[@unclestupid9108]

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

[@johnkennedy7459]

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

[@hristosesteortodox1794]

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

[@shivanibais9097]

It works
Thank you

It's amazing.

[@venkatanarasaiah7070]

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

[@pavanclinton8092]

Nice

[@akramhussin8524]

Nice vedios

[@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

Which ohm resistor you are using

[@IRONMAKER1]

Amazing

[@ayubkhanayubkhan6081]

what have u used to attach batt connector

[@mr.patil001]

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

[@fashionhaat4199]

Plz iska ak circuit diagram bna skte hai aap

[@KaushikMoumita]

Circuit diagram khotoy? Transistor number or Resistance number ki acha

[@faridi-bin-Zouq]

check description "KHOTOY"

[@thisalalochana5771]

awsome

[@angellacharles9890]

Can we off the alarm from outside without touching the laser

[@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

[@luisfigo3420]

Can the laser security alarm use dc 12V?

[@sunkkyMadeit]

Link to circuit diagram has expired…doesn’t show anything

[@tejasjather8814]

It works
