3D hardware simulation tool in your browser (LEDs only for now)

A short pointer to a browser-based 3D hardware simulator for prototyping simple electronics (LED projects for now), handy while Arduino's future looks uncertain.

People are a little afraid Arduino would be a dead end project since it was purchased by Qualcomm it seems (your code belongs to them, no reverse engineering allowed, data collection, etc.). So basically they would probably be bitten by ESP if it is not already the case.

But if you’d like to simulate some Arduino projects, or just simple LEDs blinking before Xmass, I just discovered a new project thanks to @nono2357 post on X which allows you to simulate an Arduino project without the hardware… I mean physically, here it is: https://www.withdiode.com/

I just played with already made projects, but seems cool, you can design everything on a protoboard like this:

Access the code editor, exactly like running the Arduino binary:

For the moment, the list of parts is a bit limited, but I guess that would be fulfilled in the future:
