Hello ! I tried nearly everything you showed us... Thank you, I learn a lot with you !!! I would like to know how to adjust (dim) a 12vdc led ruban reverse to the day light. I mean, when it is dark, the leds are at 20% and at 100% under the Sun... It must follow the daylight and modify the luminosity of the leds in the reverse proportions. This is why I was thinking to use ldr... exemple of use : a picture to be highlighted in a room ... Lot of light when it is clear and less when it is dark. Thank you and go on with your ideas...
I downloaded your video to my phone. I will also build a light sensor. I have installed several surveillance cameras in my yard and the light sensor will turn on the IR LEDs at night. Thanks for the ideas !
It's 5 ways to use a component. Says in the title. All practical and cheap and easy for inexperienced enthusiasts. I think it is well done. Good reference for everyday applications of which there are many projects to be done unless you have no imagination. Have a great day.
Thank you very much and already practiced, very satisfying. NE 555 for daytime BD140 for the night. The best circuit that can be used directly on the device.🙏🙏🙏👍👍👍👍
Valeu! Ótimos projetos! Grato! O LDR são um componente muito interessante e ultimamente me parece um pouco "esquecido"... bom que você nos trás mais que uma lembrança e sim a importância de um ótimo componente e alguns ótimos projetos com os mesmos! Show de bola! Abraço!
Bonjour, as tu une réalisation avec une photorésistance( LDR) qui lorsqu"elle ne détecte pas une flamme au bout d'un moment couperait un relais 12 volts ??? Un bonjour de France
3.9 k or 4.7k,,,,,,,,, but remember 5 volt can burn the 4 volt led light you must use 15 ohms/ 1watt resistor between 5 volt supply and led light,,,,,,,,,, Thank you for interest,,,,,,,
Hello, it is for a boiler a little special, I want that when starting, if the cell does not detect flame after a few seconds, it cuts a relay. All this in 12 volts. Thank you very much and good luck to you.
Great job. What are showing to the people. Where are the safety equipment. How you can work with electric like that. I know the power as so low but what the people will learn. If any one tries this with 220V without PPE who will be responsible
I know these are rough and ready projects but every time I look at the soldering tip I really want to take that soldering iron and put it where the sun don't shine ... No, nothing to do with flux!
Bonjour , c'est pour une chaudière un peu spécial, je voudrai que lors de la mise en marche , si la cellule ne détecte pas de flamme au bout de quelques secondes ,elle coupe un relais . Tout cela en 12 volts . Merci beaucoup et bon courage à toi.
@@ABTabi Dear ABTabi, I would like help building the following: An LDR circuit that is powered by a 12v battery so that simply when a laser hits the LDR then it instantly activates a solenoid to ping a bell. That's it! Ideally I would want around 7 LDRs in a cluster to make a larger target area. If you can design and build this so I can copy it and reproduce it in the UK I will pay you for it via PayPal or Western Union it's fine. If you want 50% up front and 50% after it is complete that is also fine. Take care :)
Abi,, im 600th like, i never see u use diac db on your project, how long live time ldr if we use on street lamp? And why on dimmer ac motor triac have to use cspasitor and diac?
Dear friend thank you very much,,,,,,, diac not necessary for every project,,,,,, ldr work for long life if you make it waterproof,,,,,,,, for speed control of ac motor very low to high,,,,,,,,,,,,
The project is verynice...please make scema circuit👍👍👍

Hi Bro...can we use BT136 instead BT138?
Can you please explain the concept behind BT139.......part 4...., and how much load it can take?
Спасибо! Без слов, но все понятно для 😇начинающих, схемы 📝прилагаются! Жду продолжения!😀
Dear friend you most welcome ,,,,,,,,,,,,,

Will the first one work with 12v?
2.7k ke jagha kon sa resister use kare 😐
excuse me for the first project how can i make the led light up when in bright condition instead of dark.
I already uploaded ,,,, but i will make it again very soon ,,,,,,,
This guy needs to take a class on soldering.

Can we use 3.7v battery and 3.7 v led
merry christmas you're so kind and knowledgeable sir I have a question why did you Use a capasitor across from bulb? for decreasing voltage?
Thank you very much my dear friend,,,,,,,,, control to voltage,,,,,,,,,,,,
I didnt understand why must it be controlled?
ali behrouz it's not required ...
Can we not use same circuit for 7v, 9v, 15v LED bulbs?
Abhishek maurya yes using a BC 547 transistor since it can handle small voltages have low input impedance and high output impedance ..
It's important to use heat controller ?
coool thanks please the software that you have used for traitement of your video thks

Brother I need the same but a reverse process after falling light the led should glow
Dear friend ,,,, i will make as soon as possible ,,,,, Thank you for interest ,,,,,,
Very nice 👍
Thank you 👍
What would have to change for the LDR light switch to make it work for a 120v AC circuit? Thank you.
I think you would need either a voltage regulator or stronger led strip as it was only 4 V
Valeu!
Ótimos projetos!
Grato!

can u make a video on how to connect this circuit with the battery for backup to a solar panel ??? pls
Just another question. If i change the input to 5v, what would bij de resistorvalue?
My dear friend please tell me project No............
It is for the project with the 4 volt battery and the 4v led, and the BD140.
3.9 k or 4.7k,,,,,,,,, but remember 5 volt can burn the 4 volt led light you must use 15 ohms/ 1watt resistor between 5 volt supply and led light,,,,,,,,,, Thank you for interest,,,,,,,

Please make a video with 6volt mini solar panel,4volt2ah battery,5volt relay and ldr.
