Electronics for Kids, 2nd Edition

Learn to (safely) control electricity with the click of a button, the tip of a 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 safely teach the basics while having fun and building cool gadgets. 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, breadboards, and more! Throughout your electronics journey, you’ll: - Explore how resistance, voltage, and current work- Solder components to a circuit board to create permanent projects- Use transistors to create “smart” devices that react to touch- Turn 1s and 0s into words and images- Build circuits that help you decide things, like a coin flipper that randomly picks heads or tails This second edition is revised and updated to focus on building a strong foundation of electronics, with more accessible language, less convoluted theory, and a focus on inexpensive, readily available components and tools. Full-color illustrations and diagrams provide helpful context and keep readers engaged. Ready to have the incredible world of electronics at your fingertips? After reading Electronics for Kids, you will be!
