⚠Notice : If you are using BC547 instead of 2n3904 (I made the video with 2N3904),you need flip the BC547 (face down) , since BC547 pins out are different from 2N3904 , BC547 is CBE(123) , 2N3904 is EBC(123)😊
Its not working for me my led working every time 😔😔
Can I use ST8550D transistor?
T
@@_Tane_media ya that's what
😂
its very informative but plz do tell in more details. i love to see this. stay blessed.
Forget the circuit m using nail cutter to cut the pins ,thanks 🤩😂
I do that too, glad i'm not alone.
Yo bro me also
😜
Im also
I did it but my nail cutter broke.sad life🥲
Working very perfectly I have make it
Thanks for your project help me in national Science Day
It also works with bc547 I have tried it
What is the ldr resistance
please add the circuit diagram for this project
Nice working night led .. THANK FOR IDEA.
Very best new project thanks for you sir
I saw this video and try it, it is not working like in the video 👎👎👎👎👎👎👎👎👎
True bro😢😢
Its working today i made this @@aagaming310
Its working
It's not working
Yes it doesn't work
VERY NICE CIRCUIT FULL WORKING 👌👌
Instead of a 1k resistor, I would recommend adding a 50k or 100k potentiometer so that you can adjust according to the room lighting.
not required for 3v power supply
Very nice video....unlike many other faulty circuit diagram on the internet...it truly works and works perfectly...I used a 3.75 battery with the circuit and it still works just fine
At beginning I said it doesn't work,
But now am saying it's work, the led will be high at beginning because the LDR is fasing what can be considered low light according to it size. Try different sizes of LDR and you will figure it out.
Mr. Nail Engineering 😃😃
God circuit you only bro😍😍
Great project! What I'd like to do is also power the led with an old phone charger. Can you give some help on that? A new video will help a ton! :)
Yes. It works properly. I make it by BC547.
can I use resistors with values of 520ohms and 1.2k ohms for this circuit ?
No, there will be more current in the circuit.
I tried this on my channel and it worked. The LED lights when light shines onto sensor
@OnboardingInformation Good job !
Could this be tested with 12v and if not what would I need to make it work with a 12v(3s lipo)?
Just connect a resistor according to ohms law formula of resistance
Nice
Sir if im using a battery with 3.6v what value of resistor should i use to power a 3-4v led?
3.6 V minus 2 volts for the led leaves 1.6 Volts. assume the LED draws 20mA R=V/I 1.6 deviided by .02 = 80 OHM. two 47 OHM is seris is close to 80
@@candlepower100 u seem really smart so i need some help what if im only provided with 9 V d.c. power supply, light bulb (2.5 V, 0.3 A), light bulb (4.8 V, 0.3 A), 3 L.E.D. and 2 resistors (180 Ω) and 1 resistor (390 Ω). sorry for all the trouble but help will be much appreciated :)
@@Sanjay-tc6hugive it to chatgpt as simple as that
I'm using it as a relay, thanks for the idea
Use flashlight on the ldr ,then the led turned off 📴
Works well, but power to the LED is lower, so the light is not as bright. Maybe a different resister would work better?
it needs to be 330 ohm resister ok!!!!!????????? and i have not watch this video yet thats why its been 2 months ok
Im asking sir if is it ok to use any type of npn transistor??
I have here 2n5551 transistor
You should be able to swap that out with out any issues. Just check the Datasheets, make sure you match up the pins.
NICE😍😍
Sir i did this with
bc 547
1k resistor
100 ohm resistor
3v led light
Ldr
Hiwatt battery
Sensor is not working light on directly what to do sir
Please reply
Thanks 👍
It worked thanks
How to do solar lamp same this idea
Can u pls give the circuit diagram for this
Can we few more leds instead of one to increase the brightness???
The circuit is not working
Please help me
Please upload the circuit diagram for this
Yes plz
Dear bro,
Why you use 10k resistor? I want to control white led strip(4v). Can I control white led strip(4v)?
You can use with it 12 watts 12 volts DC bulb also. I have tried successfully.
plz upload some fun like ultra sonic device projects
When the led is off current has continued?
Very good but is there any way to tryout with a bigger bulb...
Please tell why did u use 1k and 10k resistors?
awesome man!!!!!! The diagram be nice thank you for sharing.
Take a look at the Pinned comment from DIY Show, I've added a Diagram.
Can you please explain how this circuit is working.
there is voltage divider with 10k and photoresistor
transistor haves 0.6v threshold, if base-enitter voltage is smaller it will not open
when photoresistor have no light, it increase ohms and voltage drop on it is higher, then transistor opens
if it have light, it have low resistanse and voltage drop
Can i use 5v in this like powerbank?
El circuito funciona perfectamente pero ojo con el bc 547 hay que invertir el transistor como bien dice DIY SHOW
sir battery if add 9 volt instead of 3 volt will it work plz sir reply
Will it work if I add a 9 volt battery?
Pls reply fast
Want a video on 240v current circuit on this..
You have to do the Bridge rectifier. Search on youtube
Bro can you upload another video doing rhis on a bread board and with a c945 transister pls pls pls
Mara to automatic night light nahi ho Raha
This is great! How can I modify this so that the light goes off after a set amount of time, lets say 6 hours... What do I need to add to this circuit to create that functionality?
you can use this circuit to switch on the timer circuit....
add capacitors
@@musicalrainbow5438 Thank you.
What happens if I have a 10k ohm resistor and a 510 ohm resistor with a variable resistor
it works but not efficient it needs powerful light source to power of the light it not good in indoor use and its require to much power to get bright light from this circuit
Can i use all this components with a 1.8 volt led instead of 3volt?
Can we use 9 volt battery
you ought to change the resistors
Thanks you sir
next time you suggest using a BC547 instead of 2N3904, tell your viewers the pinout is mirrored .....
Wow,simple and useful circuit
It doesn't work for me 😭😭😭
Can it use 5v?
Can u please give the circuit diagram for this prohect?
Very low light, as it is a very simple ckt. Tripura
'
better use bright green LED or bright white LED...
blue light or red light LED is a too dark
How To Make LDR At Home
You just testing on battery sir but how to connect in ac switch in a board
Resister n 1k at base of Transister not required just short it, Instead use 330ohms in collector in series with LED to prevent its failure while using it.
How much voltage and current does this circuit support?
9v
Bro, did you teach me how to make it well, Kareena Bal?
Can you show me your schematic diagram for this
You do not need a schematic.
Pay attention to the video and draw the
schematic yourself.
If you are not competent enough to do that -
then go and purchase a commercially made
device - and find a hobby that you can work with.
Seriously -- I was repairing TVs and RaDio at age 8
and building RaDio's at age 10 c1948-1950
Qual componente tenho que mudar para colocar fonte 12 v e ligar fita led
wow big fake
Brh' it's not working 😢
Hi manisha kadam please read pined message😊
Does it discharge the battery when it's off?
Kitni bhi videos dekhlo kuch smjh Ane wala h nhi kyu ki sb sale alg alg circuit ya to alg alg components. Use kr rhe h 😂
Can u give me this diagram where the light is the last ti be added
My one is working thank you so much
Work the circuit thanks 🔥
you are using different components than showing in thumbnail, how can we trust on your circuit.
Hey, I wired my circuit like that but for some reason it will only turn off if I shine a strong light (such as my phone's torch) directly into the ldr. I'm making a card game board and I want the light to be off until the ldr sensor is covered by a card. ..so basically it's not working like yours. xD any help you can offer would be appreciated man
Hi Lord Weird, try adjust the value of resistance
there are other ldrs where the bulb glows during the day and goes off at night . can u pls explain both the phenomenon
Did I see finger nail cutters!!!!!
If I ned 12 leds to shine can I modify the cirkuit in some way?
replace led with led-wire ( found as Christmas battery led-wire . cut of 12 leds )
Useful video congratulation
To Ka kara
what will happen if we put 12v in to it
Just want to ask sir. What if im gonna use any 12v led headlights.. what are the components adjustments to be use..?
How can I get the sensor signal
attach to 3 9V batteries and touch it with your tongue
Sir mera led bulb flicker kr rha h what's the solution ?😢
Resistor ki value kya h 10k resistor
Quarter half me ya h dusri value me.
Why does my project does the opposite? It turns off the light in tue darkness
he made a mistake LMAO
l will make it today
Use I Bc547
Need for 2 pard 😊plzz सनद fast
I tried on bread boat. But it did not work?
Can I use 3.7 battery
Yes I think , you can give it a try 😊
Thanks brother

Can we use without resistance
No
How can i get components at low cost
i use 2N3904 but it doesn't work will, its always on
Sir, If I want to received light and LED is 1. What should I do
Bhut jada fake video h or isse esa kuch bi nhi hota mne bi krke dekha h ye ab bekar h ye payal bnata h
