    Does it have to be programmable or static text? Do you need fancy stuff like scrolling etc.? Is it a homework?

    I got no pdf, maybe you could try googling a bit, I am pretty sure there will be some projects existing. Do you have any idea about the size of the display you want, as in rows and columns?

    Nevertheless, why does it specifically need to contain 555 and 4017? I personally would just use a microcontroller.

    i said 555 and 4017 because a microcontroller is a bit complicated
    so googling i already did that and i even got a project for merry xmas
    which was made by a microcontroller.
