Arduino key fob reader My question is: can rfid shield (RDM6300 125Khz) detect 1mm to 10mm of movement, let arduino mega/nano know about that movement, so the arduino would do 'Thing A'. The log is there in case there was an incident. 99 $ 8. The RFID tags, i. Hardware Setup: Arduino Uno MFRC522 RFID Reader Standard SPI Connections: RST -> Pin 9 SDA The module successfully scans blue key fob tags but does not scan white RFID cards. Skip to. 56MHz, compatible with PN532 and RC522 Reader; RFID kit with 1 RC522 Reader, 5 RFID key fobs, 1 RFID card; DIYables Infrared IR Hi, Is there a way to encode the card used for the RC522 RFID module so that copying the card will invalidate that copied card for the target reader software? I'm thinking that, as each card has a serial number, doing an operation on a set of bytes resident in the card programmer interface using that unique serial and posting the result to a set of bytes on the I need it to lock when the rfid is aproximetely 4 foot away from it and unlock at closer proximity. In order for the RC522 to work properly with Arduino, we need to When a valid key fob is present from one of the pins going high. Good suggestion about using hardware serial for the Bluetooth.
