Example project with the NFC-Bit: http://pv-productions.com/lego-doorlock-system/

With the “Near Field Communication Bit (NFC-Bit)” you can add “keys” to your creations. Its everyday use can be found in door systems, security systems, home-automation, data-transfer, payments and many more… Every NFC-tag is unique! See NFC as a unique electronic key for your littleBits creations. Actions only take place when the right NFC-tag is presented.

You can control the Bit with the 2 included NFC-tags, but also your own NFC-tags (e.g. the pass from the sport school etc.)

With the mode button you can toggle through the 4 modes:

(NOTE: Eventually more modes will be available and more tags can be added when the project reaches 1000 votes!)

1 Program mode:
Program up to 4 different NFC-tags into the NFC-Bit. The built-in memory will save the tag-IDs when the Bit is unpowered.

2 Read mode:
When a programmed NFC-tag is detected, the NFC-Bit output goes HIGH for 1 second.
Non-programmed NFC-tags won’t work obviously.

3 Read mode extended:
When a programmed NFC-tag is detected, the NFC-Bit output is different for every tag.
Non-programmed NFC-tags won’t work obviously.
In this way, when connected to the arduino bit, you can read the different outputs and control different things with the different NFC-tags.

4 Read mode all:
Any NFC-tag on the planet can trigger the NFC-Bit output HIGH for 1 second.

Suggestions, ideas or what you would like to see in the Bit, you can put it in a comment below.

I hope you like it.

    Awesome work, man. I have an RFID bit in my list of bits to try to prototype but it looks like you just saved me a bunch of work. Great project. I voted and shared both of your projects. I hope this and the RGB led bit both make it to production cause I WILL BUY!

    Littlebits, put this bit in the fast track to production

  • dmr over 2 years ago

    This looks awesome! Would be a great way to bring some Disney Magic Bands magic into my living room, or even reuse some NFC keys from hotel rooms from business trips.

    Just came across another great use for the NFC-Bit. For the Pet lovers atleast;)

    Wonderful , i want it !!!! I really want it !

  • icco about 2 years ago

    This sounds awesome. I'd love to be able to tap my android phone to this or something, to then trigger something.

    i can make physical minecraft skylanders!!! woohoo!

  • marwansharaf over 1 year ago

    MUST HAVE!!!
    one of the BEST BITS ever!!!!
    I can make a hotel keycard for my bedroom instead of carrying heavy metal keys (^-^)

    • Philip Verbeek PV-Productions over 1 year ago

      Great idea!!! The NFC Bits are available at http://pv-productions.com/littlebits-nfc-bit-near-field-communication/
