A common mistake that halts simulation is a mismatch between the microcontroller's clock frequency setting in Proteus and the value assumed in the firmware source code.
Simulating all of this accurately would require complex models that aren't commercially viable to develop as free libraries. rc522 proteus library
To make the RC522 work in a simulation, you will also need the for your firmware. The standard pin configuration for an Arduino Uno is as follows: Arduino Pin SDA (SS) SPI Chip Select SCK MOSI SPI Data Out MISO SPI Data In RST VCC Power (Do not use 5V) GND 4. Adding Text to Your Schematic A common mistake that halts simulation is a

Every electronics enthusiast remembers the magic of tapping an RC522 RFID card on a reader. The red light flashes, the serial monitor screams out a UID like A3 12 7F 4B , and suddenly... a servo moves, or an LCD welcomes you by name.
Ensure your simulation includes common ground anchors. Microcontrollers require clear pull-up or established signal levels to parse incoming simulated SPI arrays correctly. If you want to expand your simulation setup, let me know:
