    i was given a challenge project. i need to make a scrolling text using 1digit 7 segment display. i have knowledge in common anode and common cathode display and how to use it with 7447 and 7448 decoder. the problem is that i don't know how to do it if i'm going to make a 5 letter word appear using more than one 7 segment display. i need to make a scrolling dLSUd shifting to the left continuously. from the instructions, i also need to attach a reset button that whenever i "push" it in any position of the "dLSUd", the scrolling must be reset.

    the output must be like this:

    d
    dL
    dLS
    dLSU
    dLSUd
    LSUd
    SUd
    Ud
    d

    and if i'm going to push reset button it must go back to the first output no matter what the position of the output is.
    I don't know where to start. I need to use common cathode display. I also need to simulate it on a Multisim software version 11.0.
