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);





void loop()


state =;

if (state == '0') {



if (state == '1')

{ tone(8, 15000);





Step 5:

vedio will be there by nxt week
