Adding the Arduino UNO R3 library to Proteus 8 transforms your PC into a low-cost electronics lab. You can debug logic errors, test pin configurations, and even teach microcontroller basics without a single physical board.
Close Proteus completely (use Task Manager to ensure no background processes are running). Then, relaunch the software. This forces Proteus to refresh its library database and recognize the new files.
