wieso "perfekt" oder nicht?
Der angegebene Link von Greensiver http://tronicstuff.blogspot.de/2013/...ube-4x4x4.html ist doch genial!

PARTS:
64 LEDS.
ATmega328P.
General purpose PCB.
Ribbon cables.
Arduino board to program the ATmega328P/USB to UART converter.
4 x BC547 transistors.
4 x 1K resistor
4 x 100 Ohm resistor.
Jumper wires.

das klingt doch, als ob es top funktioniert, was willst du mehr?...AS THE ARDUINO IS SOURCE THE LED ANODES WHICH GO TO DIGITAL PINS 0-9 and 14-19 AND THE CATHODES ARE SINKED THROUGH A 100Ohm RESISTOR THROUGH A BC547,SO THAT LOGIC LEVEL REMAINS THE SAME IN THE PROGRAM..i.e to ground the leds you have to put HIGH on the pins 10,11,12,13 respectively according to the grid.
