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 logic circuit simulator and truth table interface Computer Structure and Language final project Main project No.1: Logical circuit simulator on an Arduino/ESP32 chip using JavaFX as a ...

It allows you to simulate analog circuits, LCDs, stepper and servo motors and can include programmable PIC or AVR (including Arduino) processors in your simulation.

This repository contains the comprehensive modelling, simulation, and physical implementation of an LCR circuit. The project spans from theoretical derivations using ordinary differential equations ...
