Doorbell Transmitter Code

// ask_transmitter.pde
// -*- mode: C++ -*-
// Simple example of how to use RadioHead to transmit messages
// with a simple ASK transmitter in a very simple way.
// Implements a simplex (one-way) transmitter with an TX-C1 module
 
#include <RH_ASK.h>
#include <SPI.h> // Not actually used but needed to compile
 
RH_ASK driver;
// RH_ASK driver(2000, 2, 4, 5); // ESP8266 or ESP32: do not use pin 11
 
 
void setup()
{
    Serial.begin(9600);   // Debugging only
    pinMode(5,INPUT);
    if (!driver.init())
         Serial.println("init failed");
}
 
void loop()
{
    if(digitalRead(5)==HIGH){
    const char *msg = "a";
    driver.send((uint8_t *)msg, strlen(msg));
    driver.waitPacketSent();
    delay(200);
    }
}
Doorbell Receiver Code

#include <RH_ASK.h>
#include <SPI.h> // Not actualy used but needed to compile
#include "pitches.h" //add Equivalent frequency for musical note
#include "themes.h" //add Note vale and duration

    if (!driver.init())

}
 
void Play_Pirates()

    int noteDuration = 1000 / Pirates_duration[thisNote];//convert duration to time delay
    tone(8, Pirates_note[thisNote], noteDuration);
 
    int pauseBetweenNotes = noteDuration * 1.05; //Here 1.05 is tempo, increase to play it slower
    delay(pauseBetweenNotes);
    noTone(8); //stop music on pin 8 
    }
}
 
void loop()
{
    uint8_t buf[1];
    uint8_t buflen = sizeof(buf);
 
    if (driver.recv(buf, &buflen)) // Non-blocking
    {

      Play_Pirates();
      Serial.println("stop");
  }
