Simulating a circuit

Hi there. I am totally new to this platform but really enjoying it so far. I’ve just built a simple LED timer circuit but I cant figure out how to simulate it. Is this possible? The circuit works from a push button.

Thanks for any help.

Fritzing is not a simulator. This is also made clear at our FAQ at .

A feature request to add this functionality exists, and first basics are done using SPICE. However, a simulation would be limited to small subset of parts. LED and a Button would work, but not much more, which makes the feature quite expensive and not very useful.
