The 4x4x4 LED Cube (Arduino)





Introduction: The 4x4x4 LED Cube (Arduino)

In this instructable I will show you how to make a 4x4x4 LED cube that will be controlled by an Arduino Demulionove. now yes you might say" that Arduino has only 14 I/O pins well also the 6 analog pins can be used as pins 15,16,17,18,19,20. that way giving us enough pins (16 columns + 4layers = 20 I/O pins)

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.

Step 1: Get the Materials

To start of you will need these materials:

-- 64 LED (color optional) **
-- Arduino Demulionove
-- Wire

--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.

--Soldering Iron
--thin nose pliers

**Color is optional but use this website to find the right resistor for your leds (I got Green so I used 100 ohm resistors)

Step 2: Assemble the Board(the LED Cube Base)

(Detour available skip to next step)

In this step you will need the board and the wiring. First you will want to map out were all the wires will go and then feed the wires through the board. Don't mind the LED and resistor note on the picture for now.

NOTE: I recommend you use Different color wire just because you won't get confused which wire is which.


Step 3: Defuse the LED

DETOUR if you don't want to do this then go to next step

So to defuse the LED I took normal 400 grit sand paper and sanded all the LEDs which made them look pretty good.

Step 4: Construct the Cube

Now there is the Easy way to do this and that is to connect all the (--) in one layer and then the columns (+) to the resistor and then board. (Look at picture diagram below) what happens is when you turn it on (all of them) the lights are dimmer then when one is on.

My solution to this was to solder a 100 ohm resistor to each LED. (Follow picture instruction on how to do it.) Everything is done in the same way only now you solder all the resistors to the column which is a piece of Ethernet wire. (See picture)


Good job on making it too this step now all you need to do is upload this code and you are done.

the code did not fit the line so here it is

Step 6: ADD On

so to program the cube all you need to do is change the 

B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, B1111, 80,

each B1111 corresponds to a line of LEDs in your cube 0 being off and 1 being on. The last number is the time it will display that part in milliseconds.

so get programing and enjoy.

hello i am a beginner to programming and is interested in this project.Can you sent the description to my id

Hello, from what I understand from the code, you multiplex the cube by turning on one layer at a time by connecting the cathodes for that layer to GND, and then turning on the columns you want to be lit by putting 5V on them with a series resistor. In this way you only need 16 resistors, since at any given time, there is always just one LED active per resistor and output.


Are you powering the cube using only the arduino? and will an arduino uno be enough to make it?

is there away of using the random number command to make paterns

I want to know how to code for the patterns. how can i design my own codes?

I made a program that can produce patterns real easy. Would you like me to share it?

Yes, that will be helpful. Thank you!

Thanks for your help.
