The 123D Team at Autodesk has released some new updates to their latest addition to the 123D family. The main updates include the ability to accurately simulate capacitors and inductors in real time and display signals on a virtual Oscilloscope. There are new of components that can be simulatable in the breadboard editor. They’ve included logic chips, transistors, and a couple Arduino-compatible boards. They’re building the simulation models for each new component, so if you have a request, drop them a suggestion!
