How to make a 7x7x7 LED cube with Arduino.

I always wanted to make my own LED cube, and now I share with you my project.

Step 1
The first thing to do is create the LED matrix.

In this case I have created seven 7x7 LED matrixes.

I have divided anodes and catodes and I have soldered them in rows and columns, so at the end I have 7 anodes and 7 chatodes for each led matrix.”
