Binary clock panel and firmware - full project

Hi, this is my simple project with binary clock. There is used Arduino mega 2560 and RTC DS1302.
Program work with Arduino UNO (Atmega328P) too - tested! But only need chagne the pin conection, for UNO :
RTC is unchanged - myRTC(7, 6, 5); // CLK, DATA, RST
Outputs column pins for LEDs - "LED 1"= pin 8; "LED 2"= pin 9; "LED 4"= pin 10; "LED 8"= pin 11; "LED 16"= pin 12; "LED 32"= pin 13;
Outputs for rows is unchanged - 2 green seconds, 3 yellow minutes and 4 red hours.
