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!

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. (http://cdn.instructables.com/FY1/HMAK/FE7ITUD3/FY1HMAKFE7ITUD3.LARGE.jpg)
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.

We make the cube in 4 layers of 4x4 leds, then solder them together. (http://cdn.instructables.com/F3I/B9T2/FE7ITUHG/F3IB9T2FE7ITUHG.LARGE.jpg) 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. (http://cdn.instructables.com/FMT/HDF3/FE7ITUIE/FMTHDF3FE7ITUIE.LARGE.jpg)
Repeat 4 times.

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. (http://cdn.instructables.com/F2S/5TH2/FE7ITUKJ/F2S5TH2FE7ITUKJ.LARGE.jpg)
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.

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.

The circuits controlling the led cube is described in the attached schematic image. (http://cdn.instructables.com/FK1/LGWS/FE7ITUU1/FK1LGWSFE7ITUU1.LARGE.jpg)
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. (http://cdn.instructables.com/F3P/62AA/FE7ITUVT/F3P62AAFE7ITUVT.LARGE.jpg)
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.

You now have a led cube. To make use of it, it needs some software. (http://cdn.instructables.com/FA8/4EF1/FEAHE8WE/FA84EF1FEAHE8WE.LARGE.jpg) 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
19.04.2014 18:13

The procedure should be pretty much identical on Windows, but I can't help you with that. If you use (http://cdn.instructables.com/FII/OZYZ/FNI43W6X/FIIOZYZFNI43W6X.LARGE.jpg) 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

The short answer is because he built (/member his development board from scratch. /mpick92/) 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 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?

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?

Yes i followed all steps in this (/member guide. When i uploaded the /Steve25/) 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.

Great to hear! I'm happy that you got it working.

I build it to without the rs232 (/member interface and did not have that /Steve25/) experience. Did you connect you're transistors right? My transistor had an TO-92 package (CEO). I nearly connected them wrong.

Hey dude, nice work there, I'm trying really hard to make one myself, I have the atmel site but I see two different types of Atmel AVR Atmega16 microcontroller in PDIP.

I bought the atmega16-16PU. But you can use the atmega16-8PU aswell so the choice is yours

Hi sadomukas. I can't tell what's (/member causing this problem i only can give /Steve25/) 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 sadomukas. The firsting you (/member should check are you're /Steve25/) 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

Hey chr i got a couple of questions. I want to build this cube but why did you put 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 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 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.

Disregard. For some reason the pin was not making contact in the socket. and reseated the chip and it works!

Would it be possible to power a 5x5 cube using the same AVR, but using different How would that be possible? regards

Hi, (/member /Cubytus/)
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?

Hey, just wanted to say thanks for this incredible instructable! I finished my cube 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.

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?

Can you let me know if I'm calculating the resistor values for the transistors (/member correctly? /viveksridhar/)
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.
