Why is this channel not getting 100 millions subscribers? This is good video, this is good information. It's lame how crappy videos get thousands of views in one day and million of subscribers, but the good ones are doomed in obscurity.

So concise, so comprehensive. Thank you. I've been looking for those tiny bits of precise info, which you can get by watching hours of tutorials here and there.

This video is awesome! I love it! You explained everything very clearly

Incredibly much of crucial info on onfrared control in such a short move. Excellent!

I was looking for 10 mins for a video, this explained it perfectly (Thanks !)

Nice explanation. Reminds me of morse code in parts.

that was freaking awesome the code part was like DNA sequences we had in school and college keep going man

Thanks!! You saved my life. I have a Science Project next week.. Thanks a lot :)

helps me a lot even in short presentation !! thanks !!

very neatly explained thanks man

this blew my mind. thanks!

It's very helpful, thank you!

that was really helpful... Thanks, man

Great video, question? I have several small 3.7 volt helicopters like the ones in this video, at the end, with no remotes that match them so that they work. Is it possible to alter the frequencs of the ones I have, to math the helicopters, so that they will work? Thanks, any help would be appreciated.

Best explanation

Nicely explained

Great tutorial thank you... John :)

hey Rick can you tell me if we put more ir bulbs to a remote control will it increase the range please reply....

Great video. What would happen if you added a few IR bulbs to a RC helicopter control? Would it gain range? Would it gain directional signal?

this is very helpful :)

So can I use a fiber optic wire to curve the ir and deliver the ir through a brick wall?

Wow thx I can now do a simple demo tomorrow at class

superb but were did purchase and it is used to high power current also

If I would remove the ir transmitter and ran a wire from those 2 pads and hooked the other end of the wire to the ir receiver would that work. Basically hard wiring it?

Sweet video

Very helpful :D

Thank you!

very usefull information

but how the television is made to pick up only 38khz infrared? and how can it interpret those signals to do something specific?

Hi, may I ask, how are IR remotes able to reach long distances? For example, my TSOP IR receiver receives my TV remote's signals from far away, even if I am pointing away from the signal. May I ask how is this possible? I am intending to create a button that sends out a signal like my TV remote's signal, but I don't know how to make my IR signal stronger..

very nice video! I have a couple questions, I hope someone will answer. 1- you said tipycally the IR freq of a tv is 38 khz. But since a sony remote control will not work with a toshiba tv, this means that some one uses 38, some 37, others 39 right? A universal remote control will work with each tv because is able to transmit in a wider IR frequency range?

Hi Rick hope you are well, I have just purchased a " Bigfoot toy " The remote control is missing! could I some how get another type of remote to work?... Many thanks... John :)

Question: from what you presented, is it possible to design an infared remote to change the channel, song, volume etc. that is playing ON your phone/tablet instead of using a Bluetooth remote/keyboard?

Hi, great video I am trying to reverse engineer a remote control for a helicopter toy like yours Can you give some information about how does it work or some sources ? Thanks

this is a good video, but I have a question. is there a database or repository of codes used, or remotes matched with codes? I am interested in this project because I lack a remote for a piece of equipment, and obtaining a rare one will cost a stupid amount of money right now. I'd like to see if its codes are already known such that I could simply use them with this project without the learning decoding step.

can u show how u make the remote controll of helicopter using ir sensor

Thank you for this video. I have a question though. For a school project I am trying to built a device which is located on the ceiling and could alert on whether an object (non moving) is within the radius of 1 meter in all directions. It should be very small and cheap (less than 5$) so any solutions like radar or laser scanning is out of the question, so I left with the ultrasonic and infrared possibilities, but due to budget and size limitations i need to use as few sensors as possible. I have tried to make some measurements with infrared transmitter and receiver in the same housing but so far Ive been able to detect only objects in the range of about 15 cm, and pretty much only if it is perpendicular to the sensor. I have used all kinds of IR emitters with different radiant intensity and with different current values but I could not significantly increase the range and the beam detection angle my question is how could I increase the range and angle? I check the IR detector with a normal TV remote control and i see that the range could reach up to 5 meters and the detection angle is very large. is the IR transmitter in the remote control is amplified? and if so, how? with optical lenses or with electronic components? sorry, it got a bit long Thank you :)

And how does the sensor work? In programming a query is only in one moment in time (extremely short). How can it scan at any moment in time for any duration? I'm a beginner engineer and I had that problem recently

Thank u very much..................

this is very helpful, thanks a lot. But I still have a question that if I have a general IR remote control that flashes an IR signal with 38khz, and had two devices that are designed to respond to 38khz, will they both work if I pushed a certain button ? and let's say that I didn't know that information, how will I know which one of the two devices is going to work ?

Fantastic explanation, have you considered teaching or lecturing?!

I KNEW IT. I EVEN FIGURE THIS OUT MYSELF. So some IR blasters have two IR lights. What the meaning of that?

Very interesting, I knew it used infrared light but wasn't sure how data was transmitted.. I suspected it would be like this, because it sounds just like "Li-fi" what some people predict will be the future of Wi-fi. What was really shocking is that the RC helicopter uses infrared, I thought it was some really low-power radio waves. Are all RC toys using infrared? How can the helicopter catch the light from a far??

This video is easy to understand Thx 🙏 I feel like my science project got way easier Also whoever disliked the video is a wuss

Thank you

could you do more of these videos inwhich you explain about remote contorl and sound system in tv? many thanks. i also subscribed your channel

I have a question. What if the LED works but when you press it, it won't change the channel? (sorry for my bad english)

thank you

Rick, just subscribed. Great work. You said, 38khz means it flashes 38,000 times per second. How is that possible? Have you seen a video that explains how a remote or circuit creates that specific energy? If so can you send me the link?

please give me the solution to control AC using raspberry pi and lircd lib, please give me any link or code to control my onida AC in detail

U blew my mind

Hi, can you elaborate on how to control the helicopter with the IR remote as I am exactly looking to do that. Thanks :)

I know this sounds stupid but does this relate to controllers for video games (ps3,xbox) as well?

Okay then, how would i make a system consists of a IR remote transimitter and a reciver which respond to it..

I've a remote control which IR led always stays on. When I press a button the receiver doesn't work. I've tried to clean up the button contacts, I've changed batteries, but nothing!

So why is it purple like a "black" light? Isn't that ultraviolet light?

yes for my science test

inverter?

nic bid

How can 1s and 0s change my channel? Still don't get this stuff

When you realized this video is recorded vertically

this protocol is called rc5

It's weird to see a remote controlled vehicle based on infrared rather than on radio 😳

Does any smartphone has tis tis IR based remote control???

fake vedio

thank you
