I'm using a 555 to create a throbbing effect on a LED, like in this project.
Is there a simple way to delay the signal for a second (then third, then forth...) LED to have them fade in and out at different times?
EDIT: I appreciate the workaround suggestions, but I'm really interested in the original question:
Is there a simple way to delay or phase shift the signal?
Even "it's not possible" or "it's very complicated" are good answers.
