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.
