reseting my arduino board?

i had run the blink code on my arduino but i cannot undo it ( bring it back to having no code run on it) i tried pressing the reset button but the blink code still continued, i even tried to cut the power,

Your Arduino board will run its current program every time you power it on, until you overwrite the program with a new one. It never has "no code" running on it, but you could open up a blank sketch and program your Arduino with it, which would make it appear to do nothing.
