3 Useful circuit based on BC547 & LDR 

Excellent presentation in a very simple way. Thank you very much.

Hi, tks. value Capacitor of 2nd project?

Bohat achi videos Hain ap ki Bhai mera aik sawal hai kia main is circuit ko 12v DC sai operate Kar k 12v DC ki koi thing chala sakta hon like main solar panels ka single axis sun tracking system banana chata hon kia yeah circuit sun tracking main Kam karay ga car ki viper motor lagaon ga for moving solar panels. Please guide me I'll be very greatful to you. Thanks

Sir is me koi variable lag skti k nai jis se hm light ko kam ya zyada kr k light ko on off kr sky?

second project...I can use 6 volt relay or not? and power supply also 6 v it is working or not

What is the input of your last project. Is it 12v?????

Bhai working theory ke baare main bhi bataya Karen thank you

Excellent I am interested to make in 230v AC please let me know what all values of components needed to use please share me the circuit diagram also please if you don't mind please let me know your reply

Very good mein bhi yahi teesra project chahta tha ok by thank you. Alram ke liye. Thankyou

Sir, good video.but mere pass ek ldr h jo 16 v show karta h n usse me 4v dc led strip kaise auto cut mode me chalau bataye .mene bc547 ke sath use laga kar dekha but kuch nahi hua

hello bro .....about 3rd project what the source of DC and the LED how much voltage , you make the LDR work at light i need it work at dark , how do i do that

Soo easy & very useful project, his presentation is also very nice. Thanks brooo

Sir bahut lajawab aur zabar 10 he

Hi, i like your number2 project. I want to operate 3kw lode. Please reply which components should i use for this. Also please mentioned the components details. Thanks,🙂

Brother Mujhe Bike Ka Headlight Automatic On/Of Karna He 12 volt To 18 volt Tak To Usme Kiya Kiya Chahiye?

The way you explain the details are very nice

Bhai agar muja 1 min delay kar na ha to kitnai uf or v ka capacitor lagai ga plz bro reply

आपका प्रोजेक्ट बहुत अच्छा लगा

For beginners it would be helpful if components name & it's nomenclature/rating r displayed while using that component & also provide circuit diagram.

mujhe aye video bahut ache lage kinyu ki ishse mene kuch sheka par bhaiya ji aye saman to milraha hi nahi hai ap hi bataiye ldr aur kaha milega

Sir Capicator ka rating 400V, 2.2 . Micro F ka laga sakte hai

Nice innovation...👍👍👍🌹🏵️ Very nice useful projects...... U are great brother.....

By using LM324 u able to use any type of senser like motion senser ur LDR etc. Interface between 8051microcontroller with a sutaible programming and see its a waoooo its real project like major project of electronics

Vijay bhai great ideas for sharing with us Thanks a lot

Hi,my project based on automatic upper dipper in vehicles but it's not working properly.

Bhaiya ji jo jo saman istemal karte hai project banane ke liye discription me vo Apne koñse online Shopping app se mangaya hai ya fir khade kharida hai ya uski list de diya kijiye please Adani hogi Ap samaj sakte hai shayad .

Very very good sir ji 1000 watts Lod system banaen sar ji LDR SE AC our DC12 volt relay ke sath

very nice bro

1st prjct me 220 AC +9volt DC laga sakta hai kiya?

Thanks bhai 3 project sahi hai 👏

Kya ldr ki jagh koi upkarn laga sakte h

Second project me jo DC transistor aur relay me diya hay vo kitne volt ka diya hay o btao plzzzzz btao o project may bana raha hu To plzzz reply Me

Keya hum ye circuit ac volt main use kar sakte hain

Thanks

Extremely nice project sir👌👌👌

good concept about transistor switching activity

What type of current are you giving to the 3rd project

Hello sir 2 nd vala project me ham chota led use karana chahate hai 9 volt ke battery se jodakar to kya kare please aap usapar video banaye

Nice idea.

Fantastic and. Useful video

बहुत शानदार

Kya iss third video ko MCB se bhi connect kar sakte hain

Sir how many volt is required to operate rely

Bhai ldr kahan milega matlab kisi charger me ya kisi aur me

In which device we can find ldr?

Very good project

Expalin transistor practical working.. How is current controling with the help of LDR

आपके प्रोजेक्ट बहुत अच्छे लगे Thank you sir

Can we use BC 548 transistor? Plz reply! 🙇

Thanku bhai but apko circuit diagram bhi sath mai upload kiya kro aur components name buy link

Hola ! Con BC337 finctiona ?

Bahut accha laga

did you connect with 220V The first one

Best projects. I like.

Awesome videos sir ji

Tanester 574 ki jagha konsa kaam Kar Sakta h sir

Good idea

Nice Projects

nice project but you should give circuit on paper thanx

3no project mst he , ho ske toh jo 3rd project aap watch me lgane wale ho uska bhi video ho ske toh share krna.., Thanks 4 give buying link

diagram aik paper pe bana kar dikhaya karen, ap ki videos achi hoti hen sir .

Very nice and beautiful project Sensor Kaha milega

Nice Bro, Love from Pakistan.

Nice bhai ji

Projekt very good

No word for your wonderful work

Sir please explain the working of first project on diode connection

Meri taraf comp nii mil rhe hai koi shasti achi site btaye nevon ke alawa thanks

Very nice

Wow great idea

Third one was inverted. It should turn on in the evening and switch off in the morning.

LED matrix DISPLAY par koi project banao boss.

Capacitor ka number kitna hai means kitne farad ya kitne micro farad ka hai

Bahut badiya

Sir koi 12v fast speed led blinker bnaiye jisme preset lga ho. Aur thoda aaram se explain kijiye plz sir

Very nice sir

12v LED Strip ON karna chahta hun LDR use karke woh 12V DC supply ke sath, bina Relay use kiye kese karun.

Amezing broo..

Bhai mera 33k se nhi chala but 100 k se work kr rha h LDR project Thanx

Bhai video both acha ha asi hi video bhanata rahana

can we use bc 548

Very good project 😍😍

Motion sensor per bhi aik vedio zaroor banaien.

Awesome bro

Aap video mein circuit diagram jarur dia karen Achhe project aap ne dikhaye

Street light par lagane k liye ldr switch kaise banaye jisse k light ki barbadi roki ja sake please upload your video

awesome projects sir, keep it up. you doing a great job

Awesome video & fantastic Presentation 😊👍

Super bro good job......

Good iam srilanka

Nice project

I liked this video

Useful video👌

Mxt or bhai 1 baat h ki pta kse chlta h ki kon se wire Kahan par uh jodne hai

Full useful project

If u add Circuit diagram in your video then it will be easier for us to make this project.

bhai 3.7 to 5v canvert karne bala kit banao

Why have you connect black wire in 2nd project while you have already connected 230 volt current by plug

very good

Sir apse request hai ek touch less sanitizer machine baniye plzz
