Introduction: TV Remote Jammer

Picture of TV Remote Jammer

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....

Picture of 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

Picture of 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...

Picture of 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...

Picture of Putting All Together...

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

Step 5: HOW TO USE...

Picture of 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.......

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....

how it cab be used on cell phone ?

means???,sorry I didn't get you

Rurik Man (author)2016-08-03

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

The arduino mini can be easily found on eBay...

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!

Great idea,will use that!!!!

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...

imcp1024 (author)--scientists--2016-06-17

it makes the TV remote not work.

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

you can make it using a 555 also,may I send you the diagram....

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.

yup,you said that right..

--scientists-- (author)2016-06-17

What do you use that for??

for fooling around people in my house....

If the trick is to send ir invalid codes, you don't need an arduino, a quad nand is enough.

But my friend that is not available here in my town,so I prefered to use Arduino,anything that can blink an IR led in every 12 microseconds can be used...

How about a 555? if it's just every 12 Ms, don't you just need the right resistor?

yes,I thought about that but I wanted to make a circuit a simple one,555 would be to complicated for beginners,my next instructable will deal with this only....

jekob (author)2016-06-16

it really work?

Daniyal Shamsi 154 (author)jekob2016-06-16

yes,it does...

VincentK22 (author)2016-06-16

Do we have to use the Arduino Mini or can we also use the Arduino Uno.

I am not really good at this kind of stuff as I just started, It would help me out a lot.

You can use Arduino uno,there will be no change in the program just upload this one only,connect the ir led on pin 12 on uno,I used mini just to make it compact
