Introduction: Arduino RFID and 5110 Screen/ID Card Reader(Rc522)
Hi there, today we are going to use Rfid(RC522 with 5110 screen. But this sensor is different than others. Because we will use EEPROM.
We want to;
1 - When we show our ID card we see the ''Welcome Ensar Levent'' on the 5110 screen.
2 - When we show our card second time, it doesn't read.
Let's start..
PLEASE FOLLOW ME AND VOTE MY PROJECTS FOR MORE USEFUL PROJECTS. THANK YOU..:)
Step 1: What Is the EEPROM?
EEPROM is the memory of Arduino. So Firstly we will show our card and save them to EEPROM. Then we will upload the other code.
Step 2: Connections;
RC522 to Arduino;
3.3v to 3.3v
RST to D9
GND TO GND
IRQ TO (NONE)
MISO TO D12
MOSI TO D11
SCK TO D13
SDA TO D10
5110 TO ARDUINO;
GND TO GND
LIGHT TO (OPTIONAL)
VCC TO 3.3V
CLK TO D2
DIN TO D3
DC TO D4
CE TO D6
RST TO D5
Step 3: Codes;
How can we use the these codes?
Firstly you must upload the Setup code and Show two ID Card. If you show same card 2 times device won't work.

Dostum projen gayet güzel, bunu wifi veya 3g ile internete bağlayıp, okutulan kartları uzaktan takip etme olsa daha guzel olurdu böylece personel takibi gibi isler icin ticari olarak da kullanılabilir. Diğer projelerinde başarılar..

Teşekkürler. Henüz Sim Shield im yok ama en yakın zamanda bunu nrf24l01 ile birleştiricem. Yorumun için teşekkürler. :)
