Circuit symbols

You’ve got some seriously cool stuff here, Frank.

If we’re putting this Sandwich Intruder Alarm together, we’re going to need a diagram!

Sweet.

Each of these symbols are different electrical parts.

We just need to arrange them in to a circuit!

First we need power, man – this symbol here is a cell, or battery.

That one’s a motor – we don’t need that one.

But that’s a light bulb – we can use that.

Let’s finish off with the buzzer, to make some noise!

But we need the power to flooowww – let’s join it all up with wires.

Don’t forget the switch – we’ll set it up so if someone treads on it, the switch will close, setting off our alarm!

Let’s check it out!

Niiiice…

Frank! Someone’s stealing the sandwich!

Frank!?… Frank?

Aww man…
