A Beginner's Guide to Circuits is the perfect first step for anyone ready to jump into the world of electronics and circuit design.

First, you’ll learn to read circuit diagrams and use a breadboard, which allows you to connect electrical components without using a hot soldering iron! Next, you’ll build nine simple projects using just a handful of readily available components, like resistors, transistors, capacitors, and other parts. As you build, you’ll learn what each component does, how it works, and how to combine components to achieve new and interesting effects.

By the end of the book, you’ll be able to build your own electronic creations. With easy-to-follow directions, anyone can become an inventor with the help of A Beginner’s Guide to Circuits!

Build These 9 Simple Circuits!

  • Steady-Hand Game: Test your nerves using a wire and a buzzer to create an Operation-style game!
  • Touch-Enabled Light: Turn on a light with your finger!
  • Cookie Jar Alarm: Catch cookie thieves red-handed with this contraption.
