The RFID reciever has a serial female connector
Well i cannot figure out how i can read serial data from the RFID reciever using UNO and then transmit it to the PC and view the data on the Serial Monitor. How can i hook up the Tx from the reciever to the RX of UNO, isnt the RX of UNO reserved for the serial communications with the PC?
but when i directly connect it to the arduino uno RX pin nothing.
i now built a max232 circuit
I am really annoyed by this small problem to which i have no solution... please help
