The standout feature: . You could write Arduino code in a web-based IDE, attach it to a virtual Uno, and watch LEDs blink, servos turn, or serial output appear – all without hardware. This wasn’t just a SPICE simulator; it was a microcontroller emulator. For learning, this was gold. You could debug logic errors before soldering a single joint.
In 2017, Autodesk streamlined its "123D" apps. The electronics simulation portion was moved to , where it lives today as Tinkercad Circuits . 123d circuits
