blinking led

what should i use to make my led blinking????resistor??

No.

Look it up, either on this site (use Search) or the wider Web. Lots of LED flasher circuits out there.

555 timer and a resistor to limit the current. If that is too complicated, you can buy blinking LEDs

I would just use a simple 555 timer circuit, like this one:

That's probably the easiest way to do it. Only a few components are needed, and it's easy to put together. The rate of flash depends on the values of the components. I would start with a 10uF cap for C1, and 10K, 1K, and 1K for R1, R2, and R3 respectively. Run the whole thing off of a 9v battery.
Good luck!
