I have an RFID reader but each time I turn on the Arduino I have to unplug the RFID RXO Line for a second. Once I put it back into the board the reader will work until I turn off the Arduino. Is this normal and is their any way around it?

Also, i'm using a MEGA 2560 and Pin 0.

Perhaps I did not explain my problem well. I have posted a link Illustrating how the RFID Reader hooks up to the Arduino. Although I have a mega and i'm not using the LED's the rest is the same. What I have to unplug is pin 0.




You are using pin 0 for the RFID, this is the same serial port as the connection to the computer.
When using a Mega you have three other serial ports, you should use one of these, then you can look at debug information as well.

Thanks I will try that.
