Summary

Whew! That was a lot to get through for our first project, but we made it! We started with the philosophy of sketching in code; introduced our first project, including some diagrams and source code; discussed the structure of Arduino C, including using comments, the basics of Arduino functions, and working with statements and the elements of syntax; and then we wrapped things up by looking at compiling, saving, and uploading our sketches, as well as some common errors that might crop up once in a while.

That should have provided a nice overview of what goes into your typical Arduino sketch and given you a sense of how these various parts work together. It’s really not that bad and the more you work with it, the easier it gets. Now before we get to some of the more advanced digital and analog functions available on the Arduino, we need to first cover a few more basics in the next couple of chapters. We will begin by revisiting our RGB Blink sketch from this chapter to see what we can do with it, while also talking about variables and the different kinds of data types available to us. Hang in there, I promise it’ll get much more interesting once we get these basics out of the way.
