555 timer self reset

Hello,

Did AAC not help you:
555 timer self reset.

Bertus

Most of the circuits there included using flip flop IC. I am planning to give 555 a try before changing IC. There was a circuit there which I tried but didn't work.

Although I will spend more time on this circuit as well.

My circuit is configured for 3.3v logic level

So why do you have a 7V supply?

Sorry. I should have explained clearly. At first, it was 7V in settings. After that I also tried with default 3.3V to see what happens.

All logic should use the same level as the 555. The OR as well as the NOT.

All logics are same. Still no result. It goes into monostable but doesn't reset. You can access my circuit as well. go to https://www.multisim.com/discover/ and search "sahilsiwatch_555"

This one worked for me. Thanks for all your efforts
