New to Fritzing with problems

Hi, I’m starting to use Fritzing; the platform I normally use is Tinkercad and I see that it’s quite different. Well, I have a problem: I put together a simple project and it turns out that when I start the simulation nothing happens; the Arduino board goes gray. I suppose it’s a matter of powering the board (in Tinkercad that’s assumed by default).

How do I make it work?

Thanks

Simulation in Fritzing is for general electronics, not micro controllers. Not all electronics Fritzing components can be simulated either. Only those that have spice data included.
