  • Ja det korrekt, du kunne også benytte AVR for, at have mere space til rådighed end Arduino, hvilket kræver mere tid og arbejde, men resultatet er fantastisk. Bruger du C eller C++ som programmeringssprog ?

  • @m4unot Til Arduinoen bruger jeg selvfølgelig Arduino IDE hvori jeg programmerer C++.

    Ellers programmerer jeg normalt i C til diverse andre microprocessorer, PIC, ARM mm.

  • Flot, men husk på, at EEPROM har bestemt antal gange du kan skrive/gemme. Du kunne lave det static og bygge trådløst enhed med flash slot.

  • @m4unot Rigtig nok, men det er jo heller ikke meningen at du skal omprogrammere døren hver anden dag! I praksis vil man jo blot programmere døren en gang for alle med de nøgler familien har.

  • awesome

  • Very nice. May I see your code?

  • @lewsut Of course.

    You can see the code at my blog now: blog.tkjelectronics.dk/2011/04­/arduino-rfid-door-lock/

  • Nice project! What happens when the power is shut down? Does it keep all the tags IDs in memory?

  • @FinDavyx Yes. It saves it all in the EEPROM.

  • @FinDavyx

    Hi.

    Yes - up to 3 tags can be stored inside the Internal EEPROM of the ATMEGA chip. The EEPROM can hold a couple more, but we decided to make a demonstration limit of 3 tags!

  • Respect

  • Nice project guys!

  • @lartti83 Thx :D
