Wokwi seems to be the most popular Arduino-based one.
I'm not a huge fan of simulation for cases like this. The arduino forums are full of "it worked in simulation, but not on my breadboard..." complaints.
Also, simulation won't teach you not to connect a 10ohm resistor across a 12V supply and then touch it. Or that capacitors may explode when connected in reverse polarity, or just how to be careful in general. There's a lot of stuff that should become second nature, but you'll only learn by connecting physical circuits.

There may be better ones out there, I just found this quite accessible to get started with.
