Ensure the Arduino TX pin connects to the Virtual Terminal RXD pin (crossed connection). Check that your code matches the virtual terminal baud rate (9600).
Double-click the Arduino Uno in Proteus and load the .hex file from your Arduino build folder. Click "Play". Troubleshooting the Simulation
Use the Arduino IDE with the MFRC522 library. Ensure the SS_PIN and RST_PIN match the connections in Proteus (usually pin 10 and 9). rc522 proteus library
Without a library, you have two options: build the circuit in real life (costly and time-consuming for iterations) or populate your Proteus schematic with generic placeholders (which do nothing). The RC522 library changes this by providing:
Navigate to your Proteus installation directory. The default paths are: Ensure the Arduino TX pin connects to the
| Your Goal | Recommended Approach | |---|---| | Test RFID reader logic in code | Use EM-18 model (reliable workaround) | | Validate full RC522 hardware design | Build physical prototype (simulation not possible) | | Learn RC522 programming | Use real hardware + Serial Monitor debugging | | Complete a project for submission | Simulate with EM-18; note substitution in documentation |

Search for "RC522 Proteus Library" online. Numerous GitHub repositories and community forums offer the files. Ensure you are downloading a package containing the MFRC522.LIB and MFRC522.IDX files. Step 2: Install the Library Files Copy the downloaded .LIB and .IDX files.
