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.

Arduino boards are perhaps the world’s best known amateur microcontroller – cracker-sized circuit boards that cost about $30 and, say, govern the intake of information or the actions of a motor. They ...
