors and even discover how you can use your Arduino with the Processing framework so that they work in unison. Advanced coverage includes using Wi-Fi networks and batteries to make your Arduino-based hardware more mobile and flexible without wires. If you want to learn how to build your own electronic devices with powerful open-source technology, then this book is for you.

Chapter 7. Talking over Serial

We already saw that using Arduino is all about talking and sharing signals. Indeed, from the most basic component in Arduino, reacting to some physical world values by changing its environment and propagating the change as a basic message to its neighbors, to the now classic serial communication, electronic entities are talking among themselves and to us.

As with the many concepts in this book, we have already used serial communication and the underlying Serial protocol a couple of times as a black-boxed tool, that is, a tool I have introduced but not explained.

We are going to dive into it in this small chapter. We will discover that serial communication is used not only for machine-to-human communication but also for "component-to-component" discussions inside machines. By components, I mean small systems, and I could use the term peripheral to describe them.
