BEST WAY TO TURN ON PC USING ARDUINO AND RFID || AMAZING

Now i will show you how to make best thing ever with this module :D

Parts:
- Arduino uno
- RC522 RFID Module
- Tags or smart card for module
- Relay Module (you can always build own with led, 5v relay, resistor, transistor and diode)
- Jumper wires

You will also need RFID Library (DHT Library, I2C LCD Library)

Watch demonstration video first.

In future i will add lcd with dht11 sensor and rtc.

I want to said thanks to omersiar for his great projects rfid door lock.

Upload code to arduino using arduino ide. You can always edit code and set time for simulating button press. I set it to 800 ms. You can also change standbypin and relay pin. I recommend to dont change ss and rst pins for rfid.

First you need to find place for rfid module, relay and arduino. I did that under my 3rd cd rom. See pictures.

NOTE: you need to set master card first. so you need 2 cards. when you power it up first time, read card you dont want to use and then read it agin to enter program mode and now read card that you want to use and then agin read master card to exit program mode. Just watch omersiar tutorial. Thanks for reading.
