Its spirit lives on in Tinkercad Circuits (which still simulates Arduinos and breadboards for free) and in Wokwi (a modern, fast Arduino/ESP32 simulator). But for those who used it, 123D Circuits remains a fond memory—the tool that made "I built a digital clock in my browser" possible long before it was common.

Autodesk 123D Circuits served as a critical bridge between the hobbyist and professional worlds. By democratizing access to SPICE simulation and PCB design, it empowered a generation of makers to move from "playing with wires" to manufacturing professional hardware. While the platform itself has been sunsetted in favor of more robust tools like Fusion 360 and Tinkercad, its impact on lowering the barrier to entry for hardware engineering remains undeniable. autodesk 123d circuits

They also saw the rise of competitors like (which Autodesk also acquired in 2013) — a simpler, more purely "kid-friendly" 3D design and circuits tool. Its spirit lives on in Tinkercad Circuits (which

As the maker market matured, Autodesk realized they had two overlapping products: By democratizing access to SPICE simulation and PCB
