thnx for the reply, however i have a problem with some code.
i looked at this tutorial: http://www.instructables.com/id/3X3-LED-Cube-Programming-tips-Arduino-based/
this looks really easy to make patterns, if it works.
when i want to upload the code:

#include <avr/pgmspace.h> // allows use of PROGMEM to store patterns in flash
#define CUBESIZE 3
#define PLANESIZE CUBESIZE*CUBESIZE
#define PLANETIME 3333 // time each plane is displayed in us -> 100 Hz refresh
#define TIMECONST 5 // multiplies DisplayTime to get ms - why not =100?
// LED Pattern Table in PROGMEM - last column is display time in 100ms units
// TODO this could be a lot more compact but not with binary pattern representation
prog_uchar PROGMEM PatternTable[] = {
B101, B010, B101, B000, B000, B000, B000, B000, B000, 50 ,

** Defining pins in array makes it easier to rearrange how cube is wired
** Adjust numbers here until LEDs flash in order - L to R, T to B
** Note that analog inputs 0-5 are also digital outputs 14-19!
** Pin DigitalOut0 (serial RX) and AnalogIn5 are left open for future apps

then i get this errors:
sketch_jan07a:34: error: expected ',' or ';' before 'int'
sketch_jan07a.ino: In function 'void setup()':
sketch_jan07a:45: error: 'LEDPin' was not declared in this scope
sketch_jan07a.ino: In function 'void loop()':

what can be the problem?
