MFRC522 mfrc522(SS_PIN, RST_PIN);
Introduction The RC522 is arguably the most popular RFID/NFC module for hobbyists and engineers working with Arduino, PIC, and AVR microcontrollers. Its low cost (often under $5) and ability to read and write 13.56MHz Mifare Classic cards make it a staple in access control, inventory systems, and smart locking mechanisms. rc522 proteus library
void setup() Serial.begin(9600); SPI.begin(); mfrc522.PCD_Init(); Serial.println("Scan a virtual card..."); Serial.println("Scan a virtual card...")
However, before soldering a single wire or risking physical hardware, every smart developer simulates first. This is where Proteus Design Suite (specifically Proteus ISIS) shines. But there is a catch: rc522 proteus library
void loop() // Look for new cards if (!mfrc522.PICC_IsNewCardPresent()) return;
