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 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, Electronics for Kids will have you building your own circuits in no time.
