    Hello Friends ;

    Friends, I have a repeating timer ... I have attached in my attachment.. please have a look !


    And i want :

    I want that this repeating timer to run for only four time because at running 24hr's a day the
    time period will not be precise...

    SO I want to run this repeating timer at least four times , and after four timer it
    should turn off and stay turn off for 1 hr... and after 1hr it should starts to run again..
    up till four time...
    And this repeats...

    As I am new in electronics field ...... but I hope we will need counter and Oscillators..
    For 1hr timer we can use Cd4060 and we can also use as counter to sense 4th pulse...

    eg : 1 , 2 , 3 , 4 (from repeating timer) and after running four time the repeating timer
    will become off and cd4060 timer will start to run for 1hr...

    It just a guess... as I am new so ....

    Friends I need your help's and suggestions to complete this !

    Thanks :)

    There are ways (with other design concepts) to make it a lot more precise.

    Interested?
