You are welcome!
sometimes i see code with like delay(1) delay(2) all over the place. whats the reason for that?
I assume for the same reason I proposed a delay: to give something time to change states. But, without a context, I have no way to answer definitively.
i mean, in this case, ok it takes time to switch, so u want to wait a little bit.
It takes very very little time to switch; eight or fewer machine instructions. The delay I suggested is three and a half orders of magnitude shorter than delay(1)
is that the only reason to use delay at all?
That's the only reason I would ever use delay
do you know if there r important differences between those 4051?
I have no idea. Someone else will have to help with that question.
