Introduction: TURN ON LIGHTS WITH RFID CARD

By

Hi guys! Today we are going make Rfid Card controlled light switch.

When we show first card to reader lights will turn on. When we show second card lights will turn off.

Also you will learn what is the EEPROM.

Let's start..

Watch the video. If you have a problem, you can add a comment..:)

Step 1: What Will We Use?

  • Arduino
  • RFID Module
  • Relay Module
  • Breadboard

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

Relay To Arduino;

Gnd to Gnd

Vcc to 5v

Signal to D7

Step 3: EEPROM Using;

You will see 2 different code in data. What should you do?

  1. Firstly you should upload the ''rfid_setup'' code,
  2. Open the serial monitor
  3. You have to show 2 different idcards in 2 different times
  4. If you done this work, you can upload the second code to your Arduino
  5. Finally you can use your device.

Step 4: Code Download Link:
