So i just don't know how to go about doing this... I'm still kind of new when it comes to programming, so I need some help. I'm trying to store RFID tag codes in the EEPROM, but I know you cant store letters. I read somewhere that you also have to split the ID number into 5 sections of two characters and then store them that way, but I don't know how to split up the numbers or convert the letters into numbers. Any help is appreciated. Thanks
