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.
