Question relating to delaying 555 timer pulse

[krappleby]

Hi everyone,

im a beginner in electronics, and im currently working on a project and need a little bit of advice. I have a 555 timer circuit which creates a pulse, i need to break that pulse into two seperate signals, however the 2 set of pulses need to be delayed by 5 pulses...

for example

1 2 3 4 5 6 7 8 9 etc
0 0 0 0 1 2 3 4 5 etc

any ideas on the best way to do that.. I was debating using some sort of logic and relay, but im sure there is an easier method.

once the fifth pulse on the first signal is recieved, i need the second set of signals to activate from then on as well.. so both lines will be creating a pulse from the 555 timer, but the second line cannot start until the first five pulses have been processed..

thank you for your time

Here's one possible way to do it.  (See attached.)

Hi I understand most of this but what is the CP1 Low (pin)

i can see how this would register 1 pulse at Q4, but what is the CP1 pin..? is that some sort of lock?
and what would that IC be, as looking at decade counters i cant see one with a second clock pulse pin.. cheers

The IC is the 4017 decade counter.  You could also use a 4022.

That is the Clock Inhibit pin.  Pin 13.  (I'm not sure why it has that name in the simulator.)

If the pin is held high then the counter won't advance.  So, once the counter gets the 5th pulse it will stop counting and the Q4 pin will remain high.
