hello, everyone. i am shubham. i want to interface gsm,gps, fingerprint sensor to a arduino uno. This all three requires serial(UART) protocol , but there is only one hardware serial port is available on arduino uno.( i.e. on pin 0 and 1) Now i come across Software serial port. so my question is, Can i use more than 2 software serial port on arduino uno?

Did you read the SoftwareSerial documentation?

Get a Mega.

Possibly, in theory. Not in practice.

You may be able to use SoftwareSerial alongside my Yet Another Software Serial. If you have the time it might be worth trying before you spend money on the Mega that @PaulS has recommended. The Mega is the sensible solution.
