Winner of Editor's Choice
Top Pick for Kids
What is the bus part of the breadboard?
Top and bottom rows of holes. They are connected horizontally
Understanding the Genius Light
when a large amount of light hits the photo resistor its resistance is low, when there is a little amount of light its resictance is low.
What is the resistor's role in a circuit?
To slow down the flow of electricity so the LED does not burn out.
Segmented LED Explained
that if you had a lot of led lights that they would share positive energy but they have there own negative energy:)
EEME Dad's comments: Each LED segment shares the same positive prong but has their own individual negative prong.
What is the terminal strip of the breadboard?
The terminal strip is the 2 middle portions of the breadboard.
Turn On Switch - How It Works
What happens is the resistor, working like a dam is resisting some of the current flows to the switch pannel. It's also making a connection to the switch pannel, so what happens when you take it out, it turns off. Then the switch is acting like a door, when you turn the on switch up, you open the door. when you turn the on switch off, you close the door. It's like closing the flow of electric current.
