You’ve probably heard of light-emitting diodes, a type of energy-efficient light. ... Switches in circuit diagrams are often represented by a break with a bent line, like this: In this activity, you ...

Fluorescent lights are being phased out in favor of long-lasting, energy-efficient LEDs, so the best way to replace a fluorescent light is to not replace it at all. Instead, swap out fluorescent ...

Diodes are electronic components that can be used to regulate the voltage in circuits and to make logic gates. Light-emitting diodes (LEDs) give off light and are often used for indicator lights ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully ...
