Sketching in Code

In the last chapter, we managed to get our first sketch up and running with the famous Blink sketch, otherwise known as the “Hello world” example. This is often a good place to start because it has a long-standing tradition as the first program to write when learning a new language. In the case of programming hardware, we generally use the LED to blink hello. While that is a good beginning, we want to quickly get to some of the more interesting aspects of Arduino C, beginning with the focus of this chapter: the fundamental mechanics and control structures of sketching Arduino code. Our first project, RGB Blink, will explore the basic structure, syntax, and functions necessary for controlling the output of ...
