Basic Arduino Tutorials : 01 Blinking LED

In this instructable, I'm going to show you how to make a simple circuit/code with an arduino, which will make an LED connected to it flash from off to on, with 1-second intervals, as shown below. 
This is a very easy, basic idea, however it leads to many more complicated codes and circuits.

Step 1 What you will need

1 x LED
3 x Cables
1 x 330 Ω Resistor
1 x Arduino board (it can be any kind, but for this instructable i used the UNO board).
1 x USB cable
1 x Computer with Arduino software installed (http://www.arduino.cc/en/Main/software if you haven't already got it)
1 x Breadboard

Optional
Breadboard/Circuit-board Holder.

I know there are a lot of Instructables on Arduino, but most of them begin beyond a beginner level. Arduino is very new and unfamiliar to me. I appreciate your very basic approach for a "newbie." I look forward to anything like a step-by-step tutorial for someone not currently involved with Arduino. Right now my questions involve, "What is it?" and "Why would I want to use it?" If I were to use Arduino, I would want it to do some useful and necessary task best done by it. I would not be interested in "cool" for the sake of "cool." Thanks.

That was my original idea, because when I started using Arduino, I couldn't find any tutorials on basic ideas, and I got very unnerved, So i made this tutorial for beginners, and am looking at making more. Thanks for the feedback!
