Tutorial 12 for Arduino: RFID Card Reading

| 165 Comments

Finally! It’s been about 3 months since my last arduino tutorial – I’ve been keeping busy as usual. I’ve been working on this one for some time. I got the parts months ago, made an outline a few weeks ago, prototyped the circuits and wrote the code last week, and did the filming over the last few days. I’ve upped the ante for my production capabilities on this video. I’m using two cameras (A Canon Vixia HF11 and a Canon EOS Rebel T3i Digital SLR), a fancy new Rode Shotgun microphone, and more tripods! I’ve also implemented some improved audio processing on my voice-overs, so let me know what you think!

RFID technology is really really fun in my opinion, and I’ve been wanting to implement it in a project for some time now. However, doing that can be challenging. But, thanks to the tutorial below, you should have no problems putting together a simple RFID-based security system! I explain the physics of how RFID works in the video, but if you’re a physics nerd like me, and you’re hungry for more, be sure to read up on RFID on wikipedia. In this video, I’ll explain how to setup an RFID reader (like this one) with your arduino, read some serial numbers, and use that data to make a secure entrance database.

  1. Hi,Can you guide me to read RFID tags and compared with database mysql? Thanks

  2. Hi Jeremy, I wanted to say thank you for the arduino tutorials, they were very helpful and informative. Being that I am very new to this and such a beginner, I’m having a difficult time understand how to set up, attach or code it all so it all works =(

    I am in the process of building a costume and would like to add electronic like an Arduino board to control the lighting, movement, and sound to give it that “wow” factor.

    I wanted to ask if you wouldn’t mind offering some assistance and guidance to help complete the project further. I’m sure what I would like accomplish would not be to difficult for you, but honestly, being a beginner, this is completely over my head. Any assistance you could offer would be greatly appreciated.

    Sincerely,

    Greg
