Step 1: Function

This project is a working doorbell which the main function is using code to program the arduino in a way where the push button with the transmitter send a signal to the receiving end with the buzzer and receiver which will initiate the doorbell buzz sound with a wireless connection.

Step 2: Step 1: Transmitter Board

How this project is supposed to work is having 2 bread boards and 2 arduiono/genuinos wired to them. for the transmitter board we connect the push button with the 100 ohm resistor connected to ground and a wire connected to power on the breadboard. Then connect the transmitter to the breadboard and wire the button to both the transmitter and arduino as shown in the picture.

Step 3: Step 2: Receiver Board

On the receiver board is where the buzzer goes. Connect one wire to ground through the receiver and connect a wire to a pin of your choice which you can later customize in your code. Connect the receiver to the breadboard and wire it to the arduino as shown in the picture.

Step 4: Step 3: 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);

}

}

Step 5: Step 4: 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


RH_ASK driver;

void setup()

{

Serial.begin(9600); // Debugging only

if (!driver.init())

Serial.println("init failed");

else

Serial.println("done");

RH_ASK driver;

void setup()

{

Serial.begin(9600); // Debugging only

if (!driver.init())

Serial.println("init failed");

else

Serial.println("done");

}

void Play_Pirates()

{

for (int thisNote = 0; thisNote < (sizeof(Pirates_note)/sizeof(int)); thisNote++) {

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

{

Serial.println("Selected -> 'He is a Pirate' ");

Play_Pirates();

Serial.println("stop");

}

}
