LED Problem

I just got the arduino today and i only have an LED in the arduino and it blinks I haven't even put any code in yet, can someone please help me

where did you put it, the default action of the arduino is to blink a led on digital output 13

The default program flashes the LED on Pin 13. That's normal.

[u]Absolutely do not connect ONLY a LED.[/u] You need a current limiting resistor too.
