Creating a permanent circuit on a printed circuit board

Finishing the project by putting everything into a suitable enclosure

Yogi Berra is alleged to have said, “In theory, there is no difference between theory and practice. But in practice, there is.”

Much of this book is theoretical — how electric current works, how individual electronic components like resistors, capacitors, and transistors work, how digital logic works, and so on.

But the heart of electronics is building things. The reason for learning all the theory is so that you can practice the art by actually building circuits and putting them to use.

Throughout this book, I back up theoretical explanations about how various types of electronic components work with simple construction projects you can build to demonstrate the theory in actual use. In this chapter, you learn the basic construction techniques needed to build these projects.

Specifically, you learn how to create a prototype of a circuit using a handy device called a solderless breadboard. Then, you learn several techniques for creating a more permanent version of the circuit, in which the components and all the circuit’s interconnections are soldered together on a circuit board. Finally, you learn how to enclose your circuit board in a project box or other enclosure.

In this chapter, I walk you through the process of building a fairly sophisticated electronics project. Although you’re welcome to do so if you wish, I don’t expect you to actually build the project as you read this chapter. Instead, I simply want you to gain an appreciation for the process of building a nontrivial project from start to finish.
