Nice diy electronic projects and knowledge, thanks for sharing 👍😀
I used to make these simple circuits when I was a teenager. That time there was a popular L.D.R , the ORP12. These circuits seems that they are simple and they are BUT these are the basics of more complicated ones.
Thanks for posting these and as always keep up the good work.
Thank you very much

Gostei de ver
Really nice!
So simple circuits, but still fun and useful
simple idea using LDR, very creative. I'll try it ...
very nice sir Thanks you for your sharing sir
Thank you very much, I found very useful this video!
I love you !
I love your channel !
Please more videos
please more videos of simple utilities
👌👍😗🤗🇪🇸
Молодец!
Nice video my frined kepp going
Nice 👌👍😍👏💕
Nice one the ckt works fine for led switching control,verified (y)
Will try with dc motor loads.
Good❤👍
Great
👍👍👍❤❤❤

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? :)
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.
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.
Don't stop producing these videos.
100/100 power full
This is photocell application . Dusk to dawn application. Can you do proximity sensors or motion sensor?
En el segundo video serviría una tira LED a 12 volt?
Please make a video on password lock system using 4017. It's an humble request.
Less than perfect credit? Yes Problem! Easy Approval!
As u have shown to connect the controller ,if we don’t want to and connect it with 6v 3W solar
6:52, connect two emitters together? Or is it the base?
Light Dependent LED Blinker ko 12v supply pe chalany k leay Capacitor or Resistor ke Value kiya rakhni hai.?
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.
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
دائما تستعملون ايسي bc547 . بحثت عنها كثيرا بين الاجهزة التالفة ولم اجدها للاسف .
hello sir
aisa kya kre jo ldr ulta work kre
jese din me light chalu rahe or andhera hote hee band ho jaye
You know you didn't tell us anything as the value of the LDR is very much needed.
Sir second project ma 3 volt circuit kaly a kitne volt ka resistor laghe gha
can i use 10 uf capacitor
Please show schematic to circuit. I want to use these in class.
In second LDR circuit why you use 33k register ? Please Reply!
Bro please upload circuit diagram
Same problem 😭😭😭
It's easy to draw one by yourself , just draw all the components and connect them as shown.
@@arnbon6241 thanks for replying bro🙏
I think the circuit Diagrams, do show up in this Transistor circuits video.
Bro 9w led bulb mosation sensor ciruet plz.
sir me ldr ko soldiers kiya
mera surcuit kiu kam nahi korta he
First one is glowing off when there is darkness
How to make a system to LDR that lights up for 15 minutes when someone goes in front of the light
Should be LEDs -ve to Collectors
bhai aap Ne relay wala circuit ac hai dc hai
Can I used 12 v supply and 12v realy sir
*Please give me a value of resistance instead of plot.*
A pot is used instead of a fixed resistor because if you use a fixed resistor you can't alter the sensitivity whereas by a pot you can. So in this circuit it is a must to use one.
@@arnbon6241 but u can give me a fixed value of resistance on which sensitivity will be highest, from this video
@@WWEMaster I can't tell you without building the circuit but if you really want a fixed resistor instead of a variable ( which I see it's pointless) just at first use a 5k pot , calibrate the pot at your best sensitivity and then with a multimeter measure the resistance of the pot and make a resistor with that value or nearest.
220 how many vt
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.
3rd
Thank you
Reley kitne volt का होगा
12v
Total cost
I have no 10 k potentionmeter
fourth circuit is not woking properly
It is not good
copying...boring...
In second LDR circuit why you use 33k register ? Please Reply!
To keep the transistor ON, ldr will try to OFF the transistor when there is light
@@TechIdeasAG ohh, Thank you, sir! Which register need for my 11volt 3watt LED bulb?
