Hi. I have assemble the components in PR 25. But unfortunately i`m experiencing some problem. When i switch on it displays "user not found" wheres in the detail description it says it supposed to display "place your tag". Some times it displays "Place your tag" but after few seconds it shows " user not found" again. I would be glad if someone can help me resolve this problem. Thanks in advance.

i have checked the connections. I am pretty sure its according to the schematic diagram. Can faulty of component cause this? I tried replacing the IC and even the crystal. Still no difference. But when I tilt the breadboard it displays "place your tag" for sometime and resumes back to "User not identified".

Never tried that DIY before, but looking at the short description. It is about RFID reader.

Again, I would request to show us a photo of the hardware, the clearer the better 8-)

OK, if you are doing project on breadboard, there are too many unstable connection.

You will need to check the connection and based on your description, you should focus on RFID connection. I don see any RFID connection too.
