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
This wonderful teaching resource has the reader build nine graded
