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.
Øyvind Nydal Dahl built his first circuit at 14 and has been passionate about electronics ever since. He has a master’s degree in electronics from the University of Oslo, helps companies develop new products, and travels the world while teaching electronics workshops. He also writes beginner-friendly tutorials.
“Don’t be fooled by the title. This collection of 23 hands-on projects for tinkering with (and learning about) simple electronics is substantive enough to engross even gadget-loving adults.”
—The Wall Street Journal
“I learned and retained more in this single book than I can recall learning from my own science teacher. Most importantly, I loved reading it. I often took it to work with me in my bag.”
—The Huffington Post
“There’s no better way to learn than by doing. So go ahead, turn the page and begin your adventure into all that electronics has to offer!”
—Joe Grand, from the Foreword
