Electronics for Kids, 2nd Edition

Discover the magic of electricity through hands-on projects designed to teach kids the basics, while having fun and building cool gadgets!

Ready to have the incredible world of electronics at your fingertips? 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 you make decisions, like a coin tosser that chooses heads or tails

The second edition of this bestselling kids book is revised and updated to focus on building a strong foundation of electronics, with more accessible language and less complicated theory. Plus, project product lists are less expensive, with more readily available components and tools. Full-color illustrations, diagrams, and new high-quality photographs provide helpful context and keep you engaged throughout.

透過實踐專案來探索電力的魔力，讓孩子們在樂趣中學習基礎知識，同時建造酷炫的小玩意兒！準備好將令人難以置信的電子世界掌握在你的手指尖上了嗎？用一個會在有人打開你的臥室門時發出警報的裝置來驅趕入侵者，創造一個秘密訊息機器來與朋友溝通，並建造一個能發出時髦數位聲音的可玩樂器，同時學習電池、電流、麵包板等的基礎知識！在你的電子之旅中，你將：使用歐姆定律計算電阻、電壓和電流值；焊接零件到電路板上以創建永久性專案；使用晶體管創建對觸摸有反應的「智能」裝置；將1和0解碼成文字和圖像；建造能幫助你做決策的電路，例如一個可以選擇正面或反面的硬幣投擲器。這本暢銷兒童書籍的第二版經過修訂和更新，專注於建立堅實的電子基礎，使用更易理解的語言和較少複雜的理論。此外，專案所需的產品清單更經濟實惠，組件和工具更容易取得。全彩插圖、圖表和新的高質量照片提供有用的背景知識，讓你全程參與其中。
