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!

Frank! Someone’s stealing the sandwich!

Frank!?.. Frank?

Aww man…
