4 Type of easy LDR circuit

Gostei de ver

Во 2-й самоделке вы питаете LDR 10W через транзистор BC 547 максимальная мощность которого по даташиту - 0,5 W. Это только мне кажется, что такая конструкция долго не проработает? :)

can i use 10 uf capacitor

Great

It is not good

copying...boring...

Meu irmão, no terceiro circuito você ligou o COLETOR ao negativo do led, e não o EMISSOR; ao menos é isso que parece de longe; pois parece que o transistor está de frente. Valeu pelo envio. Saudações do Brasil a todos.

bhai aap Ne relay wala circuit ac hai dc hai

hello sir
aisa kya kre jo ldr ulta work kre
jese din me light chalu rahe or andhera hote hee band ho jaye

Total cost

Dear Sir, In first LDR controlled 230V lamp circuit, can I use 12V DC power Supply for this. If I am using 12V DC power supply what are the components(Value) to be use. Pls Help

100/100 power full

fourth circuit is not woking properly

Plz tell your number

SIR: VERY PLEASED WITH THE FIRST TWO PROJECTS. I THINK THE THIRD VIDEO IS WRONG ON THE DESCRIPTION ON WHERE TO CONNECT NEGATIVE OF LED. YOU ARE CONNECTING TO THE COLLECTOR AND NOT THE EMMITER. THEN, WHEN CONNECTING THE TWO EMMITERS YOU ARE WRIGHT. THE TWO THAT WERE CUT AND JOINT TOGETHER ARE OK.

In second LDR circuit why you use 33k register ? Please Reply!

In second LDR circuit why you use 33k register ? Please Reply!

very nice sir Thanks you for your sharing sir

You know you didn't tell us anything as the value of the LDR is very much needed.

Good❤👍

I have no 10 k potentionmeter

Thank you very much, I found very useful this video!

How to make a system to LDR that lights up for 15 minutes when someone goes in front of the light

👍👍👍❤❤❤

As u have shown to connect the controller ,if we don’t want to and connect it with 6v 3W solar

❤❤

First one is glowing off when there is darkness

sir me ldr ko soldiers kiya
mera surcuit kiu kam nahi korta he

220 how many vt

Less than perfect credit? Yes Problem! Easy Approval!

सर मुझे आप से बात करनी है ...

या फिर आपका नंबर दीजिए.... प्लीज

Should be LEDs -ve to Collectors

Light Dependent LED Blinker ko 12v supply pe chalany k leay Capacitor or Resistor ke Value kiya rakhni hai.?

Nice one the ckt works fine for led switching control,verified (y)
Will try with dc motor loads.

simple idea using LDR, very creative. I'll try it ...

I love you !
I love your channel !
Please more videos
please more videos of simple utilities
👌👍😗🤗🇪🇸

Sir second project ma 3 volt circuit kaly a kitne volt ka resistor laghe gha

Please make a video on password lock system using 4017. It's an humble request.

Please show schematic to circuit. I want to use these in class.

Really nice!
So simple circuits, but still fun and useful

Can I used 12 v supply and 12v realy sir

Why is it that 240volts is used rather than low 12volts. Your video goes out to i would imagine young viewers getting interested in electronics. Not only is the voltage lethal, but you have the whole assembly with the 240 volts not protected, ready for waiting fingers. As i said, using 12 volts is more than adequate for the learners to start.

Reley kitne volt का होगा

Молодец!

Dude, please build a metal detector for both ferrous and non ferrous metals (should there be a difference). I'm sure you'll get plenty of views. Build circuitry with practical applications, I doubt whether most people know the physical application of your circuits. Anyway great work, don't stop.

دائما تستعملون ايسي bc547 . بحثت عنها كثيرا بين الاجهزة التالفة ولم اجدها للاسف .

Don't stop producing these videos.

Nice video my frined kepp going

Nice diy electronic projects and knowledge, thanks for sharing 👍😀
