Hi guys, I am not getting delay of 1 sec.blinking rate of 7 segment is too fast in comparison of delay calculated(=1sec). Any help will be appreciated.. thanks
per above my guess is that yur delay is 1/2 what you expect
Yes, that is how I interpret the details.
I don't understand how/why the OP changed my original talk of halving the delay and replied with the:
yes it is nearly double.
Must be one of those cases where I read it as I wanted to see it in my following response.
My favorite was the OPs statement:
but i think u read the datasheet incorrectly ...
As if he'd been reading and understanding it beforehand (faceslap)
