Here’s the amazing part: You can make electronic gadgets that do these things for just a couple of bucks! At the same time that the art and science of electronics is rapidly advancing, the price for building a circuit that can do something incredibly nifty is dropping like a stone. Unless you’re constructing a time machine, or the world’s largest robotic rabbit, the typical home-brewed electronics project costs less than dinner for four at a no-frills restaurant. If you’re looking for a cool hobby, electronics is one of the least expensive ones around.
Oh, and did I mention that electronics is fun?
You may also want to consider this possibility: People who know the practical side of electronics — what things are, how they work, and how to put them together — can find some really great jobs on the market right now. If you’re interested in a career in electronics, make this book your first step to a fun and rewarding new job.
Also, many other hobbies rely on knowledge of electronics in some way. Maybe you’re into model railroading. You can figure out how to build your own automated track switchers. Or perhaps you like racing radio-controlled cars. With an understanding of electronics, you may discover how to improve the performance of your car and beat your best friend in the next race. Knowing more about how electronics stuff works can make your other hobbies more fun.
And, last but not least, electronics is fun. Or maybe I mentioned that already?
Foolish Assumptions
This book assumes that you know diddly about electronics. From the very first chapter, we introduce you to basic concepts that you need to master in order to follow what we say in later chapters. But if you already have a handle on the basics, you can easily jump to a later chapter and dive right in. (If you need to know something really important to keep you safe from something such as electrocution, we provide a cross reference to send you back to the relevant chapter for a refresher course.)

Introduction
3
You can also use the most-excellent table of contents at the front of the book and the index that Wiley has thoughtfully provided at the back to quickly find the information that you need.
Safety Is Number 1
Reading about electronics is pretty safe. About the worst that can happen is that your eyes get tired from too many late nights with this book. But actually building electronics projects is another matter. Lurking behind the fun of the electronics hobby are high voltages that can electrocute you, soldering irons that can burn you, and little bits of wire that can fly into your eyes when you snip them off with sharp cutters. Ouch!
Safety is Numero Uno in electronics. It’s so important, in fact, that we devote an entire chapter of this book (Chapter 2) to it. If you’re brand new to electronics, please be sure to read this chapter. Don’t skip over it, even if you think you’re the safest person on earth. Even if you’ve dabbled in electronics before, it never hurts to refresh your safety memory. When you follow proper precautions, electronics is a very safe and sane hobby. Be sure to keep it that way!
¸ Although we try to give you great advice about safety throughout, we can’t possibly give you every safety precaution in the world in one book. In addition to reading our advice, use your own common sense, read manufacturer’s instructions for parts and tools that you work with, and always stay alert.
How This Book Is Organized
Electronics For Dummies is organized so that you can quickly find, read, and understand the information that you want. It’s also organized so that if you have some experience with electronics, you can skip chapters and move on to the parts that interest you.
The chapters in this book are divided into parts that also help you find the information that you’re looking for quickly and easily.
Part I: Getting Started in Electronics
Start with Part I if you’re brand-spanking new to electronics. Because this book is designed to get you on the road to electronics as quickly as possible, this part has only two chapters, an overall introduction to electronics concepts and safety information. Please read Chapter 2, “Keeping Humans and Gadgets Safe,” even if you decide to skip the introduction to electronics you find in Chapter 1.

Part II: Aisle 5, Component Shack: Stocking Up
If you’re just starting out in electronics, you probably need a couple of tools. Read about the most important ones in Chapter 3, “Outfitting Your Electronics Bench.”
You can’t make a project out of thin air. You need resistors, diodes, capacitors, and other building blocks of today’s electronics. Chapters 4 and 5 explain what each of the most important electronics components does and how often you use each in building a circuit.
Part III: Putting It on Paper
If you’ve ever seen an electronics diagram, you probably thought it looked like Egyptian hieroglyphics. In Chapter 6, we explain all about how to read these diagrams (they’re called schematics), and you can discover how to follow a schematic to determine the basic functionality of a circuit in Chapter 7.
