    Hey guys,

    i have an assignment, in which i have to design a 555 timer to light up for the same amount of days as the day of my birthday, and off for the month of my birthday.

    e.g 3rd november
    on for 3 seconds, off for 11 seconds.

    i have designed and tested my 555 timer circuit works perfectly.

    the 2nd part of the assignment is to investigate other circuits which could perform the same task.
    so far i have got it working on a binary counter circuit using JK flip flops.

    do you know any other circuits that could do this?

    many thanks.

    A 4047 timer IC or a microcontroller can do it.
