Friends, there is a little problem in the circuit diagram that I have given here. Because of which it is not working for many. So message me on Instagram if you want to get the working diagram. Then please message me in Instagram I will give you the working diagram😊👇👇 instagram.com/skr_eletronics_lab/
Bhayea battery lag ne ke baad bajta hi ja raha h. Lesser light LDR par ja raha h tb bhi nhi band ho raha h. Plese advise me. It's important bcoz on 28th my science exhibition is held on. Pls help me.
can you please tell me the science behind the sound of the alarm, when we put our finger in between the ray of light at that time why does the alarm starts ringing ,i want to know thid because i have to explain it in the school
Bro u give us differnt material in discription he gave LDR sensoe and in video LLR sensor and in video 10k resistor and in discription 1k resistor Which material is right
Bro yr.. It's working in opposite way .. When I put the light in ldr the buzzer starts noise and when I keep LDR from light the buzzer stops ...Could you please say why is this happening.. It's urgent yrr🙏🙏
Sir ji mein security alram banaya tab usme Jo ldr per raser light Marne per Bo sound band nhi ho rha aa sound tej ho rha hai sir please Batao Kya karu please
Nice hai but jo sub ke ghar pe tv chalta hai jo seterbox hota hai usme ka jo sare masin kit hote hai usse ek science project video banakar daliye plz mere paas 2 seterbox hai plz kuchh bataiye plz🙏🏻
The schematic diagram is different to original circuit, -ve pin of buzzer connected to collector of transistor in original circuit, buzzer +ve is vcc with 10k, emitter is -ve while in schematic emitter not connected to-ve.
Isme Ghar ke bhi members jayenge fir bhi to alarm bajne hi lagega to kaise hm pata karenge ki kon Ghar me ja raha h kon nhi Bahar ke members ko kaise pahchan payenge

Wow wow 😮❤❤👍🏻👍🏻👍🏻👍🏻
nice project
Glad you like it!
Isme bada lezer nahi use kar sakte hai kya
Yes bro kr sakte hai 😊👍
But kaise please batao na
Is lazer connected to circuit is compulsary or we can use separate one
U can use separate one
Nice project brothers
Is there any other way to connect these all things exept soldring
Mein is ghar ki jaga or kay istamal kar sakta hu please response 🥺 it's working bro thanks
Ap is ghr ke jagah kuch v laga sakte ho
