Happy simulating!
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. rfid rc522 library for proteus download
void loop() if ( ! mfrc522.PICC_IsNewCardPresent()) return; if ( ! mfrc522.PICC_ReadCardSerial()) return;
mfrc522.PICC_HaltA(); delay(1000);
Serial.print("UID: "); for (byte i = 0; i < mfrc522.uid.size; i++) Serial.print(mfrc522.uid.uidByte[i], HEX); Serial.print(" ");
✅ Saves money, speeds up debugging, great for teaching. ❌ Cons: Not 100% accurate for advanced features. Serial
void setup() Serial.begin(9600); SPI.begin(); mfrc522.PCD_Init(); Serial.println("Place a tag near the reader...");
Without the library, you can’t test your Arduino or PIC code logic for reading UID tags. You either have to buy physical hardware or abandon the simulation. mfrc522
