Introduction: The Arduino LED Cube!!
Are you bored? Let's try making an LED cube. A work of art, that lights up.

Step 1: What in the World Is and LED?
LED is an acronym for Light Emitting Diode, where electricity can only go one way and when it passes through the "LED" it lights up!
Step 2: Materials You Will Need.
Let's see what you need to make this...
• 27 LEDs - radioshack sells 20 for 3 bucks. You can go to digikey, or be smart and get two packs of assorted LEDs at radioshack.
• Arduino Programming Board - Go to the maker shed or arduino.cc
• Some like 2ft of wire(choose your favorite)
• A breadboard for connecting all the pieces.
• A soldering iron!
and your set to go!

and your set to go!
Step 3: Assemble the Cube!
So as you can see in that first picture. The cube is 3x3x3. Which means a 3x3 led in one layer, and three layers of 3x3 LEDs.
You need to make a jig for this. I used foam core and basically drill some holes in a 3x3 matrix shape about 1/2 an inch between each hole.
now, when you have all of your LEDs in the holes and the pins are sticking up to the sky you need to bend the cathodes.
Easy enough to understand. The longer one is the positive and bear with me, this one is called the anode.
now you want to bend the cathode (the shorter one) the way the arrows go on this picture. Then when that cathode is bent it should be touching the other LEDs cathode. This is your soldering place.(melt the solder here).
Great all done! Now you have a 3x3 led square. Repeat this step two more times so you have three.
Lay those three LED squares on the table in front of you. now, i used some wire we discussed earlier to connect them all. On the squares there should be 9 anodes sticking up. You want to connect the anode of the first LED square to the corresponding anode one the second layer.
So, when your finished you should have 9 columns of anodes.
Then you need to solder you some wires going from the negative connections of all three layers. You should end up with three separate wires coming from the negatives(the cathodes).

Step 4: So Your's Should Look Like This
Exactly, Now you need to connect all of these anode pins to your breadboard and make sure that you have access to the rows they are on. Leave the cathode wires there.
Step 5: Programming Time!
I found this awesome program here:

I'll save you a trip and post the code right here. Load this up to arduino via the arduino environment you can download at arduino.cc (a website).

I'll save you a trip and post the code right here. Load this up to arduino via the arduino environment you can download at arduino.cc (a website).

Step 6: Connecting All of the Pins
K get some wire and you set to go.
Connect the first one all the way on the top left to analog 2 on the arduino board.

number 4 anode to analog 1
number 5 anode to digital 4
number 6 anode to digital 6
number 7 anode to analog o
number 8 anode to digital 5
and number 9 anode to digital 7
then connect the top to bottom wires in this order analog 3, 4, 5.
Connect the first one all the way on the top left to analog 2 on the arduino board.
