Is there an arduino emulator with code execution?

Question

Arduino

Found a great visual builder for Arduino: fritzing.org
It has an IDE for the code, but no execution.
There is an online 123d.circuits.io with a visual designer and code execution, but there are few components. In particular, there is no ultrasonic rangefinder.
Is there anything that unites?

Answer 1

Scratch for arduino

Answer 2

Yes, there is: 123d.circuits.io
I burned virtual arduin there so many times :)
