I've been trying to get an RFID reader to read an RFID card with the past while yet to no avail. I'm pretty certain that I have everything connected properly on the breadboard and to the RFID reader and Arduino board.
I'm getting the following error when I upload from the Arduino software to the board... 'Problem uploading to Board'. I'm just getting the follwing output:
Binary Sketch size: 5632 bytes (of a 14336 byte maximum)
avrdude: stk500_getsync(): not in sync: reap=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, reap=0x51
If anyone has any solution to the problem I would appreciate it greatly. Sorry if the description above is a little vague... but I'm afraid I'm not much of an electronics or coding expert
I don't know about your unit, but when I use my RFID unit I have to unplug the antenna, upload the sketch and then plug the antenna back in to get the sketch to run correctly. Might be worth a try.

Cheers for the reply. Still no joy though, unfortunately.
I should also add that since the original post the sketch is now uploading to the i/o without any problems. But I'm still confused as to why I can't get any readings from the rfid card. I also received some rfid tags this morning so it would be great to crack on and get some communication going between them and the arduino.
Could anyone recommend a basic sketch to get a test reading from the rfid card or tags? Much appreciated.
