HOMEMADE WALKIE TALKIE WITH NRF24L01 || DIY PROJECT

hey! guys, I am back with another interesting realtime project walkie talkie.

this project is made out of old spike(extension box), NRF24L01, sound sensor module.

I will show the complete details of this project. 

COMPONENTS REQUIRED:

1. ARDUINO.

2. NRF24L01 TRANSCEIVER.

3. SOUND SENSOR.

4. AUDIO AMPLIFIER.

5. SPEAKER.

6. STEP-UP BOOST CONVERTER.

7. LITHIUM-ION BATTERY.

8. ON/OFF SWITCH.

9. PUSH BUTTON.

10. ANY PLASTIC CONTAINER.

CIRCUIT DIAGRAM:

SOURCE CODE:

#include <RF24.h>

#include <SPI.h>

#include <RF24Audio.h>

#include "printf.h"    // General includes for radio and audio lib

RF24 radio(7,8);    // Set radio up using pins 7 (CE) 8 (CS)

RF24Audio rfAudio(radio,0); // Set up the audio using the radio, and set to radio number 0

int TALKBUTTON = 3;

void setup() {      

  Serial.begin(115200);

  

  printf_begin();

  radio.begin();

  radio.printDetails();

  rfAudio.begin();

  pinMode(TALKBUTTON, INPUT);

  //sets interrupt to check for button talk abutton press

  attachInterrupt(digitalPinToInterrupt(TALKBUTTON), talk, CHANGE);

  

  //sets the default state for each module to recevie

  rfAudio.receive();

}

void talk()

{

  if (digitalRead(TALKBUTTON)) rfAudio.transmit();

  else rfAudio.receive();

}

void loop()

{

}
