Activating LED on signal input=null

Sighline:
If it was possible creating a blinking stage between 0 and >0 it would be even better !Like two blinks on LOW and three blinks before going HIGH

There isn't anything between 0 and >0. Any positive number is >0. And no program can see into the future to know that it is going to be greater than 0 in a while, just long enough to do a few blinks.
