How to control 64 LEDs without using 64 individual wires? Multiplexing!
Running a wire to the anode of each led would obviously be impractical, and
would look really bad.
One way to get around this, is to split the cube into 4 layers of 16x16 LEDs.
All the LEDs aligned in a vertical column share a common anode (+).
All the LEDs on a horizontal layer share a common cathode (-).
Now if i want to light up the LED in the upper left corner in the back (0,0,3), I just
supply GND (-) to the upper layer, and VCC (+) to the column in the left corner.
If i only want to light up one led at a time, or only light up more than one layer at
the same time.. this works fine.
However, if I also want to light up the bottom right corner in the front (3,3,0), I
run into problems. When I supply GND to the lower layer and VCC to the front
left column, I also light up the upper right led in the front (3,3,3), and the lower
left LED in the back (0,0,0). This ghosting effect is impossible to workaround
without adding 64 individual wires.
The way to work around it is to only light up one layer at a time, but do it so fast
that the eye doesn't recognize that only one layer is lit at any time. This relies on
a phenomenon called Persistence of vision (http://en.wikipedia.org
/wiki/Persistence_of_vision).
Each layer is a 4x4 (16) image.
If we flash 4 16 led images one at a time, really fast, we get a 4x4x4 3d image!
Step 3: Making the cube, template

Soldering grids of 4x4 LEDs freehand would look terrible!
To get 4 perfect 4x4 grids of LEDs, we use a template to hold the them in place.
I wanted to make the cube as easy as possible to make, so I chose to use the
LEDs own legs as much as possible. The distance between the lines in the grid
was decided by the length of the LED legs. I found that 25mm (about an inch)
was the optimal distance between each led (between the center of each led that
is!) to enable soldering without adding or cutting wire.
Find a piece of wood large enough to make a 4x4 grid of 2,5cm on.
Draw up a 4x4 grid of lines.
Make dents in all the intersects with a center punch.
Find a drill bit that makes holes small enough so that the led will stay firmly
in place, and big enough so that the led can easily be pulled out (without
bending the wires..).
Drill the 16 holes.
Your ledcube template is done.

Step 4: Making the cube, solder the layers
We make the cube in 4 layers of 4x4 leds, then solder them together.
Create a layer:
Put in the LEDs along the back and along one side, and solder them
together
Insert another row of LEDs and solder them together. Do one row at a time
to leave place for the soldering iron!
Repeat the above step 2 more times.
add cross bracing in the front where the led rows are not connected.
Repeat 4 times.
Step 5: Making the cube, connecting the layers

Now that we have those 4 layers, all we have to do is to solder them together.
Put one layer back in the template. This will be the top layer, so choose the
prettiest one :)
Put another layer on top, and align one of the corners exactly 25mm (or
whatever distance you used in your grid) above the first layer. This is the
distance between the cathode wires.
Hold the corner in place with a helping hand and solder the corner anode of the
first layer to the corner anode of the second layer. Do this for all the corners.
Check if the layers are perfectly aligned in all dimensions. If not bend a little to
adjust. Or re-solder of it's the height distance that's off. When they are perfectly
aligned, solder the remaining 12 anodes together.
Repeat 3 times.
Step 6: Choosing resistor values

There are two things to keep in mind when choosing a resistor value for your
leds.
1) The LEDs
2) The AVR
The AVR has a maximum combined current rating of 200 mA.
This gives us 12mA to work with per LED.
You also don't want to exceed the maximum current your leds are rated to.
I used 220 ohm resistors on my cube. This gave me about 12mA per led.
Step 7: The controller

The circuits controlling the led cube is described in the attached schematic
image.
The RS-232 interface is optional. and can be omitted. That is IC2 and all the
components connected to it. Future firmwares will enable PC communication..
Start by laying out all the components on you circuit board in a layout that
enable all the components to connect with a minimal amount of wires. If
everything fits, solder the circuit.
I won't give any more instructions on this, as the circuit probably will look very
different from cube to cube, depending on the size of the circuit board etc..
Information on how to wire the cube to the controller circuit is in the next step.

Step 8: Wire up the cube
Pictures explain this better than words. Please see the pictures.
Step 9: Compile and program
You now have a led cube. To make use of it, it needs some software.
I have made a driver for rendering a 3d data space on the cube, and functions
to display some cool visual effects on the cube.
You can use my code, write your own or build on my code and make more
effects.
If you make your own effects, please send me the code. I'm eager to see what
you guys make!
To compile the program. Just open a command promt,
enter the directory with the source code

type "make" on the command line.
If you want to use an ATMega32 instead of the ATMega16, just change the mcu
setting in the Makefile and recompile (type make). If you use the m32 and don't
do this step, the cube won't boot properly (the red and green lights will keep
blinking forever).
You should now have a file named main.hex in the source directory.
The next step will show you how to get that code into your cube.

Step 10: Program the microcontroller
If you are experiencing problems with speed and/or some LEDs not
lighting up. Please read this step carefully.

To program the microcontroller, I use avrdude and the USBTinyISP
programmer.
http://savannah.nongnu.org/projects/avrdude/ (http://savannah.nongnu.org
/projects/avrdude/)
http://www.ladyada.net/make/usbtinyisp/ (http://www.ladyada.net
/make/usbtinyisp/)
http://www.adafruit.com/index.php?main_page=index&cPath=16
(http://www.adafruit.com/index.php?main_page=index&cPath=16)
My examples will be on an Ubuntu Linux system. The procedure should be
pretty much identical on Windows, but I can't help you with that. If you use
another programmer, read thet manual for that programmer and avrdude.
First off, Let's just see if we can make contact with the AVR.
Connect the programmer to your cube and your computer.
The command is "avrdude -c usbtiny -p m16", wherer -c specifies the
programmer, and -p the AVR model. You can see the output in the images
below.
Now, upload the firmware: "avrdude -c usbtiny -p m16 -U flash:w:main.hex".
By now, the cube should reboot and start doing stuff. It will be running at 1mhz
(very slowly) using it's internal oscillator. And some of the leds won't work,
because some GPIO ports are used for JTAG by default.
To enable the external oscillator and disable JTAG, we need to program the
fuse bytes:
run "avrdude -c usbtiny -p m16 -U lfuse:w:0xef:m"
and "avrdude -c usbtiny -p m16 -U hfuse:w:0xc9:m".
Be carefull when doing this step! If you get it wrong, you can permanently
destroy your microcontroller! If you are using another microcontroller than the
ATMega16, be sure to read the datasheet carefully before changing the fuse
bytes!
After writing the correct fuse bytes, the cube should reboot and start
operating at regular speed with all leds operational.
Enjoy your new cube :D

waka2007 (/member/waka2007/)
I want to make this for my first real project. I was wondering how important are the
transistors and the capacitors. I have seen cubes that run with just LEDs and
resistors so why the extra stuff?
mpick92 (/member/mpick92/) waka2007
The short answer is because he built
his development board from scratch.
If you look at an Arduino, all those
components are placed on the board
when it is manufactured (and then
you have the input/output pins to
use).

Hi guys
I built the circuit without the rs232-interface and programmed the (above
attached) hex-file to the chip with a separate programmer. The status-leds are
working, but none of the led's are lighting up. I measured the outputs (at cathode
out from transistors and anode) and was surprised when my multimeter gave me
a negative voltage.
Has anyone experienced the same problem ever?
Steve25 (/member/Steve25/) wildatheart123
I build it to without the rs232
interface and did not have that
experience. Did you connect
you're transistors right? My
transistor had an TO-92 package
(CEO). I nearly connected them
wrong.

Hi Steve, You were right. I
connected the transistors
wrong. Now some Leds are
lighting up but they only go
on for about 10 secs and off
again. Did you program the
chip in circuit as in this
instructable or on a separate
programmer?
Steve25 (/member/Steve25/) wildatheart123
Yes i followed all steps in this
guide. When i uploaded the
program, 4 rows didn't light up.
But after setting the fusebits it
worked perfect.
If you also followed all the steps
there might be an problem in
you're wiring.
wildatheart123 (/member/wildatheart123/) Steve25
Hi Steve
It's running now! I indeed set the
fuses wrong. thanks for your help!
all the best
Steve25 (/member/Steve25/) wildatheart123
Great to hear! I'm happy that you
got it working.
Steve25 (/member/Steve25/) wildatheart123
I build it to without the rs232
interface and did not have that
experience. Did you connect
you're transistors right? My
transistor had an TO-92 package
(CEO). I nearly connected them
wrong.

Can i use 16Mhz Crystal instead of 14.7456?
I just cant wait if ill buy the exact 16Mhz that i need. xD
manoulis (/member/manoulis/)
Hey dude, nice work there, I'm trying really hard to make one myself, I have
entered the atmel site but I see two different types of Atmel AVR Atmega16
microcontroller in PDIP.
Here is the link of the site too: http://www.atmel.com/devices/atmega16.aspx
Can you please tell me which one should I order ??? Thank you in advance
Steve25 (/member/Steve25/) manoulis
I bought the atmega16-16PU. But you can use the atmega16-8PU aswell
so the choice is yours

Thank all for answers. Now I have othe trouble, not all of leds is working and
some always lithing very brightly.
Steve25 (/member/Steve25/) sadomukas
Hi sadomukas. I can't tell what's
causing this problem i only can give
you suggestions. First check out
you're connections again. If that's all
good then check you're resistor
value's. If the value's are good as
well then check you're leds. There is
a possibility that you're leds are
damaged. To check this out, take
out you're volt meter and put it on
bleep ore diode. You're Leds should
light up when you touch them. If
they do not then they are broken
and should be replaced.
If this is all good then the last thing i
can think of is that you broke you're
chip again.
Hope this will help you out good
luck again!

Hi everyone. Please help for me. I have done this cube, but when i try to
programme it LM 7805 makes verry hot ant computer cant connect to atmega16

An another
suggestion if you
use you're usbasp
with windows you
should install a
driver for it. This
can be the reason
why you can't
connect you're
computer to you're
atmega16! This
driver can be found
at
http://www.fischl.de
/usbasp/. This
driver is called
usbasp-
windriver.2011-05-28.zip.
Good luck and
hopefully you can
get it working!
Steve25 (/member/Steve25/) sadomukas
Hi sadomukas. The firsting you
should check are you're
connections? Is everything
connected right to you're
ATMEGA16?
If you are programming don't
connect you're 12v power supply!
You're programmer already giving
5v! If you do you can cause alot of
damage to you're chip and circuit!
Did you change the programmer
in you're program to usbasp
instead of usbtiny?
And at last did you use the right
resistors?
Hope this suggestions will help
you out! Goodluck
Steve25 (/member/Steve25/)
Hey chr i got a couple of questions. I want to build this cube but why did you put
in jumper 3? Its not standing on you're components list so can i leave it out? And
why do you have connected a connector to the 323max ic? Well hope to get a
respond so i can start building!

I made a scrolling font that works on this 4x4x4 cube. By making the font 4 wide
by 5 tall, and scrolling vertically, it becomes recognizable. It required a new file,
font.c, and some changes/additions to draw.c, and you have to add an #include
line in main.c. If you are interested, it can be found on github here:

Awesome job. I just finished building mine. I have one issue, hoping someone can
make a recommendation on. The column that connects to pin 29 of the chip does
not work. There is continuity from the pin to the column, so it's not a break in the
circuit. I am not sure how to troubleshoot. Any ideas? Other than that column, it
works beautifully.
mrdrako (/member/mrdrako/) mrdrako
Disregard. For some reason the pin was not making contact in the socket.
Removed and reseated the chip and it works!
Now I can start playing around!
tboultwood1 (/member/tboultwood1/)
For the metal bracing, what sort of wire did you use? Not sure on what to buy for
that :S Great guide!

Would it be possible to power a 5x5 cube using the same AVR, but using different
code? How would that be possible? regards
Cubytus (/member/Cubytus/)
Hi,
I want to start constructing this 4x4x4 monochrome LED cube since I have a ton of
big yellow LEDs I can't find any use for. I just noticed that I still have a plenty of
LEDs, so would I be able to drive a 5x5 cube with slighty changing the code of the
Atmel AVR, without any other change? Or does it need a bigger power supply?
xsandman.32 (/member/xsandman.32/)
Hey, just wanted to say thanks for this incredible instructable! I finished my cube
a couple weeks ago (nearly) flawlessly by following these directions. Next up: an
8x8x8, and learning to etch the pcb in an attempt to make the circuit footprint
smaller.

Hi there , I just built this version of a rgb 4x4x4 cube
http://www.freetronics.com/products/cube4-4x4x4-rgb-led-cube
Since it uses Ardunio the code is quite different ... Is there a way to Translate your
animations , so that they would work with the cube I built?
viveksridhar (/member/viveksridhar/)
Can you let me know if I'm calculating the resistor values for the transistors
correctly?
Since there are 16 LEDs connected to each transistor, the current limiting resistor
for those LEDs would be 40 ohms.
If I'm using a 2N2222 transistor (Hfe = 100), with the base voltage at 5v, wouldn't
the base resistor be 312 ohms?
Sorry if this is a stupid question, but I'm just trying to understand how you get the
resistor values and how they relate to the transistor and everything.
