I'm new to arduino. In my project, i need to connect a gps,one rf transmitter and one rf reciever to arduino uno board.But i can find only one rx tx pins in uno.So, how can i connect these three devices to arduino and do switching between them??Someone pls help...

You can use Software Serial to connect the GPS.

Or you could use an SPI based RF transceiver like the nRF24L01.

Or you can use the Hardware port from uno and use the SoftwareSerial for the rest see here http://arduino.cc/en/Reference/SoftwareSerial

Which RF transmitter? Which RF receiver? Which Arduino?

The devices i referred to are arduino uno,rf ransmitter 433 Mhz ASK and rf reciever  433 mhz ASK.
