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 2: Order the parts for the cube!

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 5: Order the parts for the controller and solder it!

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.
