Close all active instances of Proteus and relaunch the software to re-index the component library. Circuit Schematic: Wiring RC522 with Arduino Uno in Proteus
When building your simulation, use the following pin mapping to connect the RC522 to an (a common pairing for RFID projects): Arduino Pin SDA (SS) SPI Chip Select SCK Serial Clock MOSI Master Out Slave In MISO Master In Slave Out IRQ Interrupt (Usually not used) GND RST 3.3V Power Supply (Crucial for physical units)
// If the UID is valid, turn on an LED if (isValidUID(mfrc522.uid)) digitalWrite(LED_PIN, HIGH); delay(2000); digitalWrite(LED_PIN, LOW); rc522 proteus library updated
What you are planning to use (Arduino, PIC, STM32)? Which version of Proteus you have installed?
If you absolutely require a Proteus model: Close all active instances of Proteus and relaunch
: Some updated versions include a "Card Search" or "Tag" component that mimics bringing an RFID card close to the reader during simulation. Installation Guide
: In Proteus, double-click the Arduino component and select the file in the "Program File" section. If you absolutely require a Proteus model: :
Open Proteus Schematic Capture, press to open the Pick Devices window, and search for the following components: Arduino Uno (Microcontroller) MFRC522 / RC522 (The newly installed RFID module) COMPIM or Virtual Terminal (To display serial data) LED-GREEN & LED-RED (For status indication) RES (330-ohm resistors for the LEDs) 2. Wiring the Circuit
Double-click the RC522 component in Proteus. In the updated library properties, you will see a field to specify the card UID data file or text string. Input your desired simulation hex value (e.g., 21 A3 B5 C7 ).
