This instructable is made for those who know how to solder (well) and how to program the Arduino. Also I will be providing detours to skip sum steps so if you see (Detour available skip to __ Step) you can follow if you are to lazy to do that.

Mandatory
-- 64 LED (color optional) **
-- Arduino Demulionove
-- Wire
Optional
--32 male pin strip
--PCB prototype board
--Fine Grit (400 +) sand paper
Your choice
-- 64 resistors or 16
you can get 64 resistors which will help by keeping all the lights at the same light out put regardless of how many are on but it will be considerably more work.
Tools:
--Computer
--Soldering Iron
--Solder
--thin nose pliers
**Color is optional but use this website to find the right resistor for your leds http://led.linear1.org/led.wiz (I got Green so I used 100 ohm resistors)

There are sixteen "B0000" groups per line. One would think that each group corresponds to a vertical column, and the 0s and 1s indicate the plane, and whether the light is on or off.
But that's not how it seems to work for me, and I can't figure it out.
The java applet on makecode.html always prints the same line, sixteen B1111s, no matter what boxes I have checked. The only thing that changes is the duration number, which does correspond to what I enter in the box. But everything else is always B1111s.
Can you please help me understand the pattern strings?
I made the code in Dreamweaver and I will try to make it Cross-platform compatible but I can't promise anything: I am just an amateur!
Making the code for great patterns is kind of difficult, so I made a little Javascript program to make designing them more easily. It basically works as follows. You see four squares: the first square is the front layer, the second, the one behind that, the third the one behind that and the last is the back layer. You can set the LEDS on or off and when you have made a pattern, and have set a time in a text box, you can write it to a text area. Then make another one, and another one and.. When you are finished, you can copy the contents of the text area and paste it in the Arduino Code. Then go for it!
Try it here: http://home.kpn.nl/ajvdmeij/makecode.html. If you want the source code, you can copy it or tell me and i will mail it to you.
Have fun!

I have a question...I am using these LEDs...
http://www.ebay.pl/itm/110783289032?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_1456wt_1139
I have resistors of all the values from 1 ohm to 1 mega ohm....in 10's ....
So which resistors will I need to use for those LEDs? The cube is connected to an arduino nano...
plz help :)
Oh, and if you have the electronic circuit, would be great.
Thank you.
Great project, congratulations!
It will be very helpful for me.
(sorry for my bad english)
By the way,
This ible is awesome! It helped me a lot! Thx for the ible!
my english is not so good but this link helped me alot with my led cube ..

Thanks
how cmoe you connect 4 different wires to it, please answer.
To set a pin to GND:
pinMode(pin,OUTPUT);
digitalWrite(pin,LOW);
i thought the same thing at first but then someone helped me so.
Thanks
Mike
as far as i know, those pins can supply V out but not gnd, in confused.
Do you understand me??? can you explain me how these work??
The i/o pins are very universal in use i begin to love my arduino more and more every day!!
Mike
also, I think that the resistor is not to protect the arduino, but the LEDs, since they are normally 3v and the Arduino is 5.
good explanations and also yu do not need to put resistors on each led just the coloms.
ill be making an 8x8x8 soon (hopefully)
and the resistor is like a 2 way protection:
led --> arduino protects arduino
arduino --> led protects the led from burning out
hope this mekes it easier :-)
thanks
hopefully will have it soon
My leds will just blink as random and not in order when I use the code. 'Cause I wired them up just randomly. Which ports should I be using?
There is something I do wrong, but I don't know what. Please help!
Still I don't understand 2 things:
1) EndTime = millis() + ((unsigned long) DisplayTime) * TIMECONST;
why this unsigned long?
2) #define TIMECONST 20 // multiplies DisplayTime to get ms - why not =100?
..
why not?
