BEHIND ALL LIGHTS ARE CIRCUITS THAT HELP ELECTRONS FLOW FROM A POWER SOURCE TO THE LIGHT BULB & BACK OUT.
LET'S BUILD A CIRCUIT WITH little Bits!
Batteries provide the power (the combination of voltage & current)!
Every circuit starts with power! It drives a current through a circuit.
This LED will end the circuit by turning electricity into light!
HOW ABOUT TURNING THE LIGHT ON & OFF WITH YOUR FINGER?
When you press the button, it lets the signal pass through
WHAT IF YOU WANTED TO CONTROL HOW BRIGHT YOUR LIGHT IS?
As you slide the dimmer up, more signal goes to the light making it brighter.
NOW THAT YOU KNOW HOW A CIRCUIT WORKS YOU CAN INVENT YOUR OWN LIGHTS!
