I just thought there was some easy command.
There isn't any such thing in the Arduino. Somebody did create a library that would let you define an action to be carried out after a delay or at regular intervals, but it's so easy to do yourself once you understand how 'blink without delay' works that I don't think it's necessary to use a library; you're only looking at a couple of lines of code for each separate thing you want to control. In any case I suggest that this is so simple to do that you should do it yourself first, even if you subsequently decide to use somebody else's solution later.
