    What I'm looking for is to take a signal from a 555 timer, and "count" it for 6 counts, and vary the output on each of the 6 counts.

    After those 6 times I want it to reset and go back to the beginning.

    Forgive me for not being more specific, I am just looking to see if there is anything like this available.

    This is my conception of what it would look like.


    count signal ---> count 1 output
    ---> count 2 output
    ---> count 3 output
    ---> count 4 output
    etc etc.


    Is there any IC or anything which can do anything like this?

    Thanks.

    Well, not quite sure what you mean by "vary the output on each of the 6 counts". :confused:

    A while back, I drew up a schematic for a fellow who wanted a timer circuit that could change pulsewidths on every count. Didn't use a 555 timer, but a 4093 Schmitt-trigger NAND gate as an astable multivibrator, with a 4017 Johnson counter to select different pulsewidths for the next time duration.

    See the attached.

    Looking at it I believe a 555 would work.
