⚠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
😂
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
Wow,simple and useful circuit
Nice working night led .. THANK FOR IDEA.
Very best new project thanks for you sir
its very informative but plz do tell in more details. i love to see this. stay blessed.
VERY NICE CIRCUIT FULL WORKING 👌👌
I'm using it as a relay, thanks for the idea
Useful video congratulation
Nice project
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🥲
good job 👍
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.
Work the circuit thanks 🔥
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! :)
VERY NICE👍👍👍
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
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
Bro i like the most i have seen ever
God circuit you only bro😍😍
TU PROYECTO ME GUSTO Y YA ME SUSCRIBI
Cảm biến ánh sáng của bạn rất tuyệt
Great
Can i use all this components with a 1.8 volt led instead of 3volt?
Mr. Nail Engineering 😃😃
It worked thanks
Very good but is there any way to tryout with a bigger bulb...
V nice
thank you
Nice
This is really working and my project is also working
Yes. It works properly. I make it by BC547.
Thanks you sir
Thanks ❤️
thanks a lot
NICE😍😍
Qual componente tenho que mudar para colocar fonte 12 v e ligar fita led
Just want to ask sir. What if im gonna use any 12v led headlights.. what are the components adjustments to be use..?
Very best project thanks for you sir
Thanks for your kind comment
Its good
😅😅😅😅😅well information good show 😅😅
please add the circuit diagram for this project
Can i use 5v in this like powerbank?
weldone
El circuito funciona perfectamente pero ojo con el bc 547 hay que invertir el transistor como bien dice DIY SHOW
Thnx
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
Can we few more leds instead of one to increase the brightness???
plz upload some fun like ultra sonic device projects
Can it use 5v?
3v white led is good?
Please tell why did u use 1k and 10k resistors?
Ok for pilot projects.Will not work properly if light is changing slowly. Use a 555 of opamp for triggering at different threshold
It works , but use breadboard for testing before solder
Good
Thanks
Does 2N3906 transistor is works for this project sir.
Can i use a mobile charger for electric supply?
Good...how to use higher volt ?
How many hours does it light up?
👏👏👏
👍👍❤❤
Mene complete kr liya
Is work when I use 12v battery and 5v led???
👍
Can I use 18650 battery for input
When the led is off current has continued?
We can use s9014 ?
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
Can u pls give the circuit diagram for this
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.

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
can I use resistors with values of 520ohms and 1.2k ohms for this circuit ?
No, there will be more current in the circuit.
Sir, If I want to received light and LED is 1. What should I do
Can i use Big LDR
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.
👌👌👌👌👌👍👍👍👍👍👍👍👍👍
Can we use bc 548
The light is always on how can i fix this? I used two same resistor
How about adding a small solar charger to the circuit??
how to adjust sensivity to light? for example with low ambient light the LED be completly ON ? Thanks.
Hi Hosein Goodarzi , just try adjust the resistor which connected to the base pin (the middle pin) of the transistor , replace it with a variable resistor :)
Try this circuit drive.google.com/open?id=1RDHIf5pWHxdee7DyUaPWujMtFJ4HyRdP
Thank you so much. I will try it
@@diyshow888 is it working for 5V DC?
How can we operate this circuit with AC supply
Hi person who made this video , super awesome content , but u see the part when u melted the thing a little so it can stick ,can u also just use a tiny piece of insulation tape or glue or something to stick them together?
It's named pond, it's used for tinning machine, i don't recommend to use scotch tape. I recommend to use the tinning machine
Just buy a 75 r soldering iron and soldering wire of 20 r from quarts components
Es ckt ko AC components me kar sakte h 230Volt
Bro if we off the room light then it will glow? And pls let me know the terminals of the transisters and light
can i use a 9v battery
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 )
Can i trigger a relay with this circuit?
Can u give me this diagram where the light is the last ti be added
How to do solar lamp same this idea
Can i use 9v battery??
Thalaivaaa❤️❤️
Can we use S8050 Transistor
Can use 12v
Power full surcit
Olá bom dia Posso alimentar com 5 volts Agradeço se puder me responder Obrigado
Bro can I use bc 557
Would this work with a 7.4V batery and ofcourse a 7.4v led??
yes
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
how can i use this circuit for my switch which is 220v
