Good Morning
Thanks for your responses. Yes ,Mr. Deb it is exactly what I need. sorry if I was not so clear at first. I hope that it can be carried out less compicated with only a 555. Curtis, you have mentioned that it can be done wite a 555, which is more popular and may be more simple then with the MAX. could you please be more specific about it (with a short explanation, please, because I want to understand it, not just build it).
Thanks.
btw. as I mentioned before - a second or two, more or less - doesn't matter.
