Summary

In this chapter, we explored all manner of ways in which the Arduino can alter the standard top-to-bottom program flow using various methods to make decisions and perform repetitive actions. You should have a basic understanding of how to make decisions using conditional statements and how to perform repetitive tasks in iterative statements, or loops. Of course, we will continue to work with these concepts in later discussions, building out from our foundational understanding of how we can structure Arduino sketches. But for now, that about wraps up the discussion of the generally more C-based structural programming syntax.

From here, we will discover more of the uniquely Arduino aspects of programming the Arduino microcontroller board that specifically relate to sensing and controlling the physical world. These are the parts of the Arduino library that make Arduino C unique. This is going to be the really fun stuff.
