However, having a simulated Arduino with a debugger could come in handy even if you don’t care about the circuit simulations. If you really want to do circuit simulation, it is hard to go wrong ...

There’s a simulation of a Galton board, which demonstrates the central limit theorem nicely. Don’t forget that Tinkercad can do other tricks, too, like circuits, Arduino code, and Lego.

The Complete Circuit Design and Simulation Super Bundle is on sale right now for just $59.99, allowing you to learn more about this field and see if it's the right one for you.
