Programming Interactivity, 2nd Edition

Chapter 4. Arduino

The word Arduino refers to three separate tools, which, bundled together, create the toolkit that we refer to as Arduino. First, there is the Arduino controller, which exists in several forms, from large to small to a freely available schematic that anyone with the requisite knowledge can assemble. Second, there is the language and compiler, which creates code for this microcontroller, and which, much like the Processing language, simplifies many of the tasks that challenge designers and developers alike when working with hardware and physical interaction. Finally, there is the Arduino programming environment, which, again like the Processing IDE, is a simple open source IDE built in Java. Therefore, because the word Arduino can have several meanings, I’ll be quite specific when referring to a particular aspect of the environment, such as the Arduino language. When I simply refer to Arduino, I’m referring to the environment as a whole.

So, with that established, what is Arduino? It’s a goal, and that goal is to simplify the creation of interactive applications or objects by simplifying the programming language used to create instructions and by providing a powerful yet basic controller that can easily be used for many common programming tasks while still being robust enough to support more complex projects. The Arduino controller is one of the most remarkable and popular open source projects because it enables so much. Programming microcontrollers can be, to the ...
