Baca data RFID card dengan RDM6300, arduino, lalu tulis data RFID ke SDcard (Dinamis File Name pada SDcard)

Alat dan bahan :

Arduino uno

Sdcard module (catalex product) + SD card nya

Kabel jumper male to female

Power supply bisa via usb , bisa via adaptor 7-15 volt

RDM6300 + antena

RFID tag 125khz

LCD 2x16

Variabel resistor 20 kilo ohm


library yang digunakan :

1 SD card
2 Software serial
3 LCD


Konfigurasi PIN LCD

/*

 The circuit:
 * LCD RS pin to digital pin 10
 * LCD Enable pin to digital pin 9
 * LCD D4 pin to digital pin 8
 * LCD D5 pin to digital pin 7
 * LCD D6 pin to digital pin 6
 * LCD D7 pin to digital pin 5
 * LCD R/W pin to ground
 * 20K var resistor:
 * ends to +5V and ground
 * wiper to LCD VO pin (pin 3)
  */

Konfigurasi PIN RDM 6300

VCC - 5 volt
GND- GND
TX to digital pin 2 arduino
antena to antenna


konfigurasi pin SD card module


 ** MOSI - pin 11 on Arduino Uno
 ** MISO - pin 12 on Arduino Uno
 ** CLK - pin 13 on Arduino Uno
 ** CS -  Pin 4 Arduino Uno
 ** VCC - 5 volt
 ** GND - GND

}


NB :

catatan --> sketch   char filename[temp.length()-7];//--> 'index dalam pemrograman itu diawali dengan 0 ,1,2,3,4,5,6,7

menunjukkan bahwa RFID di copy sebanyak 8 digit awal, total ada 12 digit, namun penamaan file pada SDcard hanya di izinkan maksimal 8 digit karakter,

Selamat berekperiment

mas mau tanya ,,,saya lg buat proyek tugas akhir sebuah lock dor dg rfid,,,nah nah dosen saya minta reader nya itu dikasih 2 jadi cara kerjanya controller hanya akan bekerja apabila tag nya didekatkan ke reader 1 lalu reader 2 dg kombinasi Read1-Read2-Read1 lagi ,,,,yang seperti itu apakah bisa ya mas ?? mohon penceranhanya dan referensinya mas
