Electronics for Kids

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. <p/><i>Electronics for Kids</i> 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: <br>-Solder a blinking LED circuit with resistors capacitors and relays<br>-Turn a circuit into a touch sensor using your finger as a resistor<br>-Build an alarm clock triggered by the sunrise<br>-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 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 <i>Electronics for Kids</i> will have you building your own circuits in no time.
