Introduction: Phone Controlled Signal Jammer

About: time passing when in mood, do crazy stuff with friends and occasionally with gaming stuff and arduino and beagle bone

Every one has the tiny feel somewhere in their mind to be a hacker!

so today lets do a small hack of blocking a phone signal remotely using only 4 elements

Step 1: Required Things

> Arduino uno x 1

> 433 RF Module

> HC06 (bluetooth module)

> Any android phone (which can run the MIT app inventor)

Step 2: Connecting Elements

connect them as shown in picture

Step 3: Android App

using the bit app inventor, easy to use and fun

source code = picture

the program explains itself

one button connects to hc06

2 more buttons for on and off

the skull is to show the power

Step 4: Arduino Code

#include (SoftwareSerial.h>

SoftwareSerial mySerial(0, 1);

char state;

int LED = 13;

void setup()

{

pinMode(LED, OUTPUT);

Serial.begin(9600);

mySerial.begin(9600);

digitalWrite(LED,LOW);

}

void loop()

{

state = mySerial.read();

if (state == '0') {

noTone(8);

digitalWrite(LED,LOW);
}

if (state == '1')

{ tone(8, 15000);

digitalWrite(LED,HIGH);

}

delay(100);

}

Step 5:

vedio will be there by nxt week

i made one, it doesnt work. it makes sense, as the rf module works in 433mHz and a typical 4g/3g sinal goes within 850 to 2100 mHz.

hay un error el modulo Bluetooth , funciona con 3 voltios , el modulo 433 solo trabaja en esa frecuencia 433 mhz y el programa esta echo en Scratch, no se les ocurra conectar el modulo a los 5 Voltios , ya que arduino tiene un salida para 3 voltios

Dude this is awesome. What exactly will it do? Just make it impossible for someone to be able to call and text? Or can we see what they are doing? Thanks.

this blocks the signal that is received by a phone which is in a radius of 20m is a proper antenna is kept

this was very useful from making my mom's phone from getting my academic info message to her phone
