For breadboarding your next great Arduino-powered robot, maybe not so much. So for educational purposes, it is great. In addition, the selection of components is somewhat limited (including only supporting the Arduino UNO, as far as we could tell). The layout is very visual, so if you are accustomed to reading schematics, you may not appreciate the style. This could be great for teaching Arduino in classrooms or when you want to do some development in a hotel room. You can also build simple circuits that don’t use an Arduino, although the component selection is somewhat limited.

You can even get to the serial monitor, all in your browser with no actual Arduino hardware. You’ll find an integrated code editor and a debugger. There are a variety of components you can add to your design. recently did a video about a new Tinkercad feature: building and simulating virtual Arduino circuits. This popular CAD package runs in your browser and was rescued from oblivion by Autodesk a few years ago.

If you’ve done 3D printing, you’ve probably at least heard of Tinkercad.
