I'm looking for a way to use Arduino UNO's as serial outputs or input "individually", I don want to have an RX pin for each TX pin. I know the library SoftwareSerial, but I'm not sure if it is posible to achieve my objective with it.
I have also read that in this library "If using multiple software serial ports, only one can receive data at a time". Is there any library or method I can use to achieve both of my objectives, using pins "individually" and receiving data from more than a pin at a time?
Thank you for your time.
