I am using an Arduino Mega. I was wondering if it is possible to use the RX on a serial port while not using the TX. In other words I'd like to use the TX pin for something else and I'm only using the serial port to receive and don't need to transmit. Is this possible? Thanks for any replies, Digi…

Question about serial ports.

Are you using ALL the digital IO on the mega?
