Challenge 1: Examining the Hardware

Abstract

And here we are at Chapter 3, ready to get our hands on an Arduino so we can build something. But what will we make? We’d like to tell you you’ll be building a highly technical computer system that will control a rescue shuttle that will zoom in and rescue Elle and Cade. But like any skill you pick up in your life, the key to success is starting slow and simple. Our first task will be to figure out what hardware we’ll use to build the gizmo that will get Cade and Elle out of the room in which they’re trapped. It’s not a complicated gizmo, however, as you’ll soon see. As a matter of fact, most of the heavy work to get Cade and Elle out of the room will be done in Chapter 4 after you’ve built the gizmo. Then, and only then, will you learn a bit about the sketch you’ll need to create to make your gizmo work properly. All in good time. For now, let’s take a look at the short list of hardware you need to build the gizmo that will free Cade and Elle.
