Hello
its really great video and innovative. Can you share me schematic for it?

[@doit.20]

Thank you for your comment. unfortunately I don't have its schematic. I thinks you can make connections as below;
RTC(10, 11, 12);// clk, dat, rst
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);
LCD_BACKLIGHT_PIN 9
btnChange = A1;
btnOK = A2;
btnMode = A3;
