Tutorial Pemrograman dan Pembacaan Tag Input RFID-RC522 Menggunakan Arduino Uno R3

Kali ini saya akan berbagi Tutorial Pemrograman dan Pembacaan Tag Input RFID-RC522 Menggunakan Arduino Uno R3. Jika tag terdeteksi dan dikenali oleh Arduino, maka Arduino akan menampilkan output sesuai kondisi yang didapat pada Serial Monitor Arduino IDE. Anda bisa download dahulu Library Arduino nya di link berikut ini : DOWNLOAD LIBRARY.

1. Arduino Uno R3 >>> BELI DISINI
2. RFID-RC522 >>> BELI DISINI
3. Kabel Jumper >>> BELI DISINI

Berikut ini adalah gambar rangkaiannya :

Koneksi antar PIN seperti berikut ini :

Berikut ini adalah Code Programnya :
