ich habe da was fertiges, das ich so oder in ähnlicher Form schon öfters gepostet habe.
Hier ein Beispiel mit 3 Objekten - mit unterschiedlichen Blinkmustern.
Das was du suchst ist die RhythmLed
/* Blink a LED in a specific rhythm
Turns on and off light emitting diodes (LED) connected to a digital pin,
without using the delay() function. This means that other code can run at the
same time without being interrupted by the LED code.
