Rc522 Proteus Library ((exclusive)) May 2026

Proteus is known for its unique ability to simulate microcontroller code (specifically Arduino HEX files) alongside electronic components. However, out of the box, Proteus does not include a native RC522 model. Enter the third-party RC522 Proteus Library: a custom simulation model that bridges the gap, allowing you to simulate your entire RFID project before soldering a single component.

Use the Terminal Mode in Proteus to add a POWER terminal of 3.3V. Do not tie VCC to 5V. Even in simulation, some models enforce voltage limits and will “fail” (output undefined logic levels) if overvolted. Writing the Arduino Sketch You will use the standard MFRC522 library in your actual Arduino IDE. Here is a minimal sketch to simulate reading a tag UID: rc522 proteus library
