user13760: Is it possible to do something like this: send a HIGH signal to an output pin, after a 0.33s delay arduino sends HIGH signal to another pin, and after another 0.33s delay, arduino sends signal to third pin. There has to be 90 seconds long high signal for each pin, but with 0.33s delay between each other. 
Sooo something like this; start of the high signal on left, stop on right side:
pin1: 0 ...... 90.00
pin2: 0.33 ... 90.33
pin3: 0.66 ... 90.66

Is there a way to solve this?

user4143: Yes. Read the BlinkWithoutDelay example and triplicate it.
