Hi i am not sure if u can help but for some reason when i use try and do the hexadecimal stuff only some values get read and if so its just 0 on the serial monitor

[@cabbagelover89]

I am also having this problem.

[@windowcleaner-t6u]

Same

[@diaxx9999]

here is the code for lazy ones : #include IRrecv IR(3); int ledPin = 8; void setup( ) { // put your setup code here, to run once: IR.enableIRIn( ); pinMode(ledPin, OUTPUT); Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: if(IR.decode( ) ){ Serial.println(IR.decodedIRData.decodedRawData, HEX); if(IR.decodedIRData.decodedRawData == 0xEA15FF00){ digitalWrite(ledPin, HIGH); } if(IR.decodedIRData.decodedRawData == 0xF807FF00){ digitalWrite(ledPin, LOW); } delay(1500); IR.resume( ); } }

[@EnjoyMechatronics]

Thanks 😊

[@AllanWallsPhotography]

Another excellent video presentation. You manage to include every project detail and give the information clearly and succinctly, without a wasted word. Great job!

[@EnjoyMechatronics]

Glad it was helpful!

[@minhkhoanguyen1407]

can i borrow your code please

[@yasinkotere6578]

I kiss your heart, brother. I have been trying to set up this damn remote for about two hours and no complicated approach or solution from the Internet seemed help, except for your coherent, simple, and logical code. May your problems go away like mine.

[@ernestorodriguez4742]

Very good. This method works. It did not work with other method always giving FFFFFF. This code worked for me with version 3.5.2 #include IRrecv IR(3); void setup() { // put your setup code here, to run once: IR.enableIRIn(); // Cambiado de enableIRIN a enableIRIn Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: if (IR.decode()) { // Cambiado de If a if Serial.println(IR.decodedIRData.decodedRawData, HEX); // Cambiado de IT.decodeIRData a IR.decodedIRData delay(300); IR.resume(); } }

[@williampicca5138]

Thank you so much. It's quite something when I spend hours trying to figure out how to set up my own IR Remote, but nothing works. Then I came across your video, followed exactly what you did, and it ended up working! Once again, thank you!!!!

[@aboudyx]

can you pleas copy the codes i need it why you do that the Ir reciver senser flame up😥

[@二一-m4b]

you are the best 👍 i search many tutorials , no one works finally , i watch this this really works just look at the way you code this can tell that you totally know these

[@EnjoyMechatronics]

Glad I could help

[@lovrosibenik1070]

Can someone help me with my project? My plan is to control servo with IR remote control do rotate it and to control DC to speed it up or slow it down to use it like a fan.

[@siAppDesign]

Your video help me to make it work, thank you. the fact that you also mentionned the library version really help. I guess many people has trouble with it because there is incompatibility between the code suggest and the library version currently install on their system

[@EnjoyMechatronics]

That's absolutely right ✅

[@Voytako]

It didnt work and my resistor and the sensor is fryed, and it all good conected so dis like

[@Anchannel944]

HI, Thanks for the vid. I've tried 3 different remotes and recvers, but every time I get FFFFFFFF, and I don't know why. Please help. Thanks.

[@TacoAlligator]

Make sure your monitor is set to 9600 baud otherwise it might show up weird

[@insanity8692]

Best Tutorial i could find on KZbin. Many Thanks!!!

[@EnjoyMechatronics]

Wow, thanks!

[@AgentEmerald0028]

can you add a file of this code so that we don't need to copy literally everything you've done?

[@oficinarscarservice]

Fantástico!! Ganhou um seguidor!!! Estava com dificuldade em fazer isto funcionar com outros sketchs, qualquer tecla pressionada sempre retornava 0FFFFFFF (delay configurado era de 100 ms, será isso?). Seu método foi o único que funcionou. Muito obrigado.

[@ernestorodriguez4742]

obrigado

[@alexpaul8942]

Hey, I’m having a problem with the code. I am writing it for a passive buzzer instead of an LED, and i have two if statements. i have the same code except for a tone() function. i will press one button and then it will never turn on again.

[@chickencow1598]

mine says 0 in the serial monitor can someone help

[@mihmih-c8z]

tf armin arlert is making code library

[@scorpionesc9999]

first to say , your video is really cool, most simple and clear, congratulation for that. i enjoy to read out the codes from the remote, but unfortunally i cant find your libary today. my IDE is 2.0.2 and thre is no matching libary you use. used HW is same. do you have an idea to get your good libary into mine IDE?

[@EduTechNeer]

Thanks man. I was really stuck on this lesson for the IR remote. I think I got it nailed down now.

[@EnjoyMechatronics]

Glad it helped!

[@stevielut8596]

I want to ask you , can you tell me where you get that like code like that "decode "IR " , I mean where , I have been. searching it , please reply , thanks

[@justanothererd01]

Cool tutorial! One question, what is the name of the song from your intro? It's BANGIN!!!!

[@TacoAlligator]

In your serial monitor, make sure to set it to 9600 baud at the bottom otherwise you might end up with something odd showing up

[@kudakwashemudzingwa8660]

Hie thanks for the straight forward tutorial but am having a problem with the HEX of each remote button, when l press the same button l get a different HEX number , what could be the problem???

[@weizhu716]

check your library , install the newest one

[@welcometochiles6156]

Could be the library like weizhu said, but I have another theory since I'm on the latest and have the same problem unless I blast the remote right into the receiver: I think any interference with the receiver messes with how the receiver decodes the remote, thus different results.

[@spinningcube128]

CODE: #include IRrecv IR(2); int led = 8; void setup() { // put your setup code here, to run once: IR.enableIRIn(); pinMode(led, OUTPUT); Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: if(IR.decode()){ Serial.println(IR.decodedIRData.decodedRawData, HEX); if (IR.decodedIRData.decodedRawData == 0xE916FF00){ digitalWrite(led, HIGH); if (IR.decodedIRData.decodedRawData == 0xE619FF00){ digitalWrite(led, LOW); } delay(1500); IR.resume(); } } }

Hi everybody. I'm currently having a problem and need your help: When receiving the remote's external signal, the VS1838B module only displays 0xFFFFFFFF How to fix it? Thank you Sorry that my English is quite bad

[@joehighpockets]

When I use the cheap remote I also get 0xFFFFFFFF but when I use a XFINITY TV remote I get different codes.

[@zeranimator8500]

If i want to apply it at real lights with high voltage electric power can i directly connect them or should i use a relay for that?

[@EnjoyMechatronics]

No, you have to use a relay module

[@kolyaayrapetyan7048]

Does not work. Very disturbing delay And without it it doesn't work. Please tell me what can be done

[@FictionHubZA]

Try reducing the delay. To 1000 or less than that.

[@FictionHubZA]

Wait. Try increasing the delay. Whichever works best.

[@EnjoyMechatronics]

What happened?

[@abishek_raja_01]

I have one doubt. Is IR sensor and IR reciever is same or different?

[@EnjoyMechatronics]

Yeah, there is a difference IR sensor is a broad term that encompasses sensors capable of both emitting and receiving IR radiation, while an IR receiver is a specialized sensor designed to receive and decode IR signals, commonly used in remote control applications.

Thanks for your interest

[@123masteryoda123]

Your code worked great. I've adapted it to work with a SG90 servo. I need it to move 10 points in one direction or 10 points in the other depending on what key on the remote I press. The only problem I'm having is when I hook up the servo, I get a ton of interference with the IR and it can't read the remote. Even when the servo is sitting idle, I can see numbers all over the serial monitor, and the IR flashing. When the servo is unhooked, it works great (or at least the serial monitor says it does).

[@EnjoyMechatronics]

Most probably this is a power problem, Supply the servos from power source different from the Arduino power source and make sure it has sufficient current rating. Or use the 5 volt Pin to power the servo And the 3.3 volt Pin to power the ir receiver because servos make some noise to the power source and that affects the ir receiver.

Is there a distance away from the arduino that I should limit placement of the transmitter to? I want to place an IR transmitter near the dome light in my car to control aspects of my DSP, but I think the distance would exceed 9 feet from the Arduino to where the LED will go. Didn't know if the signal would be strong enough to go that far. Great job on the video, very easy to follow.

[@EnjoyMechatronics]

Thanks, man I think the maximum distance is about 10 meters.
