Story

Much of the project is about simple programming of the 3x3x3 LED cube, but it’s importantit was also to be fun. The essence of programming is that + 5V is connected to a column and -5V is connected to a row.

The positive legs of the LEDs should be connected per column, the negative 
one on each floor.
