If you’ve ever tried to simulate an RFID-based access control system or a contactless payment prototype in Proteus, you’ve likely hit the same wall: The standard Proteus library does not include the MFRC522 (RC522) module.
✅ Saves money, speeds up debugging, great for teaching. ❌ Cons: Not 100% accurate for advanced features.
Serial.println();
Serial.print("UID: "); for (byte i = 0; i < mfrc522.uid.size; i++) Serial.print(mfrc522.uid.uidByte[i], HEX); Serial.print(" ");
MFRC522 mfrc522(SS_PIN, RST_PIN);
