Circuit Diagram:

Arduino Program:

#include <SoftwareSerial.h>

SoftwareSerial HC12(10, 11);

void setup() {

  Serial.begin(9600);            

  HC12.begin(9600);              

}

void loop() {

  while (HC12.available()) {       

    Serial.write(HC12.read());     

  }

  while (Serial.available()) {     

    HC12.write(Serial.read());     

  }

}   

Note:

Transmitter and receiver program is same
