  • RFID+Relay+RFID Door Lock Code = RFID PC Switch! over 1 year ago

    Hello and thanks for the comment! ♥ Hmmm... Interesting question.

    I guess it's not possible, because RFID readers (and cards) are usually added for security features, that's why you can't just use any RFID card without registering it first.

    However, I think it's possible to modify the code to automatically store your RFID card's data on to the Arduino or an SD card after reading it to make it usable right away.

    The only problem is that I haven't tried it yet.

    Sorry.

  • LED Matrix + Motion Sensor Door Display [Arduino Holiday] about 2 years ago

    Hello, Buddy! Thanks for the comment! ♥

    I used a generic PIR motion sensor. I believe it's an HC-SR501, if I'm not mistaken.

    Not sure about the mini one, tho, since I haven't tried it yet.

    As I have said on the video, I chose a higher amperage power-supply for future project updates, like adding more matrices or something like that.

    Yeah, I did not add any capacitors on it, but I have added a 470 ohm resistor on to the data lead and I forgot to add it on the schematics. My bad.

    Apparently, it's called 2-Step Authentication.
