Experimenting with batteries, bulbs, buzzers, switches and other electrical components is a great way to learn about circuits and start to think about how to incorporate sounds into your Build a ...

Output devices such as motors, solenoids, bulbs, buzzers, relays, LEDs, and 7-segment displays are used in many electronic circuits. Circuit diagrams illustrate how these devices are connected.

The functions of basic electronic components are revealed through a series of experiments as students figure out how to create circuits that light up LEDS, sound buzzers, use resistors to dim lights, ...
