3 Meet the Circuit

In the last chapter, you learned a bit about the Arduino and its parts. You were also introduced to some of the components and tools you’ll be using to complete the projects in this book. In this chapter, you’ll learn some of the electronics practice and theory you’ll need to know to build circuits using the Arduino. We won’t be using an Arduino just yet, but we’ll get back to that shortly.

The Circuit: Building Block of Electronics

The circuit is the basic building block for all of the electronics projects we’ll be building with the Arduino.

You can build many different types of projects with an Arduino—you are limited only by your imagination. Although many different types of projects exist, all the projects in this book ...
