Can you help this problem with my Arduino RFID system? Answered
I have got an Arduino RFID system going with a Rfid_RDM630 card reader. This has worked for me for some time, but suddenly I am getting a lot of this "ÿÿÿÿ" in the serial monitor, but I'm also getting all the stuff I should be getting.
I have attached a screenshot to show you.
I have also attached the code, and have been following the instructions of this website. I have followed them to the word, any ideas why it isn't working?
I know that the RDM630 Unit is working as whenever I put a tag up to it the red LED attached lights up.
