Very lucid explanation. Even though I sort of knew how this circuit worked, your explanation clarified it completely. You have a great talent at communicating ideas. Great job!
One of the first video in complete junk on this topic on RUclips which actually showed the correct circuit otherwise all videos show photodiode working in forward biased state. My friend I assure that I will try to have you as many subscribers and likes which you deserve and which I can!
My review of this is from the viewpoint of a beginning hobbyist. My review is generally positive. On the plus side, you discuss how it works and how to put it together. This is a big plus. On the minus side, you do not show a schematic, which is mitigated by the link to it. Also, you did not go into detail about each pin of the LM358, although this could be mitigated by a reference to a video covering the subject. You get substantial extra credit for that link to the troubleshooting video. This is Gold to a beginner. I’m subscribing because I see tons of potential in you. You do not make annoying presentation mistakes like using messy low contrast schematics on ruled paper, the type of mistake that gives the audience eye strain. Your script is well crafted and probably rehearsed. I am expecting great things of you.
One more caveat: References are good, but do not over do them as DC Comics did. They had successful series in the 60s called Crisis on Earth One, Earth Two, etc. Afterward, each issue of DC had increasingly many Editors Notes until the whole thing became a monstrous unreadable mess in the 80s. DC had to redo everything because no one could read through their tangle. References are good, but don’t be tedious.
Great video, mate. This is the setup I had in my head but wasn't sure how it'd work, and you've gone through it in a clear and concise manner. We even have two channels on the op amp, so we can build a dual sensor unit in this manner that doesn't require an Arduino or what not to act at the comparitor or voltage reference-measurement. Love it.
Bonsoir, un grand merci à vous, l'animation est de grande qualité, l'explication en anglais mais on comprend quand même en visuel même pour ceux qui ne maitrise pas la l'anglais, et ça c'est super.
Well done video. I especially like the close-up photography so actual pin locations can be followed. Furthermore, the additional video editing with directional arrows, shading, and highlighting etcetera make following the concepts much smoother. Thank you!
The detailed explanation is awesome. The amount of detail to include troubleshooting in the description is great, thank you so much for putting this together.
The music was really nice. Thanks for explaining this. I have troublie understanding op-amps and I really need to improve my knowledge about it. great video
If you are all are wondering why the LED is continuously on, it is because there is no barrier between the light detector (white) and IR LED (blue), so it will always pick up light... Some masking tape between the two - without covering the domes - should help (although I have not tested this circuit myself).
Thanks for posting this tutorial. This circuit worked for me. Although my IR receiver is black and my IR emitter is clear, which is flipped from what is shown in the tutorial. I had to adjust the 10kohm resistor to change the sensitivity for my application.
Great video, very well presented. For some reason mine was on and turning off with proximity. After much consternation I swapped the wiper (center tap) of the pot and put it on #3 and moved the receiver wire to #2 and lo and behold it worked. Not sure if the schematic is wrong, my LM358 is backwards or something else. Note, if I approach the circuit from one side it has a range of approx. 3 feet.
Thanks for the simple, accurate information regarding how these things work. But a warning! Make sure your breadboard is functioning correctly. I had one that was shorting out the pin connections. Yikes! Cheap ass board caused lots of hair loss. lol
It worked on my first attempt. I used 5V mobile charger supply to power it. Suggestion- 270R should have higher wattage, gets hot on 12V & please use different colored wire for +ve & GND.. Thanks.
Your circuit has a humongous flaw that will render this useless. You've labelled your photodiode as a transmitter, And you've labelled your infrared diode as a reciever. The entire circuit and theory behind this is perfect, but you have to swap these two. Infrared diode(transparent) positive pin to VCC, negative to R1 resistor which is then grounded. Photodiode(black) positive pin connected to pin3 of OpAmp as well as a resistor which is then grounded. Negative pin of photodiode to positive.
I see that you noted this, "Note: For supply voltage of 9V or more, use 1K resistor for LED and 470R for InfraRed(IR) LED" Would I still need a 1K resistor for the LED if I was actually going to use that connection to light a LED stip up to 10 feet long? I know a single LED couldn't handle more than 5volts, but a strip should be able to handed the 12volts
Bro it's really clear video with very nice explaination, I like your video sooo much. Your explanation of working of this project is sooo impressive. Please do more vudeo with explanations how the components are works. Please make an video how to controll water faucet using solenoid valve using LDR and Light + even using IR tx and rx with explanation.
Sir, does the infrared source emit the infrared rays uniformly in all direction? If it so doesn't the photo diode should always be sensing it as the source is very close to the photo diode in this model. 4:19 doesn't the statement should be 'voltage of inverting input is lesser than that of non inverting input'
Very descriptive video! Thank you! But, is there a way to make the LED slowly brighten when movement is detected and then slowly turn off as movement stops and then be able to adjust the brighten/fade?
Im pretty sure the the black diode is the reciever, not the emitter, and is that an inductor you used to bring the black diode to ground? Im pretty sure you said its a resistor, but it looks just like an inductor.
friend:don't watch that video it's and Indian video Me: and it's way better than our teacher most simplified video i love Indians they are kind and quite smart and this one ngl the english accent is relaxing and beautiful
good demonstration...But how can i increase the range of IR sensor?/.....In my case LED glows when we close any obstacle to the sensor So the range is very low....
if you face any difficulties in making the circuit work as expected, watch this: ruclips.net/video/036kskbFf40/видео.html
Could you please send me the video or circuit of ir sensor and counter
I have a problem. Do I need an infrared diode and a photodiode? or
An infrared diode and a phototransistor?
Great video, Logically explained and intuitive, thankyou, subbed.

There is nothing more beautiful in this world than that smoke animation that plays when you add another component to the breadboard.
Very lucid explanation. Even though I sort of knew how this circuit worked, your explanation clarified it completely. You have a great talent at communicating ideas. Great job!
Please circuit send Karo na 🙏
Man, this idea will literally save my project! Love you
I wish I had an electronics teacher like you! Your content is very clear and understandable! Wish you success!

Thank you for the comprehensive feedback! I liked the idea of having reference videos. Will do that for the upcoming videos.

How?
@@big_o1952 It's complicated, but basically I used it for a very important homework
Neat explanation. Thank you for making me understand how it works!
Best explanation i have ever experienced
Finally it worked !!!! Tnx Elonics for my College project
Bro circuit diagram plzzz
very helpful for me, a beginner studying basic electronics ...
and then bro doing an electro project, gbu
Nice animated tutorial for beginners. Thanks
You having a relaxing voice.
it is out standing,,,,,,,,,,,,,and nicely explained....
Yep it is dated, but still then it's fun!
Nice work
There are lot of vedios to make circuit,but when come for explaining,nobody comes forward! Thanks
Awesome ! , no BS clear explanations , Thank you
You're welcome!
Great project and video! PLEASE make the schematic for this circuit available. Thank you kindly
The link is in the description, pay attention!
Cool project and great explanation!

pls make a op-amp series :) your 555 series is great
Looks like you have mixed infrared led with infrared photodiode, but although a good project
That was a brilliant video with very clear explanations. Thankyou.
You're welcome!
Very good explanation. Thank you!!
Very well explained. But i have little confusion the white one should be ir led and black one is ir receiver. Please clear my doubr. Thanks
Sir ur presentation and explanation is very good👌👌👏
please do show the circuit diagram once for easy understanding
The link is in the description, pay attention!
I see that you noted this, "Note: For supply voltage of 9V or more, use 1K resistor for LED and 470R for InfraRed(IR) LED" Would I still need a 1K resistor for the LED if I was actually going to use that connection to light a LED stip up to 10 feet long? I know a single LED couldn't handle more than 5volts, but a strip should be able to handed the 12volts
LED strips usually come with resistors soldered for every 3 LEDs or so. You may check the spec and if it is rated 12V, you can skip using the resistor
Excellent project
Very nice! You explained the circuit perfectly!
Subscribed!
Very nice explanation.
Nice video quality,great explanation with animation...simple English....thanks
this my fav channel ❤❤❤
thanks for explaination, just want to ask which is the IR radiation emiting diode the black or the transparent one ?

Thanks a lot bro. I did it for my project and it's coooooool
Thank you. Great video. Keep up the great work!
You're welcome. Sure!
Hello, i just have a question. What exactly are the wires used in the video, and what are their names?
Thank you Elonics!
Clearly Explained & it worked well too , Thank You brother!!!
No words .. just Awesome.

Good video.
I like this...
I have not LM538.
Can I use LM742????
Yes, you can use any type of operational amplifier. Just take care of the pin-outs
Thank You and God Bless You Sir

This how solar battery light work this is briliant.
How?
Thank you for the explanation
Which potentiometer should i buy to make it?
Saved my day thanks a lot
Thank you very much for your good video.
The LED stays on when I turn the potentiometer. Please help.
maybe check your connections:)
Here is the troubleshooting video:ruclips.net/video/036kskbFf40/видео.html
Great, it 's work.
Can it output to relay ?
Doing a great job buddy ✌️💚💚
AMAZING VIDEO GOOD WORK
Bro for this project shall we add buzzer
In circuit diagram resistor used are different ... So which should v use definitely ....
Please check the description
conceputual and simple explation .
thank u
thank you so much for this great explanation... i just want to ask how can i connect 12v relay for this project thanks?
I went to your site and raised resistor values because my power supply is 12 volts - even with bigger resistors I keep frying 358s…
Sir please explain why you have taken 270ohm only for the 2 resistances
this setup can be used for heart rate monitoring, right? the output being connected to any analogue pin of MCU.
PERFECTLY EXPLAINED.
Hello brother, where are you located in India? I want to get in touch with you for I don't know coding and I want to see how voltage change
