Android Jammer Control


I am a lazzy person, i need one remote control for the jammer and i have one HC06 lying around and my android phone, in this project I will demonstrate the use of an android phone as an remote control for my 433 Mhz jammer arduino using only 3 element´s, KISS theory

List of materials:

-433 RF Module

-HC06 (bluetooth module)

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Schematics

For this project I use one breadboard, but you can simple connect the RF transmitter and the HC06 to the arduino, pay attention to the connection of HC06, arduino port RXD-> TXD HC06 and Arduino port TXD->RXD HC06.

The power comes from a 12 volts battery and don´t forget to connect the 5 volts power source to hc06, if you conect to 12 V you kill it

Step 2: The Android /arduino Code...

For programing the android i use the MIT app inventor, its easy to develop and have what i need.

the program explain´s by himself, one button connect´s to hc06,
and more two buttons for the remote controle (ON OFF), the skull is just to remmind about the consequences of using this jammer outside the lab.

Arduino source code

And now the source code:

#include SoftwareSerial

mySerial(0, 1);

char state; int LED = 13;

void setup()

{ pinMode(LED, OUTPUT);

Serial.begin(9600); mySerial.begin(9600);



void loop()


state =; if (state == '0') { noTone(8);



if (state == '1') { tone(8, 15000); digitalWrite(LED,HIGH);

    No error if to write so

    #include <SoftwareSerial.h>

    SoftwareSerial mySerial (0, 1);

    code in my arduino one doesn't work...

    #include SoftwareSerial
    mySerial(0, 1);

    i think the problem is library..

    sketch_jul22a.ino:1:10: error: #include expects "FILENAME" or <FILENAME>
    sketch_jul22a.ino:3:1: error: 'SoftwareSerial' does not name a type
    sketch_jul22a.ino: In function 'void setup()':
    sketch_jul22a.ino:10:21: error: 'mySerial' was not declared in this scope
