    Hello all
    not an automotive thread.

    I've really been looking hard the last couple of days for a solution, spent countless of hours searching everywhere. Normally am used to finding out all kinds of things myself, but now I'm just stuck. Really need to start looking for good study materials on this kind of subject, i'm really liking it.



    I need to delay a 2 second pulse, for 5 seconds.

    How it is right now:

    12v |¯¯¯2s¯¯¯|_______________


    But I would like it to be like this:

    12v ____5s pause_____|¯¯¯2s¯¯|

    I have found this attachment on this forum, it looks to be what I need but I need different timing. Myself am unable to figure out what rating resistor and caps I need, in order to achieve a 5 seconds pause, and a 2 seconds pulse.

    Is there anyone that can help me out?

    Greetings from Netherlands, Amsterdam.
