There is a way to blinnk a led without the delay() function?

i whant to blink a led every 1 min, but in the normal way i use something like this

digitalWrite(13, LOW);
delay(1000);
digitalWrite(13, HIGH);
delay(1000);

but i whant to blink and be able to push a button or something else but when the program is in the delay(); part the program are in "pause", so there is a way to blink a led without stop the program for the delay duration?

Like using PWM that is the same but alot faster xD

Of course there is. There is even an example called, not unsurprisingly, Blink Without Delay.

Or instead of having to deal with all the timer tick polling, look at some of the timer libraries.
Some use interrupts, some depend on getting updates in loop()
