This is a code for a 3x3x3 LED cube. This cube is run off of 12 pins. To wire this cube, connect all of the anodes on a given level and connect all of the cathodes down vertically in one column. int anode [] ={5, 6, 7, 9, 10, 11, 12, 13, 8}; // sets an aray for lights to be usedint anode2 [] ={8, 13, 12, 11, 10, 9, 7, 6, 5}; // opposeite aray
int catone [] ={2, 2, 2, 2, 2, 2, 2, 2, 2}; // negative for bottom level
int cattwo [] ={3, 3, 3, 3, 3, 3, 3, 3, 3}; // negative for middle level
int catthree [] ={4, 4, 4, 4, 4, 4, 4, 4, 4}; // negative for top level
int x; //sets variables
int d;
int c;
