How Bits Work (The basics)

How do bits work, really?  I mean, it isn't like the buzzers will just magically beep and the LEDs just magically glow.  So this is what I learned about what makes the littleBits work the way they do.
Everything starts with energy.  No, this isn't some crazy acupuncture lesson, it's just science.
There are multiple forms of energy, such as electric, heat, sound, nuclear (which doesn't really apply to the LittleBits), and more.
The battery stores the electric energy, which is transferred to the blue module.
When you attach a green module, that electric energy is turned into different kinds of energy.  If you attach a buzzer, it will turn into sound energy.  If you attach an LED, it turns into light energy, and et cetera.
Now on to pink mods.  Say you have a switch.  When it's switched to "off," the circuit is interrupted because the wire inside isn't connected.  When it's switched to "on," it connects and the green mod does whatever it's going to do.
