      Introduction

      Are you curious to know what really goes on inside your iPod, cellphone, tablet, or TV? Do you find it amazing that tiny electronic devices can do so many fun and interesting things? Have you ever wondered if you can build an electronic device that actually does something useful? If you answered yes to any of these questions, you’ve come to the right place!

      Electronics is all about controlling electrical current – which you may know better as electricity – flowing in a complete path called a circuit. All electronic devices are made up of circuits, and every circuit contains a power supply, a path, and one or more parts (known as electronic components) to control current flow.

      By using some basic electronic components to build projects that switch LEDs on and off, sound an alarm when light is detected, tune in a radio station, and more, you can begin to understand how your iPod, cellphone, and computer are able to do such incredible things.

About This Book

      Electronics For Kids For Dummies introduces you to the incredible world of electronics in a fun way: by showing you how to build circuits that actually do something. As you build these circuits, you see for yourself how tiny electronic parts – resistors, capacitors, diodes, transistors, and integrated circuits – work together to control lights, sound, and timing.

      The book walks you through 13 projects (plus a shopping "project") you can build and understand with just introductory knowledge. Each project includes a list of the parts you need, step-by-step circuit-building instructions (with colorful illustrations), and an explanation of how the circuit works.

      By completing all the projects in this book, you will discover

      What it takes to make a complete circuit

      How to build circuits on a breadboard

      What series and parallel circuits are

      How to light an LED – without frying it

      Why switching electrical current between paths is so powerful

      How to pair a capacitor and a resistor to create a timer

      How to use a transistor to boost current

      What you can do with three different integrated circuits (ICs)

      How to create sounds at different frequencies

      Ways to control the sequencing of lights

      How to pull a radio signal out of thin air and amplify it

      Although I can’t promise that you’ll be able to build a project as sophisticated as an iPod after reading this book, I can promise that you’ll build some fun and interesting projects – and you’ll be well on your way to expanding your knowledge so you can tackle more complex electronics projects.

      This book is just a start. The rest is up to you.

Foolish Assumptions

      In writing this book, I made the following assumptions about the interests and skill level of you and other readers:

      You don’t know much – if anything – about electronics.

      You’re interested in building projects that do something useful or fun.

      You’d like to learn the basic principles of electronics as you build your projects.

      You have some money to spend on project supplies and tools. With some smart shopping, $50 will get you most of what you need and $70–$100 will cover everything.

      You’re able to place an online order for electronic components and get to a store or two (probably with help from an adult).

      You will carefully follow the safety tips in this book.
