How to simulate Arduino in Proteus (legitimately): Error: "No HEX file specified for Arduino"

Absolutely. While new EDA tools like KiCad 8 and Falstad’s Circuit Simulator exist, they lack the robust MCU co-simulation found here.

One of the most powerful tools for an embedded systems engineer is the ability to test code without touching physical hardware. Proteus Design Suite (version 8.9 SP2 is a stable favorite) allows you to design schematics and simulate circuits, while the Arduino IDE (1.8) is the industry standard for writing the code.

However, getting these two to talk to each other can be tricky. If you’ve just installed Proteus and tried to drop an Arduino UNO onto the workspace, you might have noticed it doesn't do anything when you load a sketch.

Here is how to bridge the gap and run your first simulation successfully.
