Introduction: 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.

Step 1: Upload Code to Arduino Uno.

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.

Step 2: Install Hardware!

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

Step 3: Use and Show It to Your Friends :D

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.

Nicely done.

I think you don't need to use Relay actually, most motherboards' front panel pins use either 5v or 3.3v and an Arduino can handle both voltages. Test it if it works and you can free your relay for other projects.

this is only prototype. i will use transistor in smd pckg and custom pcb etc. no you cant just put 5 or 3.3v because that is signal line for mcu on motherboard and on my is about 2.37v

Actually you just need to ground that signal in most situations.

This is a wonderful idea! I would have never thought about this before!

Why don't you disable the power button and program a second FOB to turn it off?

Because i dont use it always. its nice to show to friends but when i dont have card nearby i use buttom. and same card turns it off

i just dont need separate card to turn on off

At the top you said that their is a video. I am not finding it... Is it because I'm on Android?
