i am using rf module that i bought from robokits

http://robokits.co.in/shop/index.php?main_page=product_info&cPath=7&products_id=414

i have read its product manual and done according as it is given in manual but i am not able to properly make communication between two trans receivers .
i am using arduino uno and duemilanove.

code for transmitter is:
void setup()
{
Serial.begin(9600);

}

void loop()
{

Serial.println(40);
delay(2000);

}

code for receiver is:
void setup()
{
Serial.begin(9600);

}

void loop()
{

if(Serial.available()>0)
{
int a = Serial.read();
Serial.println(a);

}
Serial.flush();
}

i am getting only junk values in serial monitor.
additional info: i am using it in default mode i.e baud rate :9600 , powering up using arduino and connecting only gnd,vcc txand rx. I have made proper connections as given in manual.

you need to use virtualwire library for data transmission wirelessly.
virtualWire library is available in built in library folder of arduino.

arduino-1.0.5-windows\arduino-1.0.5\libraries\VirtualWire

use VirtualWire library Examples codes for understanding and for data transmission and reception.
