I use that in a lot of Circuit VR posts so you can click on a circuit and see it live. However, the simulator does not save the source code in the virtual Arduino. You have to do that yourself.

This shield could be a good alternative to hobby RC controllers for robots that need a customizable open-source motor controller. The PCB design and source code are available on GitHub.

A Gadget Master has built their own VR motion simulator, powered by an Arduino and using recycled parts from an electric mobility scooter.
