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.
