how can i get a 8 Hrs dealy ckt for my motor contorl.
it means for 8 Hrs it should be on . after 8 hrs it should turn off automatically.
is it possible with 555 timer or any other suggession
 

what do you mean by "8 hrs dealy"
 

You are expectation will work go with 555 timer concept
 

What is your expected timing accuracy?

In general, you can use 555. But for such a quite long delay, you should use 555 as a oscillator of about Hz, and then use the counter for generating the delay time.
 

I dont use 555 for such a long delay.

Try some other oscillator and followed by divider to get the result.
