hi....
i am trying to make a delay circuit with 555 timer that will turn on a 12V DC Load.
i designed a monostable ckt. i attached its schematic here. here when the push button is pressed the output remains high for 30 sec. i think this is a basic monostable design.
what i want is when the power will be turned on the output will remain off for 30 sec. then after 30 sec... my load will be turned on.
so, my questions are...
1. is my monostable ckt is right?
2. what i need to do to design my requirements?
3. do i need any relay or transistor?
4. do i need the push button in my required circuit?
thnx
