Use only one pin as serial output/input with arduino 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.
AVR304, "Half Duplex Interrupt Driven Software UART on tinyAVR and megaAVR devices" describes how to implement a half-duplex software UART using 2 pins. Simply omit the half of the UART that you do not need in your own implementation.
