Challenge 4: Examining the Hardware

Abstract

So far, you haven’t been working with complex systems of circuitry, but you’ve been building a foundation for using circuitry with the Arduino. But things are about to change, and some of the gizmos you’re going to create will be a bit more involved in terms of building and programming. But that’s a good thing! You’re learning more and more about the Arduino and how other electronic components work with it, plus you’re delving deeper into the programming aspect of gadget design. At this point, you’ve definitely moved beyond Arduino novice, and you should congratulate yourself on that. We also hope you’re beginning to look around and ask questions about how exactly things work in your world—the lights, the computers, and even the vehicles and machines that these days all have electronics inside them. Your Arduino and electronics skills will continue to improve if you always ask questions and look for answers, and your status as an Arduino guru will become a certainty.
