[@johnkennedy7459]

nice experiment.... useful.... hats off!!

[@unclestupid9108]

Thanks for your video.it's really works and I have made one.

[@user-eu3jz8kb4q]

Well done keep it up 😎😎😎😎👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍🏆🏆🏆🏆🏆🏆🏆🏆🏆🏆🏆🏆all the best for next video

[@hristosesteortodox1794]

Hi. Can i power the circuit with 5v from usb power bank?

[@nikhil.nikhil]

Gud job Bn gya bhai

[@shivanibais9097]

It works Thank you

[@jpscafe7648]

😀🗣Da hora meu! Muito bom, esquemático beleza👍👏🇧🇷 me inscrevi. Bonitas unhas😵💅

[@saumybhardwaj2910]

very nice project I try to do

[@sunkkyMadeit]

Hello please I need help with the soldering..I can’t get mine correct…the video doesn’t show the full soldering

[@venkatanarasaiah7070]

Bro can we use one resistor and one transistor is that not enough tell me

[@ItaloLima]

Good !!

[@prathameshraul6914]

Which ohm resistor you are using

[@omprakashprajapati8120]

ek sat 2 chij cala sakte Hai kya

[@ajjum6121]

[@pavanclinton8092]

Nice

[@pasha7984]

Very good

[@ayubkhanayubkhan6081]

what have u used to attach batt connector

[@arshadeqwal6056]

It's amazing.

[@akramhussin8524]

Nice vedios

[@naficeahmad]

Very nice project bro i like your videos.

[@Hobbynics]

Thanks.

[@sunkkyMadeit]

@@Hobbynics please I need help…it not working….I think my error is in the soldering….I’m using 547

[@luisfigo3420]

Can the laser security alarm use dc 12V?

[@fashionhaat4199]

Plz iska ak circuit diagram bna skte hai aap

[@keithwatkins1728]

Please can you show us how to make the buzzer to keep on buzzing so that it can wake us up and we can reset the alarm? At the moment we will not hear one quick beep and the intruder will wake us up. please can you make this modification thanks

[@mohamedasarudeen1855]

Super g

[@ayubkhanayubkhan6081]

'wat have u used to attach batt wire

[@angellacharles9890]

Can we off the alarm from outside without touching the laser

[@nikhil.nikhil]

Ldr konsa lena h bhai

[@Hobbynics]

+Nikhil Gupta you can use any LDR

[@nikhil.nikhil]

Technical Nisar ok

[@aartiboke2411]

Nikhil Gupta LDR kaha milta hai

[@thisalalochana5771]

awsome

[@rockyhandsome3182]

transistor bc 548 hai kya resistance ka number

[@IRONMAKER1]

Amazing

[@KaushikMoumita]

Circuit diagram khotoy? Transistor number or Resistance number ki acha

[@faridi-bin-Zouq]

check description "KHOTOY"

[@mr.patil001]

What is capasiti of resistare and transistor mail me

[@piyushnikam3892]

How much volt buzzer

[@adarshraj4495]

can u avail me ldr in my city darbhanga bihar

[@tanushreesagar2328]

It worked

[@mr.patil001]

What is the unit and capacity of resistance and ransistar Please send

[@rayyanfarooqui4822]

What is total to make a laser alarm

[@tejasjather8814]

It works

[@sktech7579]

I've made the same circuit but its not working properly when I throw laser light on it it does not stop buzzing... I've checked the circuit many times it's all according to your given diagram..

[@Hobbynics]

Check polarity of components and no. of transistor

[@sktech7579]

+Technical Nisar now ive used a resistor of 200ohm at the base of 548 its working great thanks

[@anshulthakur7502]

Sajjad Khan Fazli i used 200 ohm but its not

[@rohitjawale777]

Can I use bc 547 Transistor

[@sunkkyMadeit]

Hey did it work…I’m with it now but I don’t know if I got my soldering correctly it not working

[@Viral_.Shorts_1]

Light aane per buzzer on hota he off nahi hota he
