Proteus 8.13+ includes Visual Designer for Arduino. The top RC522 libraries are now compatible with the Flowchart mode. This allows you to drag-and-drop RFID blocks without writing a single line of C++.
Paste RC522.IDX and RC522.LIB into the LIBRARY folder. If you are using a portable version of Proteus, paste them into the LIBRARY folder inside the installation directory. rc522 proteus library top
