I have recently gotten a Parallax RFID reader and I was trying to make it work with my Arduino uno. I have gotten all the necessary wires attached and I used a RFID reading program I found from Make (I will put the code at the bottom). When I open serial monitor and move an RFID card near it, it spits a series of x's and ø's(eg. xxxxøxxxxøxxøø). I am expecting to see a combination of letters and numbers. I think its a problem with the code, but I dont know enough about it to know whats wrong.
