Hello, I'm new here.
I'm trying to connect a rfid reader device to my Arduino mega. It has a USB connector which works when connected directly to the USB on the computer. However, I want the RFID reader to interact with my Arduino, and plan to use the RS 232 pins to do so.
The reader has RS 232 TXD and RXD. Question is, can i connect the RS 232 TXD RXD to Arduino's TX RX pins?
Thank you in advance!
