Proteus 8.9 SP2 is a significant update in the Proteus Design Suite , offering several features that streamline the workflow for hobbyists and professionals:

Double-click the placed Arduino component to open its properties dialog. Locate the Program File property field.

Download the Arduino library files for Proteus ( .IDX and .LIB files). Copy these files.

– SP2 runs smoothly on Windows 10/11 (and even on moderate Linux/Wine setups). I’ve run complex projects with an Arduino, an I2C EEPROM, and a keypad without noticeable lag.
