Looks good but needs an alarm and it must stay on until it wakes you up and you must reset it and check if the intruder has gone please help to modify this thanks
You did an excellent job explaining how to make this circuit! Thank you for rotating the breadboard so I could see how the pins are placed. Also, you explained the pinouts of the components very well! Thank you!
If the people walk into the laser and it the alarm goes off, the people will know that there's a laser light security alarm system there so they will instantly back away and then they will try to run across it as fast as they can to make the buzzer goes off in as little time as possible. If the time the buzzer goes off is too short, it might not wake you up, you need a system where the buzzer goes off when someone walk into it and stay on forever until you turn it off.
brother can you share the circuit diagram it would help me in my project rn i know i am a bit late but if u made it once i guess u can make it again(im in sooo much in the need of it)
Hey Can you please help me out I have done with this circuit but it is not working When the light is on then also it starts lighting and when there is dark then also it remains lighted
thankyou so much bro you are really a great while I saw many videos but no one define all the things they just put a song but from your video I get a great knowledge
When the laser light falls on the LDR, the circuit still remains closed and the buzzer/LED still produces a sound/light. Is it something wrong with my LDR or do I need to somehow increase my LDR's sensitivity?
Hey! Just double check if you've connected everything correctly as in the video. If it still doesn't work maybe this video of mine might help you 👉ruclips.net/video/ZIwBVln4cgQ/видео.html I hope this was helpful :)
Iam so Tankfull to you Bro Because How many videos if I see also my circuit got failed but your video was very helpful Tank you very much 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Can someone please explain how the ldr is made to work in the opposite way it is supposed to? Like what feature of this circuit makes it work as a darkness detector
Could you please provide with the circuit diagram or perhaps make one? It would be really helpful. ps. - also thanks for providing with the video. It has been of great help.
Hi. Can you please help me with the circuit? I have connected the whole thing properly but it isn't responding as it should (the circuit is not light dependent). Could you please help me out as soon as possible?
Hi. Make sure you keep you circuit in a dark place and focus the laser light on the LDR. Because sometimes since there's plenty of light in the room the LDR may respond to that light and not to the laser light. (So make sure the only light falling on the LDR is that of the laser)
Hi sir. What an amazing project♥️♥️. I'm going to make it in my school. I have a doubt that is it specific that we have to place the components in a particular block of breadboard. Plz tell
I am so grateful that this guy speaks English. there are SO SO MANY people who speak Hindi or German so thank goodness for this guy.
Indian is not a language
@@skyscapedrones2485 but don't you get it???
Thank you so much!!!!!!!!!You practically saved my physics project!!! God bless you
You're welcome! 😊
Thank you bro.. successfully completed our electronics project bcz of u...☺️
Thank you so much! I have a university practical in this exact topic later today and I did not understand what the brief meant fully until now!
OH MY GOD!!!!
THANK YOU SOOOOO MUCH
You saved my physics project
I was sooo happy when it actually worked..
Hey you're welcome! 😊
it is working... Thanks brother for uploading this video it gave me an good place in science galaxy expo... Iam so thankful to you😀😀😇😇
You're welcome! :)
im literally making this for my project oh my god thank you so much !!
We atlast completed our project with ur help
thank u!😀😀
+Indrayudh Das You're welcome!! 😊

Circuit diagram pls .. upload soon.... I am using this for my project

That's why Arduino exists.
Led is glowing but the buzzer is not making sound can you please help and reply
My alarm is taking a pause after i interrupt the lazer what should i do???
I prepared the circuit diagram and project report with this prototype by myself and got highest marks. 😃
Can you please share the circuit diagram? It would be of great help. :)
brother can you share the circuit diagram it would help me in my project rn
i know i am a bit late but if u made it once i guess u can make it again(im in sooo much in the need of it)
Very very #good..
And very #easy..
And work for my science exibition...
And I GOT second prize...
🙂🙂😊😊🖒🖒👏👏👌
bundle of thanks. It really works
can i use 2.2k ohm resistor????
pls anser fast
No. Only use 100k ohm resistor or else it will not work...
ok thank u so much this was very helpful
May I ask a question? Will there be any effect if we use a resistor that's less than 100k for its value?
It never works ☹️ plz help
The buzzer Is constantly making noise when there's light on ldr and when there's not what's wrong
Same problem
Hey
Can you please help me out
I have done with this circuit but it is not working
When the light is on then also it starts lighting and when there is dark then also it remains lighted
thankyou so much bro you are really a great while I saw many videos but no one define all the things they just put a song but from your video I get a great knowledge
Great job!
Perfect circuit that is gonna help me in my project
What type of laser is that - how strong is the light intensity? Can a cheap laser pointer work too
Brother my 12v buzzer is not working with this. Can you help me with some suggestion pls.
& What is yours battery's volt?
Hi. I have used 9v battery and my buzzer supports 3-24v DC. Use a 9v battery and try again?
THANKS BRO
IT IS WORKING
AND I HAVE TO SHOW THIS PROJECT ON TOMORROW AND IT IS VERY URGENT
+krishna swaroop Srivastava You're welcome bro! Good luck! 👍
my buzzer keeps buzzing at a lower volume even though my laser is pointed at the ldr. what should i do???
Will it affect the sensitivity of the LDR if voltage is lesser than 9V?
I did same as u did in the video but when I'm obstructing the laser light nothing happens. what to do?plz reply
What if we want to triger buzzer as soon as the light obstructed and if it again fall on the LDR our buzzer is not turn off for a longer time.
Thank you sir.its really working👍
When the laser light falls on the LDR, the circuit still remains closed and the buzzer/LED still produces a sound/light. Is it something wrong with my LDR or do I need to somehow increase my LDR's sensitivity?
Same problem with me
Laser light use cheysa ldr ki but buzzer stop avatha ledhu why kocham answer chepara
Hey bro I'm getting the sound of buzzer but the light isn't working and also it is making sound in dark too
this project is great...it's working position.
+Abu Taleb Thanks!
Buzzer does go off on putting laser on ldr. What could be the reason?
Why the circuit off when laser light is provided
I did it😀😀. Thanks for your help. Amazing 🙏🙏
How did you do
My circuit didn't work please help me
Thank yuo
The cercut worked but the buzzer didnt work

can we use 2.2 k resistor
Sir plzz tell me can i use BC548
Does it include assembly
it is working perfectly
Bro when I aim the laser at the LDR, the buzzing just doesn't stop.
Should I use some special laser or shall I change the LDR?
Change the LDR and try! It should work...
Superb bro! Thanks for this video
Could you please provide with the circuit diagram or perhaps make one?
It would be really helpful.
