Why do the lights in a house turn on when you flip a switch? How does a remote-controlled car move? And what makes lights on TVs and microwaves blink? The technology around you may seem like magic, but most of it wouldn't run without electricity. Electronics for Kids demystifies electricity with a collection of awesome hands-on projects. In Part 1, you'll learn how current, voltage, and circuits work by making a battery out of a lemon, turning a metal bolt into an electromagnet, and transforming a paper cup and some magnets into a spinning motor. In Part 2, you'll make even more cool stuff as you: Solder a blinking LED circuit with resistors, capacitors, and relays; Turn a circuit into a touch sensor using your finger as a resistor; Build an alarm clock triggered by the sunrise; Create a musical instrument that makes sci-fi sounds. Then, in Part 3, you'll learn about digital electronics-things like logic gates and memory circuits-as you make a secret code checker and an electronic coin flipper. Finally, you'll use everything you've learned to make the LED Reaction Game-test your reaction time as you try to catch a blinking light! With its clear explanations and assortment of hands-on projects, Electronics for Kids will have you building your own circuits in no time.

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, diagrams, and new high quality photographs 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!

In diesem Buch lernst du, coole Dinge aus den gleichen Teilen zu bauen, wie du sie in Fernsehgeräten, elektronischem Spielzeug, Radios und vielen anderen technischen Geräten findest. Die Experimente und Projekte sind sowohl unterhaltsam, wie zum Beispiel ein von Zitronen betriebenes Licht, als auch nützlich (aber trotzdem unterhaltsam), wie zum Beispiel ein Einbruchsalarm und ein Musikinstrument.Teil 1 bildet die Grundlage für den Rest des Buches. Es geht um fundamentale Kenntnisse und wie Elektrizität tatsächlich funktioniert. Du lernst, wie Strom, Spannung und Stromkreise funktionieren, und wie man eine Batterie, einen Elektromagneten und sogar einen Motor baut."Schaltungen aufbauen" ist der zweite Teil, in dem du weitere spannende Projekte wie einen Berührungssensor oder ein Musikinstrument baust. Du lernst einige der wichtigsten Elemente in der Elektronik kennen und erfährst, wie du einfache Schaltungen aufbauen und zusammenlöten kannst.Teil 3 führt dich schließlich in die digitale Elektronik ein, auf der fast alle modernen Techniken basieren. Du bastelst ein Münzwurfspiel und einen Geheimcodetester und schließlich ein ganzes Reaktionsspiel.Nach der Lektüre bist du bestens vertraut mit der Welt der Stromkreise und Elektronik und hast in 23 Projekten jede Menge Spaß gehabt.
