Hi guys:
Is there a way to hook up a 555 timer to function as an "on delay" type
timer? In other words, when you hold the trigger line it waits for a
specific time, then activates the output. I have schematics that show how
to wire it in "one shot" mode, but that doesn't do me any good.
It would also be nice if I could trigger it with a logic "high" rather than
a "low". Is this possible? Maybe another chip besides a 555?
Thanks for any replies.
