How to make a "Laser Security Alarm System" at Home on a Breadboard [HD]

My alarm is taking a pause after i interrupt the lazer what should i do???

Does it include assembly

May I ask a question? Will there be any effect if we use a resistor that's less than 100k for its value?

Thank yuo
The cercut worked but the buzzer didnt work
Can explain the matter

I realy fear with that

why you choose 100k resistor ?

Can you explain the circuits working that is how the current flows

Could you please provide circuit diagram...

product list plz sir

Laser light use cheysa ldr ki but buzzer stop avatha ledhu why kocham answer chepara

Code kider h

Resistor is of 1 watt?

Where can I find circuit diagram for this project ?

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

Brother my 12v buzzer is not working with this. Can you help me with some suggestion pls.
& What is yours battery's volt?

Thank you sir.its really working👍

The buzzer Is constantly making noise when there's light on ldr and when there's not what's wrong

Thank you bro.. successfully completed our electronics project bcz of u...☺️

Can we use 330 resistor instead of 100k ohm,plz tell as early as possible,I have to submit it tomorrow morning

Why bro

It is working opposite way

it is fake

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 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Circuit diagram?

Can you help me with your email address please I need to do a project and I'll need your knowledge

Buzzer does go off on putting laser on ldr. What could be the reason?

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!

Sir kya iski circuit diagram mil skti hai

Sir it is not working please help me

Can we use any other resistor for 100 k

I did it😀😀. Thanks for your help. Amazing 🙏🙏

Sir plzz tell me can i use BC548

Thankyou very much sir
..

With out resistors

It's work so thank you

Not working

Thank you for this idea hear is theaf comes thank you

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

circuit diagram?

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.

sir it will work? when we use 2N7000 transister and 6.8k resister instead of BC547 Transister and 100k ohm resister

Is usage of 5w diode laser compulsory ?

HELP PLEASE!🙏
If I want to add a switch to the circuit, where should I put it in the breadboard?

How much is the buzzer voltage??

Ty for the 5 marks :)

Can u plz upload ... circuit diagram and working of these

I made this. But it was not working. I don't why. I did exactly what you did. But it's not working 🙁

Thanks. Need circuit connection hand sketch

Why did you use ldr sir?

I prepared but my project is not working
