Program Code:

Transmitter Code:

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
byte data[1];
const uint64_t Pipe = 0xF0F0F0F0A1ll;
RF24 radio(9,10); // CE,CSN:

void setup() {
Serial.begin(9600);
pinMode (7,INPUT_PULLUP);
radio.begin();
radio.openWritingPipe(Pipe);
  // put your setup code here, to run once:

}

void loop() {
if(digitalRead(7)==HIGH){
data[0]=1;
}
if(digitalRead(7)==LOW){
data[0]=0;
}
radio.write(data,1);
  // put your main code here, to run repeatedly:
}

Receiver Code:

#include <SPI.h>
#include "RF24.h"
#include "nRF24L01.h"
#include "Tone.cpp"
byte data[1];
boolean var;
const uint64_t Pipe=0xF0f0f0f0A1ll;
RF24 radio(9,10); // CE,CSN:

void setup() {
Serial.begin(9600);
radio.begin();
radio.openReadingPipe(1,Pipe);
radio.startListening();
pinMode (7,OUTPUT);
  // put your setup code here, to run once:

}

void loop() {
if(radio.available()){
  var=false;
  while(!var){
    var=radio.read(data,1);
    if(data[0]==0){
      tone(7,3000);
      delay(10);
    }
      else{
        noTone(7);
      }
    }
   }
  }
