If you only need to , simulate using a generic SPI EEPROM (e.g., 25AA1024 ) or a virtual terminal + custom code.

Place a Virtual Terminal, connecting TX to RX and RX to TX of the Arduino, or connect the serial output of the RFID module to the terminal to see tag IDs. Below I cover: #include #include #define SS_PIN 10

The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. It supports SPI, I²C, and UART protocols and is widely used with microcontrollers like Arduino, STM32, and Raspberry Pi. 3.3V Operating Frequency: 13.56 MHz Read Range: Up to 30mm (physically) 2.

Serial.println(); Serial.print("Message : "); content.toUpperCase(); Place a Virtual Terminal, connecting TX to RX

When you develop a system with an RC522 module, it typically requires: an external antenna coil, a few passive matching components, a 3.3V regulated power supply, and a host microcontroller to drive it via SPI. The goal of using a Proteus library is to faithfully replicate all these aspects inside a virtual environment.
