Description
Book SynopsisWhy 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 soundsThen, 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
