Picture of Build your own 4x4x4 RGB LED Cube

LED Cubes are awesome. The first one I created was a 8x8x8 blue led cube. It still works like a charm. But being able to display every colour in the spectrum is much more spectacular. Let's start with a small and simple 4x4x4 RGB LED Cube.

Step 1: Watch part 1 of the video series!

As you might have noticed, part 1 concentrates on the cube itself and the case. No electronics yet. The video should already give you plenty of details. But I will give you a short list of parts that you will need to build the cube itself.

Step 3: You finished the cube and case!

Congrats on your finished cube and case. It should now look a little bit like mine in the picture. Go ahead and test all connections with a power supply. If everything works fine you can go ahead and build the electronics in the next steps.

Step 4: Watch part 2 of the video series!

The video gives you plenty of info on how to build the controller for the cube. In the next step I will give you the schematic for the circuit and the part list.

Step 6: Upload the arduino code and test the cube!

Download the code for the LED Cube. This is already my updated version of the code which I showed in part 3 of the video series. Be sure to watch this part as well to get an idea how the code works.

Step 7: Watch part 3 of the video series!

This time it is all about optimisation. You may get a better understanding of the code if you watch the video carefully.

Step 8: Success!

You did it. You just finished your own 4x4x4 RGB LED Cube. Feel free to develope the code in more creative ways than I did. And feel free to share those new creations.

Does it matter that much which kind of arduino I use. I have an arduino uno

hkerr tyxman1 month ago

shouldn't as long as it is connected to the right pins. so yeh it should work

hkerr made it!1 month ago

I just need to finish the case but havent had time in the last few weeks.

I am also interested in Integrating the MSGEQ7

I have attached MSGEQ7 pins attached to
pin 3 to Atmega pin 23/A0
Pin 4 to Atmega pin 14/d8
Pin 7 to Atmega Pin 12/d6

But have no idea how to code it. please let us know if you work with this

Is it possible to make it react to mp3 files and make a vu meter that would be awsome

GreatScottLab (author)  Olek4102 months ago

It is definitely possible. Maybe I will give it a try in the future with a MSGEQ7.

i made the circuit but all it does is change from rgb rgb thats all..I used a arduino duemilanove..Please help..Thanks..

GreatScottLab (author)  domdomgin2 months ago

Did you use the v2 of the code? Or the one in my second video?

i see only one code.also i used the arduino duemilanove is that fine..i checked all connections and all seems fine..kindly suggest.also changed the tcl config lib to 3 tlc..

GreatScottLab (author)  domdomgin2 months ago

duemilanove should work just fine. But it does something at least. So your circuit should also work. I suggest playing around with the code a little could at least give you hint what is going wrong.

Thank you for this great inscrutable..Would like to know the value of the cathode current limiting resistors if they are required..

Also if you could give another explanation on your code on how to make some new animations..thank you..

How much of the bridge wire will i need to buy? (length)

GreatScottLab (author)  hkerr2 months ago

I used around 12m

Thanks for the quick reply. I bought 100m instead of just 15m.
