FRID-RC522 Sensor adalah contacless reader/writer yang mendukung semua varian dari MIFARE Mini, baik protokol identifikasi MIFARE 1K maupun MIFARE 4K, MIFRARE Ultralight, MIFARE DESFire EV1 dan MIFARE Plus RF. Berikut ini adalah gambar sensor yang dimaksud.
Adapun Pin Dengan Pin sebagai berikut:
Adapun Pin pada Wemos D1 mini pro adalah sebagai berikut:
Sehingga Interfacing antara RFID-RC522 dengan Wemos D1 mini pro adalah:
pin SDA ke D2
pin SCK ke D5
pin MOSI ke D7
pin MISO ke D6
pin IRQ diabaikan
pin GND ke GND
pin RST ke D4
pin VCC ke 3V3
Setelah melakukan interfacing, maka kini saatnya untuk mempersiapkan lingkungan pengembangan dengan mendownload Arduino RFID Library for MFRC522 yang dapat didownload pada link, setelah download, maka pada sketch pilih menu :
