Atmega 328

Hello arduino people .. :D

i will use atmega 328 and Maybe i think true, maybe wrong but,

as i understand atmega has 1 RX and 1 TX But i need 2 RX ..

  • How can i do that ? can i change one atmega pin to RX ?

  • Is there any suggestion ?

thank you have a good arduino


There is a software serial library that should be of use to you.

Even better would be to use the NewSoftSerial library, instead. If functions more like the hardware serial function, with the ability to determine if data is available to read (which SoftwareSerial does not have).

Or use a 644 or mega board (2/3 hardware serial ports)


Thank you all =)

have a good day
