GREAT JOB NICE PROJECT
Always on top thanks
Nice bhai very informative 👍👍
😉
Thank you dear you're Alway following ❤🎉🎉🎉
So nice thanks
Very very👍😍 nice Bhai
Kal me bhi ldr ko cutting krega 🎉🎉 Always follow and replies ❤❤ on you're channel ❤❤❤
❤️❤️
Thanks 😊
A ka sachme Kam karta hi😮
Yes
Nice one.. tnkx.. i will try this diagram.. oh, what if i wanna use an 12v led light, and 12v of batteries. What are the adjustments of the other.
Thank you sir
Nice project👍
Brilliant idea
Thanks 😊
thanks for knowledge
👍😊
Good
Thank you
Kya baat hai bhai

Cutting with hecksaw blades _?? 4:55
100% वरक करता है।
Kam karta hai bro
Nice
Thanks 👍
Thanks brother ❤but without Bc547 and 100k resister Kya ye banskta hai❤
Nhi bc 547 is switching transistor. Matlab on/ off ka kam to transistor se hoga ji
Sir hame 1 2 cut karne hai ya 3 4
Cay this is work
Vai isse kiya 12 volt ligh pe kam karenga?
Yes always
Ha apko malum hoga ki charger ke output point me 4.2 v niklta hai
Wha per 12v. Ke Electrolytic condencer connect hai plus or minus me to matlabi saf hai ye kam krega ldr.🥰
Really working or not
CAN USE 9 V BATTERY AND PHOTORESISTOR AND LED IN SERIES WITHOUT RESISTOR?
👏👏
Kya ham is sarkit ko 220volt me chala sakte hain ya nahi ?
No
Bhai transistor kaha se gilay ga
Online or kisi purni tv ki dukan per ya Electronic shop pe
Kisi bhi supply me milegi ye under 12v dc. 3:22
I'm afraid your circuit diagram is wrong in supplying negative 3.7v to the base before the ldr instead of giving it direct to emitter.
Answer jaroor dena charger sahi tha ya kharab
Mera wala charger sahi tha but kharab charger me v optocopuler 95% time good condition me hi rahta hai 😊
