    How do you know the project is great if it is not working? ;)
    The main problem is an Arduino vision of the micro controller. In reality the pins are not the same! And you cannot replace one arduino pin with another one in any case. In schematics the encoder is connected to pins d2, d6 and d3 (button). The d2 and d3 pins can receive interrupts (0 and 1) and these interrupts are really used in the sketch. Also, the atmega328 micro controller has hardware spi port on pins d13 (sck), d11 (mosi), d12 (miso - not used because the display do not send any data) and d10 (ce). If you connect the display to these pins, you can use the hadware spi to send data to the display, or you can simulate this protocol by software if you connect the display to another pins.
    The const declarations in the skech can confuse you, but they are not expected to be changed.

    Hello!

    This display module has own micro controller which translates the high-level command from serial (UART) interface to the low-level chip led display activation events. Surely, this display could work as a clock by its own. :) You can investigate this display and learn some useful technics. Unfortunately, this clock project deals with low-level display and if some one would use your serial display with this project, he or she would rewrite almost the whole sketch code.

    Hello!
    Yes, everything is possible.
    What do you mean by "serial" display?
