Hey guys,
I am currently working on a project interfacing a UHF RFID reader with an Arduino UNO. I just have some questions about how the arduino operated. I am new using arduino.
Correct me if I am wrong but I know that the UNO has 1 serial port. When I have the arduino connected to the
computer and initialize the serial lines with the baud rate. Then if I transmit some date using this serial port I can see it in serial watcher.
So i can only have 1 device using UART correct? Would I need to get a Mega so I can have multiple Serial ports so I can have the arduino communication with both PC and RFID reader? Is there a way that I can somehow debug my code for RFID without using the serial communication on the PC?
Thanks.
