Question

Answer 1

OMG! It's been a long long time. And one second is a long long time. You're going to have to check the specifications for the 555 and make the pulse as long as you can that's a power-of-two fraction of a second, like 1/64 or 1/128 or 1/1024 and you'll have to divide it down, with something.
