    i used a program for interfacing RFID and AVR mc from your site. The first line on LCD is correctly displayed but when the RFID section comes the LCD is not displaying the correct sequence, some other letters and symbols are getting displayed.

    Hi Hafeez,

    Check the baud rate of the RFID module which you are using.
