Introduction: Low Cost Arduino Jammer 433 Mhz

Introduction

In this project I will demonstrate the use of an arduino
as a jammer for the range of 433 Mhz using only 2 element´s

List of
materials:

-Arduino

-433 RF Module

Step 1: Project

For this project I use one breadboard but you can
simple connect the RF transmitter to the arduino, and also you can get the
power from the arduino board, I use 12 Volts.

The arduino will generate one square wave and it will
feed the RF module

I get the spectrum using one RTLSDR at the distance of
2 meters from the antenna

Step 2: Spectrum of the Arduino Jammer

Step 3: The Test

The test
was conducted using as an reference an CAR KEY, The typical spectrum of 433 Mhz
car Key is in figure A, the scale is in
db, the measures were taken using one RTLSDR Pen

Step 4: Where Is Wally ???

After I turn on the arduino and I press the car Key I get the spectrum of figure...

Where is the signal Key..

Step 5: Code

And now the best part .. the source code of arduino ;

--------------------------------------
void setup()

{
}
void loop()
{

tone(8, 15000); // generate square wave

}

    Really great project could you send me the full source code please . barryjoneill1@gmail.com
    Also ive seen this being done with the use of a NE555 square wave oscillator without the use of Arduino but its a great starting point well done

    You can increase the range of the jammer? using an amplifier?
