Infrared remote controls are everywhere, you probably have several of them in your home. These handy devices work by sending coded signals with pulses of infrared light to control appliances. We take them for granted, but just imagine using your television or Blu-ray player without one!
In this video, I’ll show you how these handy devices work and how you can capture and decode their codes with an Arduino and some very inexpensive parts. You’ll also learn how to repurpose the remote controls you already own so that you can put those unused buttons to work controlling devices like lights and fans.
I’ll also show you how you can use an Arduino to build your own custom IR Remote Control. Control everything in your room with one button (if that's what you want to do).
Finally, we will see how to use those inexpensive remotes that you can get on eBay to add remote control capabilities to your own Arduino projects. I’ll present a simple project that uses one of those controls to adjust the position of a servo motor. It even uses the “repeat” function that isn’t very well documented.
Here is a breakdown of what we will cover in the video:
00:00 - Introduction
02:20 - How IR Remotes work
03:37 - How to “see” Infrared Light
04:56 - The IR Sensor
06:29 - Decoding IR Remote codes
10:07 - Getting Manufacturers Codes
13:22 - Repurposing an IR Remote
20:37 - Building a Custom IR Control
28:19 - Control a Servo
As always you’ll find an article with all of the code used here on the DroneBot Workshop website at dbot.ws/irarduino. The site also has links to resources you may need when working with IR Remote controls.
Now go ahead and start controlling your world!

Just a quick comment to say, "Thank you so much for sharing your passion and skillset". I have struggled a bit with electronics over the years and I've finally found a like minded person from whom I enjoy learning. Your ability to convey a message with clarity is a gift! Please continue adding content. You are very much appreciated!
As a beginner-level enthusiast I can't overstate how valuable it is to me to get instructions delivered so carefully and clearly. I totally agree with Bill Field's comments below and look forward to many future visits to the DroneBot Workshop. THANK YOU!!!
I have been watching many different channels for quite some time now but this is the first time I've seen yours. The way you clearly and precisely explain everything in detail is excellent, and to be honest, better than most. It makes me believe I will be able to reproduce the results you achieved on my own workbench. I gave you the subscription and look forward to seeing many more videos. Excellent work.
Thanks for this really nice comment Bill, you made my day! Comments like this inspire me to make more videos.
I agree with Bill - very clear!
I'm absolutely agree with Bill, even i'm indonesian i got your explanation so clearly. Thank for your kindness lesson DroneBot.
Fantastic presentation. Best ever. Just the right pace, and all the details covered. And how about the organization in that workshop!
Bill Field same here, it's interesting how different channels that I'm subbed to do things different even though it's for the same area
Once again, You have impressed me. I do not know your professional background, but you make an excellent teacher and an even better video lecturer. You are so organized it makes me ashamed of my own disaster I call a workshop. But, more importantly, you have made these lessons on a rather complex subject 'learnable'. It is so refreshing to see this level of professionalism and expertise still exists. Thank you.
I just love how you say "don't change channels". It's so true.
Thanks you for such a clear and detailed explanation.
I stumbled upon your channel trying to get IR working, there is so many different libraries I trialed but was unsuccessful. I must admit that your video has helped me a lot, and you are a natural teacher. I enjoyed how you explained things and scaffold the hardware and software side of things. I am definitely subscribing to you and have also given a thumbs up. I can't wait to see your other videos, love it. Cheers
Simply incredible lecture!
I wish all the youtube tutorials had at least half the clarity of yours.
I plan to watch all of your presentations; so far every one of them has been either extremely useful or highly inspiring! 👍👍
I've watched a lot of Arduino tutorials and this is by far the most detailed and concise explanation I've ever seen. I'm learning a lot. Keep it up!
I'm a senior in a mechanical engineering program. Myself and 4 other team members are making autonomous delivery system. Thanks for all your videos they help a lot!
I recently found this channel when searching for knowledge about Arduino,this is a superb instructional series and I intend to watch every single one,slowly getting a feel for coding and the sintax required,once again brilliant!!!
Thanks again for another good presentation. Good subject, right level and pace for a broad audience. No waffle, clear knowledge of the subject and first rate visual aids. You are up there with the best on electronics for hobbyists
I have watched a few of your videos now, and I just wanted to comment and say how very professional they are. The content is excellent, well paced, graphics and editing are top notch. Thank you for all the great content you create, it is incredibly helpful.
This is the first video I've watched of yours and I am very happy I did. Instead of just showing what to do, you also explain every step and your code. I really like it and I'm gonna watch more of yours!
I finally found a channel that can explain simply all those questions in my mind that most can't. Thank you by sharing your knowledges to us beginners who struggle to understand some technical areas You demonstrated it in clear and detailed way. Thank you very much. Subscribed!
Another well done presentation. I’ve been using IR remotes with both Arduino and PicAxe and both work very well. I equip O gauge locomotives with the sensor to control the motor(s) and use the codes to automate the engine using an IR LED buried between the ties. Various places along the right of way have different codes.
What the engine does at each LED is written into the program. Some are simple, some complex ..... all are fun! 👌🤗
Woooow ….these are some great teaching tools. Your presentations are excellent. For years I’ve been playing around with the Raspberry Pi. Of course, I’ve come across the Ardiuno but not knowing much about it I’ve kept may distance. After watching several of your videos gave me the knowledge to tackle several of your projects. But more importantly your clean precise presentations gave me the confidence to pursue to the successful conclusion. I now process many many components (resistors, relays, LED’s, sensors. little pieces of hook up wire and the list goes on and on. My wife is concerned about our desk looking sort of cluttered (she actually used more colorful adjectives then I) so I showed her a picture of you workshop from one of your videos and she almost passed out (she really liked the blue peg board). Now she is referring to me with a Compulsive Component Disorder (CCD). Now that I am CCD I’ve fried my first Ardiuno and currently trying to troubleshoot the problem. Can’t find much worth while knowledge on the internet so am studying a downloaded schematic and trying to identifying components. Now …I’ve discovered another rabbit hole. Many different manufactures leads to many different designs around a common CPU and footprint ( in case your looking for a new subject for a video). I can truthfully say that my CCD has reduced my TV time and has really added to my resume but at 74 I’m not looking for a job. Thank you, great job and the video editing and sound is superb, I give you an 11 out of 10.
This is an excellent piece of work. Too much time to prepare the tutorial, the scripting and the sketches. I really appreciated it. Also, I am glad you go deep into the topics. Way to go!
Surely, your channel sets the high water mark of excellence on clear and concise explanations of electronics projects. Brilliant!
Once again, most excellent tutorial. This is a field of control I had not considered before. Easy to understand, easy to program. Thanks so much for another fine, understandable, well-organized session of learning.
Like the previous comment, I am relatively new to your channel, and totally impressed with your clarity in describing the topics you discuss, and access to the information and code on your website. I my estimation you are the best of the RUclips technical educators, I have had engineering professors with less skill and practical knowledge.
I absolutely agree with Bill Field. I just ordered my Arduino and I can't wait to get it. My interest is in robotics, and I'm watching everything I can. You did an excellent job of explaining how the IR works and what I can do with all those old remotes. :) I can't wait to start messing with IR. Thank you so much!
I feel like as soon as I get motors down I can start controlling them remotely.
By far the best and most informative Arduino video I've ever seen! Thank you very much.
I have just no words to thank you , I have stucked into some ir project for many days and your program is just faboulous
Subscribed! Your production, code and circuit example cuts, and demos are so professional! You've really got my gears turning and I have so many ideas for projects thanks to you. Looking forward to many more videos to come :)
Great discussion on using IR devices to control things. Even though you repeat the commands used for the Arduino, I find it helps reinforce the commands and how they are used. I totally hate videos where they play come crazy music while the author quietly swirls the mouse around typing commands without telling you what they are doing. Our train group is interested in using IR sensors on their layouts. This video will be a great help to get them started. Thank you very much!!
Such detailed descriptions are required to inspire the budding engineers sir. You truly are a great source of inspiration. Looking forward to watching more from your side.
A very interesting, useful and well delivered tutorial. From someone who knows, pitching a complex technical subject at the right level so that an audience can understand can be difficult. This was excellent, well done.
Extremely well produced, great communication and content! Thank you so much
Since I haven't seen it in any of your other well-deserved compliments, I'd like to thank you for including a little apropos mild pun before the intro of every video. Cheers, mate!
Thank you for these tutorials. You manage to keep it simple while conveying the knowledge depth that will allow a quick start and go further together. Second video I watch and I am already a fan.
This is the first time I have watched one of your videos, and I have just purchased an Audino UNO plus a 38IR receiver, I did what you said and it all works thanks.
Now I am ready to explore what I can control around my flat.
Thank you for your time. I understand Electronics very well, but get hung up on coding. You explain this very clearly were others run to fast trough it and confuse me sometimes. You get 5 stars! thanks!
I've lost count of how many times I've come back to this video for reference for my projects. Thank you, This is a great useful tutorial
I have spend quite a lot time , listening to your videos, I find it interesting .After reading quite a few times, finally I get some understanding. really informative, keep up the good work!.
This is the best tutorial channel I've encountered! Keep up with the good work Sir
Thank you, that's very kind of you to say.
I appreciate your uploads, everyone that I've watched so far, just the right amount of details, at the right pace, I learn a ton, and get so many ideas. Keep it up, and you might want to add a Patreon link. I think that some people may want to show their gratitude by supporting the channel.
Thank you Treelight, I really appreciate your kind comments.
I've been considering starting a Petreon account as it could help finance some of the components I purchase to make the videos and articles so I may do that soon. I just wouldn't want anyone to feel obligated to contribute as my "mission" is really to help people learn about the subject that I find fascinating.
I'd be interested in finding out what other people might think of the idea.
Very cool! I love how you progress this from a "textbook" example to actual, real world applications. Well done, sir! Very well done. Thank you for sharing your knowledge and time.
I've never seen a video done so well. You explain things very concisely and I am able to understand what you do. I should be able to reproduce your experiments and get the required results. I've subscribed to your channel on RUclips as well as your newsletter after going to your web site. Thank you for all that you do and explaining things so I can understand them.

This is excellent. I could tell by your well organized work space that you understand how to approach a project logically and methodically. Well done. Thank you.
Fantastic! Clear an concise with no extra verbage thrown in. Thank you. This really opens up the possibilities for home automation!
This was the first video I have seen; I check out that you have other videos that interest me; clicked subscribed and the bell.
Thanks for your well made and useful video. I am so tired of youtube click bait and it was refreshing to get your well made videos.
THANKS !!!
I was actually looking for this kind of channel for electrical and electronics. Well, I found the right one. Kudos and subscribed for further more projects like this
Wow, I learned SO MUCH! The other commenters are exactly right - you are an exceptional teacher with an excellent presentation style. Thank you very much for your terrific channel!
After wandering from different channels and watching different videos to find the working I was looking for, your channel is the best please keep making such videos. 👍✌😊
Mr. Shirriff, you're an excellent teacher. I wish I could hang out with you in your workshop and learn all the things you could teach about engineering and electronics.
Ken Shirriff did the IR library for Arduino.
lol. he is not a teacher
You're instruction technique is so thorough and concise! You've definitely been a great resource.
I have a project in mind I could use your help on. It's similar to this in the aspect that I will be using an IR remote and the arduino but I will just be controlling a small motor to open and close a scissor jack I 3D printed to swing my tv out and back to the wall on it's mount for better viewing angle in my room. I'm very new to coding and would appreciate any advice!
Thanks again for producing such a helpful and informative channel!!

Fantastic job. I really appreciate the small details such as the environment, camera angles, conversational tone, and overall delivery. This was a great video to learn from. Thank you.
Hi, really interesting video.
You may have mentioned it and I missed it, but it is important to note that for this to work you need an IR detector with a built-in demodulator that looks for modulated IR at 38 KHz. E.g. the VS1838B. Unlike a normal IR photo-transistor that simply records the pulse, the VS1838B strips the 38KHz carrier returning clean square pulses the the IRremote library can process. Finally note that you did very well to pick the IR detector PCB, as you really need the passive components (resistors and capacitors) that are included in the PCB version. Simply getting the VS1838B means that you need to add the extra 3-4 components on your breadboard.
Also adding a LED (plus a 240 Ohm) resistor to the output of the IR detector, makes the pulses visible so you know the remote control is actually working (don't ask :-)
Keep up the good work, my 11 year old son was hooked and we tried lots of IR stuff.
THANK YOU SO MUCH FOR YOUR GREAT SUPPORTS
A great video! I have learned so much from your series of recordings. I've been subscribed to your channel for a long time. Please keep up the good work. :-)
You are the best teacher there is. So glad to have come across your video. You solved my problem which nobody else could.
Thanks a lot!
I must say you never stop to amuse me with all this knowledge you pass on to beginners like myself well done and Thank you again.
Great video and much appreciated as i am a marine electrician trying to adapt and struggling with code.You make things much clearer .Thanks again
Sir, you are the best in explaining electronics- for sure ! Please keep going that way ! Thank you very much!
Hope you can do a video about the MPU6050, with practical use for such as a self-balancing robot .....
Excelent videos , perfect and easy to understand !
Kind regards from Austria !
You explain things really good
Thank you Saltz!
@@Dronebotworkshop excellent video. Already working on projects to use my remotes on. Probably have questions if I can bug you.
I wish you taught me during my engineering back in 90s, but it's never too late :)
OMG THANK YOU!!!! i tried other videos and they don't give out more details and they were not clear on how to resolve the IR remote or the Bluetooth. Now i got the IR to install and my car is moving with the remote. thank you kudos to you my friend
This was a worldclass tutorial - I can't wait to see what else you got, instant subscribe!
Wow... how did I miss this fantastic channel? Concepts are explained so well!
this is a great tutorial, thank so much really explains everything clearly and is perfect starting point for my upcoming project. Thank you
I agree with Rich D. Everything is so clearly explained, even I can understand it. At age 78 I was brought up on valves transistors and i.cs. for the first time, I can undestand the arduino 'break' function..... Thank you.
you need more subs, I've watched a couple of your videos and you explain everything very well
Keep it up! Love the detail you put into these projects. Very easy for a beginner (me) to follow. Thank you!
Hi Sir Bill / @DroneBot Workshop,
I just finished watching this tutorial and Thank You! so much for your well-explained and very detailed tutorial - I love it!
Your video tutorials are very big help for those people who want to learn or pursue a career in robotics.
I do appreciate your effort in making this tutorial and keep up your very good work!
:) I have already subscribed to your RUclips channel now.
I am from Philippines by the way :)
That was great! many thanks for explaining so clearly also WOW well done on the uber tidy workshop!
Technically the video is excellent, the content is super useful, the explanations are precise, accurate, clear, and most importantly of great quality. I am impressed and very grateful. Of course I liked it and subscribed. If I could do this a thousand times I’d do. Thank you.
This is an absolutely fanTASTIC video explanation!!! I have learned so very much. Thank you!!
Awesome explanation. Thank you very much. I wrote a "Mode Changer Macro" for my TV/PC hybrid monitor. Now I can change the mode immediatly without worrying when my customers come. (I own an Internet Cafe in Turkey.)
This guy's one of thee best at translating this subject.
This video was very informative and helpful, thank you so much!
Thanks for the detailed rundown, you are an amazing teacher. Keep up the good work. Subscribed.
i had been searching for a clear explanation like yours. Thank you so much.😎😍😍
Very well explained!
I've known how to do everything you covered in this video but I enjoyed how you explained everything and make note of safety issues.
Awesome work my friend!
You've earned my sub!
Very glad to earn your sub, thank you very much!
I've just learnt today how complex IR remote integration on Arduino is. I didn't know how to decode the remote control button, and I found your video. So helpful, thank you very much ^^
You are very welcome, glad I could help.
You do such a fine job! Going to use some of the knowledge I gained from your videos for a project I am doing for TTITD event coming up in August.Thanks a Million
Thank you for your excellent and clear explanation. This has been saving quite some time for similar projects of my own. Of course, I have subscribed to your workshop. Happy New Year 2022.
Excellent tutorial !!! One of the best I have seen. Well done as always !! Congratulations !!
Honestly, I love the way you break it down
07:30 "There is this robot IR remote, this is not the one you are looking for." Nice one Bill!
Great video as always. Your tutorials are very easy to follow with all of the visual aids.
I like the video, but I had to give it a thumbs-up based solely on the tidiness of your work space. Little bins stacked to the ceiling, every tool in its place. Remarkable!! Great video also..
I spent lot of time to find these video. There you are. Thank you very much sir❤
Amazing presentations on arduino. You won my subcribe when i watched the ATX power supply video. I wish they would have packaged your videos with those ATMEGA2560 sets i keep getiing. Your videos go through all the cool modules and what you can do with them and you are just doing a damn fine job if i say so myself. Very clean, and it sticks when I hear it from you. I dunno how many of the modules you go through but im bout to watch all of them and like every one.
شكرا لك على هذا الشرح الممتاز وعلى طريقة تقديمك للمعلومه بطريقه سهله وجميله.
اتمنى لك التوفيق.
this is a great tutorial. honestly one of the best if not the best i have found so far!
I've written Industrial Operating Procedures for years (and have PLC Experience), looking to do a couple of projects with the Arduino Uno (which is Greek at this point) I found your video. I commend you on your very detailed explanation(s). Thank you very much for your help.
First video that I watched in this channel, I have subscribed before 30 seconds of the video... Really good video.
Great tutorial. Been looking for the exact stuff you are doing. Been a subscriber for a while. More please. G from the UK👏
Wow - that was very helpful! Thanks! [ATTENTION RUclips: This is the first video that ever got my to buy anything - I followed your sponsored link directly to AliExpress and dropped $5 on a dev kit similar to the one in the demo.]
II like the way you illustrate your projects, and explain so clearly. The code is also explain so you can understand it
I like your presentation and competence very much. It's much better than many companies present their products.
If you want to monetize or get hardware-samples you got best chances to have success. Nice work!
I did the IR experiment and mostly it works just fine. I did find that when you look at the raw input to the IR sensor (using just an ir diode), you usually can tell what the output would be, but then I looked at my Pentax camera remote. The raw is 4 or 5 blips, but the IR code comes out to 8 hex characters and Unknown for mfr code? Most others are as I said before, and can usually be manually decoded. I enjoyed this tutorial.
wow I had to stop the video and get my cell phone out to see the ir light... excellent.. I am wanting to do an IR project.. and need this to get started with my understanding of it all... Thanks Bill.
Thanks for taking time to explain the coding well. Trying to learn the programming and this helps alot. :)
Great tutorial, very clear and well done. I think your workshop is great and wish I had one like it!
Excellent video, Thanks for the step by step explanation of the codes
Amazing tutorial, so easy to follow, keep up the great work!
Initially I got scared of seen the length of the video.Once video started time as faded fastly without my knowledge because I deeply involved seeing your way lecture. EXcellent job DroneBot Workshop
I love this stuff.
I'm glad that I found this video again, because now that I'm into ESP32, I plan on a project to build a universal remote control console device.
Right now, we use Logitech Harmony 650 remote controls for 2 TVs in different rooms.
The problem is, as always, their buttons are failing and I'm not in the mood to do a full maintenance on these things.
Unlike most remotes, these ones are nasty to get apart without destroying them.
So I want to be able to capture the codes for the TV, DVR, Sub Woofer and Surround system, as does the Harmony and then use that to control the TVs.
At least, if I design it well, I can use a type of keypad that will make swapping it out easy.
Your workshop looks great sir, also your ideology about "learning how it works before playing it". Thank you sir
