TV Remote Jammer




Introduction: TV Remote Jammer

About: I am a 16 year old guy who is passionate about Arduino and programming,I like science but I love programming,I am also interested in robotics......

This is an Arduino controlled TV Remote jammer that comprises of an IR led that sends continuous impulses to TV receiver.The TV receiver does not recognizes the pulse and gets jammed.....

Step 1: Gathering the Materials....

Here is the list of material that you need:

1.Sparkfun Arduino MINI pro

2.9v battery

3.9v battery clip

4.A small switch

5.A small box(optional)

6.Some jumper wires

Step 2: Arduino MINI Programming

We are going to use Arduino Uno to program our SPARKFUN arduino mini,the wiring can be seen in the image above.Go to the tools menu than click on the board and select "Arduino mini or mini pro",then select the port and then upload the program.REMOVE THE ARDUINO UNO'S IC BEFORE PROGRAMMING.

Step 3: The Arduino Program...

Copy paste the following program on Arduino IDE,


//This is a Daniyal Shamsi program in which an ir led is placed

//on pin 12 and is kept near tv,and it blocks the tv remote signals...

int irled = 12;

void setup() { pinMode(irled, OUTPUT);


void loop() {

digitalWrite(irled, HIGH);


digitalWrite(irled, LOW);



Step 4: Putting All Together...

Follow the schematic as shown in the picture....

Step 5: HOW TO USE...

Keep the reamote jammer near the tv(or hide it around,I suggest),switch it on and test it out,fool around people in your house.......


Firstly tried my hands on using Infrared technology,I was successful at my first shot,hope you liked this little Instructable,if so PLEASE VOTE OF ME,thanks to Instructables for creating this wonderful website,a special thanks to SPARKFUN for creating wonderful boards.So if you liked it pleeease throw a vote for me.......

    This is cool.

    More compact than the usual 555 timer design.

    Thanks man!!..The mai reason behind making that was to reduce the 555 complexity and increase compactness(and trouble my sister)!

    Would it work, if the IR was constantly on, and not blinking? Why or why not?

    Great question....,The tv reciever works on the pulses given by the ir remote to perform some action and if the ir led is continuosly on the it might not get a pulse and may ignore it and may catch some other pulse offered by any other remote..The trick is to send an invalid continuos pulse so that it may get engaged in it and get jammed....Sorry for the late reply....

    Where do i get the circuet board used for this? Please??

    Would be a lot of fun in a bar during Stanley Cup season. Use your phone to switch the channels on the bar TVs and then turn this on to stop anyone from changing the channel back!

    Thx for reply. Just one question what does that device do how you fool people with that??

    it blocks the TV remote signals,but which the remote stops to work,and people thing that they are having fault in the remote...

    it blocks the signal sent by the TV remote and people think,there is some fault in the remote....

    Cool, I really wanna make it but I dont have a arduino :(

    When I get the materials, I'll enjoy making fun of my dad and my brother XD

    awesome i made one of these in high school but we did it the hard way. However a cool tip is if you want too check if your circuit is working then simply point a digital camera or smartphone camera at the diode. While infrared is normally invisible with a digital camera you will see the diode pulsing.
