Tutorial Penggunan Modul MF522-AN, 13.56 MHz RFID Reader

Pada postingan sebelumnya saya sudah mengenalkan sedikit tentang modul MF522-AN, jika kalian belum membacanya silahkan klik disini. Kali ini saya akan menjelaskan bagaimana cara menggunakan modul ini. Modul ini akan saya integrasikan dengan Arduiono Board, lebih spesifiknya saya menggunakan board Arduino Uno.

Pada dasarnya, pada kesempatan kali ini saya akan memberikan tutorial bagaimana menggunakan modul MF522-AN untuk membaca dan menuliskan data pada kartu RFID, namun pada tutorial kali ini saya hanya akan memberikan tutorial untuk membaca RFID saja, sedangkan untuk cara menulis data saya akan jelaskan di postingan berikutnya.

Sedikit informasi mengenai data yang diolah oleh modul ini, data yang disimpan berupa data denngan tipe ASCII yang dirubah kedalam bentuk desimal. Dengan kata lain, jika kita menginputkan kode ASCII maka data yang akan tersimpan di dalam kartu berupa data biner.

Sebelum masuk ke tutorial, saya kana menjelaskan sedikit tentang kartu RFID, kartu RFID ini banyak sekali variant nya, mulai dari yang kapasitasnya kecil hingga yang kapasitasnya besar. Data yang ditulis disimpan kedalam beberapa sektor pada kartu RFID. Kebanyakan kartu hanya memiliki 8 sektor penyimpanan, dan salah satu sektornya sudah di khususkan digunakan untuk identitas kartu.

Data ASCII yang akan diinput kedalam kartu pertama-tama kita masukan dulu kedalam sebuah array agar memudahkan dalam proses penyimpanan data. Array yang berisi data tersebut kemudian ditransfer melalui modul MF522-An ke kartu RFID. Masing-masing data pada array bisa kita simpan di sektor kartu sesuai dengan keinginan kita. 

Berikut adalah langkah menggunakan modul RF522-AN.

1. Persiapkan alat dan komponen yang diperlukan.

• Breadboard
• Arduino Board
• Modul MF522-AN
• Kartu RFID
• Kabel jumper secukupnya

2. Setelah semua alat dan komponen dipersiapkan, hubungkan modul dengan Arduino Board dengan konfigurasi sebagai berikut.

Reset > Pin 5
SDA > Pin 10
MOSI > Pin 11
MISO > Pin 12
SCK > Pin 13
Ground > Ground
3.3v > 3.3v


3. Buka Arduino IDE kemudian masukan upload sketch beriku:

4 Setelah selesai, buka serial monitor pada Arduino IDE, coba dekatkan kartu RFID dengan modul dan perhatikan apakah kartu terdeteksi atau tidak pada serial monitor. Untuk lebih jelasnya kalian bisa lihat video berikut ini.

Nah itu dia cara pengguanaan modul MF522-AN sebagai RFID reader. Sekian dulu ya tutorial dari saya, semoga bisa bermanfaat buat kalian, kalau ada kesalahan pada skema rangkaian atau pada source code kalian bisa hubungi saya disini.
