8 years ago and still making a difference for us beginners! - Thank you

[@rajaravivarmar]

Man, you are a saviour. This video helped me to figure out the pins of a generic IR receiver. Thanks a lot. Please continue to educate us.

[@lalu225]

These tutorials are very useful for beginners like me. I like how you follow schematics and install the components accordingly. Plus the analysis that you do after. One recommendation from me is to maybe use more space on the breadbord and make connections with jumper wires if you think that might make it easier for people to follow

[@sohamadak8195]

thank you for this video ...it really helped in my college project....

[@rcghana3661]

i been watching ur new videos and Elonics man what an imporvement in every single aspect compared to these old one...greak work brother..keep it up

[@georgechingore1369]

You have no idea how the capacitor part solved my problem. Thank you so much 👍👍👍

[@shvideo1]

Excellent and simple educational circuit. Very well explained. Enjoyed it very much. Thank you.

[@erfinderwerkstatt]

Thank you for this video & circuit! Most IR test circuits I've seen used a transistor to invert the signal. This works quite well with the TL1838 which I can get for for 6 cent at Ali Express:-) I want to build simple IR controlled LED with kids at a local school, and this is a simple basis. I've dropped the resistors and use a 3v coin cell (I know, bad practice, but the internal resistance is enough to prevent high currents for the LED and IR-rx). The battery is held in place in-between Popsicle-sticks with rubber bands, the LED and tl1838 just plug in there too, and the LED cathode and rX signal pin touch ontop of the stick.

[@elonics]

I'm happy to hear that! The arrangement of components is great!.

[@johndavid8949]

[@howahwhat]

Thanks so much for this video. I was looking to learn how and what to use to design a simple remote switch. I am just learning. and will be doing my own experiment. To start off some simple trial at my own time. Its just for creating some useful function from remote. At least now i have some idea and Thanks for explaining it so very clearly of the purposes of each components and its alternatives.. Thanks.

[@elonics]

You are welcome. I'm glad to hear that.

[@ritashrana3477]

awesome video and i want to know how to connect tsop with 12 volt supply as i am try to connect a led strip to it will be more helpful if you can provide a circuit diagrm of it

[@frncsldd8236]

I hope you reply i really need an answer. May I ask what is alternative use of TSOP 1738? Because I only have VS838. Are IR receiver are all the same?

[@eswarp477]

can you tell me the working that mean principle how it worjs

[@suvankarchakraborty8902]

It's working

[@kaustubhshastri3780]

[@sheikhmoin7292]

hi man.. I need som help.. I hav a phone which acts as remote... so I wanted to kno how to make a switching circuit.. so dat I can use it to control fan in my home.. thnx in advance

[@zeondias3524]

I m nt getting IC tsop 1738

[@srihari1992]

Sir I will used phone instead of remote it possible, how much cost ic ,where it is available.

[@virajsadhale2788]

Hey, the datasheet link isn't opening at the first place.

[@blankooy2485]

TSOP1738 is getting burn every time I connect it, how to prevent this?

[@rajivnayansingh7469]

thanks

[@hasibabdullah7508]

can I use sm0038 instead of tsop 1738??

[@rohitramdas7060]

Sir please make a video of how to make a ir remote

[@alvinoorhossain8459]

can i use your circuit to make an on and off for the led other than the switching with the remote, if i have a phone connecting with ir transmitter of from the headphone plug can i control this?

[@elonics]

+Alvi Noor Hossain Yes. But to toggle the LED you need to add a flip-flop to the output and connect LED to the flip-flop.

[@89elmonster]

so let's say I want to replace my rooms light switch with a wireless switch, what are some things that I should know?

[@revoxsvko]

Jarmahent arduino

[@gurmindersingh7602]

can you plz tell that does remote control emits 38khz frequency? will this circuit work with a car stereo remote controller or cable remote control. thanks

[@elonics]

Most of TV remotes work on 38khz. Give the car stereo remote a try.

[@stevenlee1726]

Hi sir, For example: When pause button is press, i want to do one thing. When stop button is press, i want to do another. Is it possible to do that? How the receiver circuit detect different kind of button is pressed? Thanks urgent. I think adding just microcontroller code doesnt worked because no matter which button you pressed, tsop1738 output is only high or low. So, anyone can solve? Welcome to reply

[@elonics]

TSOP1738 gives PWM output with data corresponding to the button you've pressed. You should use a micro-controller to decode that.

[@prithhviraajchattopadhyay7698]

This should work properly if we use a 9v battery and a 220ohm resister instead of a 470ohm resister, should it not? This my question Actually I was trying this project from instructibles but well, there seem to be some problems.... Could you please clarify my doubt?

[@elonics]

Optimum supply voltage is between (5-6)v. You can use LM7805 to reduce voltage to 5v. TSOP1738 can output maximum current of 5mA. So it should be sufficient to drive a normal LED. In case if you want to drive a brighter LED or require more output current, you need to use a transistor.

[@kennyball3956]

hey me again lol...whats the difference between the tsop1738 and the vishay dip 3 as im trying to buy some for this circuit...thx

[@elonics]

DIP means "Dual In-line Package" and DIP3 means "Dual In-line Package with 3 output pins". It just specifies the component's package type.

[@serginx]

Can I send audio for this receiver ?

[@dhimanshome5821]

Sir can I use it to make a obstacle detector by putting an ir led?

[@elonics]

No, use a circuit like this: goo.gl/images/44wFBx

[@kathyl5664]

How far away can you be away from the IR receiver with the remote to activate it?

[@elonics]

It worked for distances more than 10 meters indoors.

[@RossiIcq]

Why the LED is not connected with GND

[@yashkhedkar1823]

I was trying to make a boat out of my old rc helicopter so it had this ir and wanted it to control 2 motors can you help pls

[@elonics]

Increase the capacitor value at the output and give it as input to the rc helicopter's motor driver.

[@ZunnoorainMasroor]

its not working, led is constantly on, remote isnt making any change, LED is already on without remote or any other IR source

[@ericfernandes3966]

Will it work on.3.7-4.2 v? I have my drone supply on a 3.7 battery ,and wanted to add this also

[@MrGenia1991]

not a good idea. try to use similar rc modules but not IR

[@MrGenia1991]

did u solve your problem?

[@shiro5410]

can I use tsop 1736?

[@bhasuruarchana3916]

Can we use any remote

[@InfiniteGround]

What cool

[@sanskarlamsal]

Does BC1838 works?

[@raghu1332]

bro what i want to study to make like this experiments i mean wht course i want to take nxt .plz reply me .i am studying inter 2yr now so.

[@elonics]

You can start from making basic electronics projects on breadboard and then move to PCB's. There are plenty of KZbin videos. I would suggest you to do these along with your education.

[@dishantkashyaprock]

you can rather test your remote by pressing the buttons of remote in front of the camera, if the light glows (which can be only visible in mobile screen) then your remote is working fine.

[@luisleonardojuarez7389]

I have question. Can We use anything remote control to prove the circuit or there is one specific to use?

[@elonics]

You can use any remote that works on 38khz.

[@irshaadtiger]

how to control irDA sensor

[@kennyball3956]

cant get it to work.....im using the "keyes k845754" ir reciever....it has some surface mounted components and 1 is an LED is this my problem ??

[@elonics]

Its pin-outs are different. Go through this: tinkbox.ph/sites/tinkbox.ph/files/downloads/Keyes%20-%20Infrared%20Receiver%20Module%20.pdf

[@kennyball3956]

thx for the responce....i found this but its a different module...mine is the red 1 that came with my R PI starter kit....this does get the led to light on the module but i cant get the led to come on with the remote....thx again

[@elonics]

I looked at it. The TSOP1738 outputs the demodulated signal directly without any conversion to serial data. So the output is continuous. But in case of keyes k845754, AFAIK the output is in the form of "serial communication". It just sends the data in a split second and stops. So, the LED doesn't appear to be glowing.

[@kennyball3956]

Elonics - Electronics Projects on Breadboard thx mate

[@seethukrish]

Can I use this circuit to build a DSLR remote receiver?

[@elonics]

Yes

[@prashantmadan2106]

can i use regular infrared led instead of the remote?

[@elonics]

No. If you use IR LED, the range will be in the order of millimeters.

[@user-bd2cl9ig3w]

❤❤

[@mamawnako]

Are there different kinds of IR receiver? I saw some with a receiver that just looks like an LED and other like this that is an IC, do they work just the same?

[@elonics]

The one which looks like an LED doesn't have a demodulator circuit which makes it more prone to background Infra-Red noise and so the range is less. The one which looks like an IC has internal circuitry to respond only to Infra-Red waves with 38kHz frequency (For TSOP1738). So it responds only to IR remotes and has greater range.

[@mamawnako]

Thanks

[@mamawnako]

One more question. :D Is the 38kHz frequency the common frequency for IR transmitters? I'll be trying to make a circuit that uses IR LED (don't know its freq.) as transmitter for an object counter, would the TSOP1738 work just fine?

[@elonics]

A simple IR LED doesn't emit modulated waves. It emits plain InfraRed rays. You need to use a 555 timer or micro-controller to modulate the emitted light at 38kHz. This circuit will do that: goo.gl/images/VbXBu5

[@mamawnako]

goo.gl/W4MFnc This is what I'll try to do. Should've posted it earlier, sorry. Will the TSOP be good for this?

[@sidharthpande7493]

good video bt led is on always & when i check remote its power low nd high

[@roboticsridoy]

I want to 4 output this system. it is possible ??? please help me !!!

[@elonics]

If you mean toggling, use a 4017 IC

[@syednomanghazali2684]

what to do with the other two ends of jumper wire.Please any one tell me

[@elonics]

Connect them to 5V Power Supply

[@manithapasandul473]

can I use a 50 micro farad capacitor

[@elonics]

+Manitha Pasandul Yes, You can. The capacitor is only to smoothen the pulsing of LED.

[@electronicprojectspune3523]

i used same capacitor but still not smooth operation

[@danhle2446]

Rất hay

[@elonics]

cảm ơn bạn

[@virajsadhale2788]

Capacitor does the work of storing energy right....so how is that storing of energy working over here?

[@elonics]

TSOP1738 outputs discontinuous output signal. By adding a capacitor, we store a bit of energy when there's a bit of signal and provide it to the LED when the signal drops.

[@yashkhedkar1823]

Can you tell me how can I control a dc motor with this ir remote ????????

[@elonics]

+yash khedkar You have to add a transistor or a motor driver to the output and then connect a motor.

[@SouravDas-ho1uu]

I want to use another IC..I use another IC???

[@Bachulia]

hi man is ok nice, so how mach of distans I can glow it?

[@elonics]

10 metres

[@Bachulia]

Elonics - Electronics Projects on Breadboard thanks man

[@ashwinshetty1961]

It seems that you are obsessed with blue LEDs Same here😂

[@bbvlogsandgaming1602]

😍

[@dazuwild4565]

hey bro how can i make these led on and off help me!!!!

[@elonics]

Wait for two days, I'll make a video on that.

[@dazuwild4565]

ok thanks

[@swishboy]

Can I use tsop2236 in this testing circuit?

[@elonics]

TSOP2236 works with a remote of 36khz frequency (The last two digits of the part number corresponds to this). But most of the remote controllers operate at 38khz. So most probably it doesn't work.

[@gustakyadav586]

Sir Capicitor ki voltage ka hai

[@alisaeed8043]

Can we use a battery of 9v?

[@elonics]

No

[@nolwexd5272]

Can it be conected with a phone charger?

[@elonics]

Yes, it will work

[@BANGS-vr9wf]

hello sir can we use a 9 volts power supply ??

[@elonics]

No. Voltage should be between (5-6) Volts. You can use LM7805 voltage regulator to reduce the voltage to 5V.

[@BANGS-vr9wf]

ok sir thank you

[@anwerbasha725]

Is it important to use a capacitor

[@elonics]

No, it isn't

[@irshaadtiger]

bhai irDA Ko kaise control karain

[@jatinchauhan9111]

can we add a buzzer in it

[@elonics]

Yes. But TSOP1738's output is rated at 5mA. So if the buzzer consumes more than that, you should use a transistor at the output.

[@alistairdsouza983]

This circuit is not working

[@sangramnevsea2854]

hey can I fit a motor to it

[@elonics]

Not without using a transistor

[@hinaparveez7515]

can i use any tv remote

[@elonics]

Any remote that operates on 38khz frequency. Give it a try, most probably it'll work.

[@ednaldopereira7968]

show👍

[@nikhilbenarji9028]

can I know with which remote it works

[@elonics]

It should work with most of the remotes (They operate at 38 Khz) I tested with sony and LG remotes.

[@nikhilbenarji9028]

+Elonics thank you

[@nikhilbenarji9028]

+Nikhil 6213 can any one send PDF or PPT for remote tester

[@brooksrobinson7617]

what power source where you using?

[@elonics]

4 AA Batteries in series. It gives around 6v.

[@brooksrobinson7617]

thanks

[@bavitamittal9745]

i am not able to understand where the capasitor has to be

[@elonics]

+bavita mittal Between output terminal of TSOP 1738 and Positive (Vcc). Refer the diagram in this video.

[@rohitmaity2529]

can I use it to built remote control car circuit ?

[@elonics]

Control only in one direction is possible. Because this circuit can just be used to turn a motor on or off.

[@rohitmaity2529]

so then plz show a circuit that can run a rc car

[@elonics]

I'll make a video on that soon.

[@sohamadak8195]

sir ,can i use 9v battery instead of 6v??

[@elonics]

No, you shouldn't. In case if you want to operate the circuit on 9v battery, use a LM7805 voltage regulator.

[@sohamadak8195]

OK thank you sir

[@sohamshinde4818]

My led is flikering without any remote buttons pressed...pls tell sir why?

[@ramyachippada]

Can we use 9v battery

[@elonics]

No, 6V is the maximum

[@prithhviraajchattopadhyay7698]

and does a transistor really serve no purpose?

[@_greysama_]

Can i use tsop1838?

[@elonics]

Yes, you can. It is an improved version of tsop1738

[@ThisIsMySig]

Um, what are you saying?

[@stanleyvictor2998]

what if the led glows when the supply is given???

[@elonics]

The LED flickers for fraction of a second and turns off when the supply is given. This is normal.

[@stanleyvictor2998]

Elonics - Electronics Projects on Breadboard its not even flickering, it glows when the supply is given and it is not turning off back.

[@elonics]

The cathode of the LED goes to TSOP1738's output. If the connections are fine, check if the LED changes its state when a button on IR remote is pressed.

[@stanleyvictor2998]

Elonics - Electronics Projects on Breadboard the connections are fine but the led is not showing any changes. is there any configuration for the remote

[@stanleyvictor2998]

Elonics - Electronics Projects on Breadboard sorry brother will check the connection
