In this two-part series, Klaatu introduces you to the Arduino. First, learn about the breadboard and how to make electricity course through it in order to power your very own simple circuit.

To follow along with what Klaatu is talking about, refer to these two

And here are diagrams of the simple circuits that Klaatu constructs.
