    I want to know, if RFID reader provides TTL output of 5V even then i have to use RS-232 for interfacing? Can we directly connect with the reader module with rx, tx and ground pins?

     

    I am making my final year project on RFID based attendance monitoring system in which I am using RFID reader along with LCD, EEPROM, RTC.

    I am getting stuck in c-programming. I would be very grateful if someone helps me in providing codes for it.

     

    Thanking you in advance.

    rf module is ttl compatable..u can directly connect it to microcontroller…no need f any line drivers

    you need to interface another max-232 to your microcontroller.then you can connect the max232 of rfid reader to the max 232 of microcontroller.
