Klappentext

Learn to control electricity with the click of a button, the tip of your finger, and even the light from the sun!

Why do lights blink? How does a speaker make noise? In Electronics for Kids, you’ll discover the magic of electricity through hands-on projects designed to teach you the basics while having fun and building cool gadgets. 

This second edition is revised and updated to focus on building a strong foundation of electronics, with more accessible language and less convoluted theory. Each project’s product list requires cheaper, more readily-available components and tools. Full-color illustrations, diagrams, and new high-quality photographs provide helpful context and keep you engaged throughout.

Ward off intruders with an alarm that buzzes when someone opens your bedroom door, create a secret message machine to communicate with friends, and build your own playable musical instrument with funky digital sounds—all while learning the ins and outs of batteries, electric currents, breadboards, and more!

Throughout your electronics journey, you’ll:

Calculate resistance, voltage, and current values with Ohm’s law

Solder components to a circuit board to create permanent projects

Use transistors to create “smart” devices that react to touch

Decode 1s and 0s into words and images

Build circuits that help decide things for you, like a coin tosser that randomly chooses heads or tails

Ready to have the incredible world of electronics at your fingertips? After reading Electronics for Kids, you will be!
