I recently ordered the Sparfun RFID Reader and I am using an Arduino uno to power this. I also have RFID tags - AD-665u8 and it does say that they are Gen2. However, whenever I run one of the example codes on Arduino, it keeps saying “searching for tag” but never finds the tag. My connections right now are 5V, Gnd, pin 2 and 3, that is all I have connected. Is this something you could assist me with? I am not sure why the tags are not getting detected?
