    Here is the new code for lib 2.0, but I am having some problem with initialization of rc522. I connected RST tu D7 and SDA to D8. Any idea what to look for?

    /*
    * ----------------------------------------------------------------------------
    * This is a MFRC522 library example; see https://github.com/miguelbalboa/rfid
    * for further details and other examples.
    *
    * NOTE: The library file MFRC522.h has a lot of useful info. Please read it.
    *
    * Released into the public domain.
    * ----------------------------------------------------------------------------
    * Example sketch/program showing how to read data from a PICC (that is: a RFID
    * Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface.
    *
    * When the Arduino and the MFRC522 module are connected (see the pin layout
    * below), load this sketch into Arduino IDE then verify/compile and upload it.
    * To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M).
    * When you present a PICC (that is: a RFID Tag or Card) at reading distance
    * of the MFRC522 Reader/PCD, the serial output will show the ID/UID, type and
    * any data blocks it can read. Note: you may see "Timeout in communication"
    * messages when removing the PICC from reading distance too early.
    *
    * If your reader supports it, this sketch/program will read all the PICCs
    * presented (that is: multiple tag reading). So if you stack two or more
    * PICCs on top of each other and present them to the reader, it will first
    * output all details of the first and then the next PICC. Note that this
    * may take some time as all data blocks are dumped, so keep the PICCs at
    * reading distance until complete.
    *
    * Typical pin layout used:

    This sketch is to open a Garage door with an mifare RIFD-tag
    
    For an Arduino Nano v3
    Connection wiring :
    - nrf24l01+ as descibed on the MySensors website
    - MFRC522 reader/writer as described above EXCEPT for pin D9 and D10:  connect RST i.s.o. pin D9 to pin D7 and connect SDA(SS) i.s.o. pin D10 to pin D8
    - LED with 470ohm resistor between GMD and pin A3
    - push button between GND and pin D5
    - 5v relays coil between GND and  pin D4 -> switch pins of the relays should be connected in parallel with your garage door push button.
    
    Features:
    This project can record up to 18 RFID-"tags"
    These card IDs are stored in to EEPROM by keeping them next to the RFID reader when the system in program mode. (Slow blinking LED) When a card is accepted as new card the LED will blink fast for a short time.
    To keep the master-tags (choose your own) next to the RFID reader when pressing the push button. To clear all cards (except the master card) press the push button in program mode for 6 seconds. The LED will now fast blink for a couple of seconds.
    
    Your garage your can be opened by keep a registered RFID tag next to the reader or by clicking the open icon on lock node presented by this plugin.
    By by-passing the alarm node presented by this plug in the RFID will be temporarily disabled.
    When an incorrect (not registered) RFID tag is scanned the alarm is triggered to detect illegal scan attempts

    @gohan did you try running the MRRC522 demo application only?

    So eliminating all MySensors stuff. To check the wiring.(make sure the pin 7 an 8 definition are correct.)

      If I unplug the nrf24 and use the original wiring with the demo sketch I can read the tags. I checked with multimeter from arduino to the rfid pins and they are OK. But I'll be ordering the newer board that supports nfc

        Hello all,

        I am very new to arduino and all this stuff. This rfid garage opener ist exactly what i am lookibg for as my first project. But i have problems compiling the code with arduino ide. I get error notifications regarding the .h files. Do I have to include them in my arduino ide folders? Can someone please tell me where to find them? And where i have to save them?

        It would be very nice if someone helps me!

        Thanks

          It would help if you share your error messages.
          In general I would say, read the messages and (try to) interpret them (google?).

            @thomas84 of course you need to install the libraries from library manager for all the Includes

              Hello all,

              I am very new to arduino and all this stuff. This rfid garage opener ist exactly what i am lookibg for as my first project. But i have problems compiling the code with arduino ide. I get error notifications regarding the .h files. Do I have to include them in my arduino ide folders? Can someone please tell me where to find them? And where i have to save them?

              It would be very nice if someone helps me!

              Thanks

                Hello all,

                Thanks for your answers! Yesterday I could finish the uploading to the arduino nano. Now I wanted to test the garage opener and did the connections like in the picture at the top of this. But nothing is hapening 😞 Even the red light led ist not on. Do I have to "start" the programm some how?

                Thanks for your help!

                  I got issues too when I tryed the MFRC522 and couldn't get it working with the NFR24, you might have better luck using the I2C model

                    Why is the NFR24 needed at all?

                        Are you looking for an rfid system or just a radio remote control?
