For outdoor lamp. Is this good for light lamp self and lighning ? If no do you have any solution. This is why the question because I will make best for any condition.
@tapendra mandal can you please give me the working in written just the hint like where we have to connect the collector pin , pins of resistors and terminals of battery....i just need urgent help for my project....please please just give me the clues at least....you can only help me out as i understood your video because you made a neat circuit I will be really grateful to you if you help me out......
your project is the best among all the projects i have seen on youtube but could u please give me the steps in detail as i have to wite them for my physics school project plsss
Hello Tapendr, i'm impressed with your projects or i can say you inspired me a lot but can you tell which software you have used in this video for breadboard circuiting?
He uses the opamp as a simple comparator in open loop configuration. So, when the non-inverting input of the Opamp is slightly higher than the reference voltage at the inverting input, the output will go high driving the led and the buzzer. For the non-inverting input to be higher than the ref. input it means that the LDR resistance has gone higher and that means its darker. So when its getting dark (adjustable by the little trim pot) the output goes high and lights up the led. Only drawback here: the Opamps output can max. drive about 20 mA - so just enough for the little led. If you need more current, just put a transistors base at the output of the opamp and use it as an amplifier or better as a switch here in common emitter config that means put the emitter to ground and the load (led, buzzer) between collector and Vcc.
@@kyordannydelvalle523 What is the part you dont understand? I think i was quite clear, pls. read the datasheet of the Opamp to understand who it works. Come back if you still have questions. I cant find my old answer in this conversation and dont know exactly what i wrote...

Bahut badiya project sir
Sir ye software ka kya name he

Still favourite in 2018. Thanks
Thank you so much. After 10 attempts, I finally made it right. Thanks.
Bro can you explain the problem you faced
Can u please tell me which software You'r using .....????
i start falling in love with electronics.....wow
+Thabo Sithole wow.. That's a good news
can you give me the link of the theoretical concept of this project. for oral defense . Thanks
Sir ur using which software in initial work
I am so going to make this. Thanks dude.
+Elexie Munyeneh good luck buddy

What is that blue colour small thing please say me the name of the thing please reply me I m not getting that thing
Hello Tapendr,
i'm impressed with your projects or i can say you inspired me a lot but can you tell which software you have used in this video for breadboard circuiting?
+Mr. Kashyap Amesara thank you..I used fritzing software.
Could you please provide the working principle of this project?
Sir, can u explain how the circuit works?
Hi Bro, the size of ldr?
suppose i am taken 5mm Ldr in this above project(i.e.dark sensor using ldr). so couldn't work why?
You didn't mention the 10K variable resistor in the materials in the description.Please add it.Thanks a lot! Hope this works!
He still didn't add and that's why I ordered incorrectly.
Can you make it without breadboard?
HELLO LIKE THE PROGRAM THAT USES TO SIMULATE THE CIRCUITS
Thank you... it's fritzing
ok fine thanks
Finally working 😮💨
Can you please explain the technical working of the circuit?

which software ur using... plss tell
Kaushik DIY's its called proteus 8
i did same work like you did in video but dont know why led and buzzer is working when light is open or not.
+Muhammad Shoaib tune the sensitivity via variable resistor.
hi..which engineering u did ..pls explain.. i alsdo want to do
electronics engineering
Tapendra Mandal e&c???
+Netra Patil yes
Hello, may I ask what the use of the buzzer is
Buzzer is for sound notifications..
please inform me in what value we put the variable resister???????
+Zyd hussain 10k variable resistor
what applications use it ?
You can make an automatic lighting system for your home...its will automatically turn on lights in night and off while day time
can you give me the link of the project details?

:) Tapendra Mandal Thank you so much
can i use ic 555
+Datu saud you can use 555 timer ic,but your whole circuit will be changed..
please i need that software.. can you tell me.. please
