RFID INTERFACE

[Shreevatsa Y S]

I have made interface of rfid using at89c51 project as you have suggested in
your website. But it is not displaying anything.
I have used rg1602a v2.0 lcd display. Is it same as the lcd in your project
or different. Is that the problem.

Please let me know how to troubleshoot the problem.

check your wire connection with LCD.due to loose connection, voltage fluctuation introduced.
