    Greetings dhan,

    Like AAC, most forums prefer you to create your own thread rather than append your question to an active and possibly related thread. The benefits to this approach are two fold. Firstly, your question is more likely to get the specific attention needed to answer it and secondly it avoids an interruption in the flow of any on-going discussion that is taking place in the existing thread.

    I see you have recently joined our forum. I hope you enjoy interacting with our members and that you obtain the information you are seeking.

    I recommend that you visit our ebook covering Basic Electronics theory at if you have not already done so.

    Have fun,

    Daniel, can you post a schematic? (And can you use proper punctuation and capitalization? It took me several minutes to decode your message into English.)

    Only with a schematic may we deduce why your circuit is triggering falsely after timer-reset.
