LEDCube4x4x4 project made using a 8-bit ATtiny45 microprocessor and three 74HC595N shift registers. Atmel Studio was used to create, compile and flash binary.
I've published original source code with Polish spelling because I can't verify if the project is still working after porting to English (in terms of spelling mistakes/typos committed during porting).
