What a idea bro 👌👌👌👌 Really it was nice I was confused after watching other videos but when I watch your video I understand everything .. Thanks bro👍👍👍
Can we use a normal laser light for it? And can u pls send me materials that are required as u put usually in description box but their is nothing in it Your videos are very awesome and I try these every time
TODAY SUDDENLY I WATCHED YOUR'S LEZER SWITCH CIRCUIT,YOU BETTER THAN OTHERS,BUT YOU DIDN'T SHOW ON SCREEN THE CLOSE UP OF COMPONENTS,YOUR EXPLAINING OF CIRCUIT FUNCTION IS VERY GOOD,SO IMPROVE LITTLE BIT,THIS IS MY HOBBY,I SUBSCRIBED YOURS CHANNEL.PANNU BOLLYWOOD ACTOR.
Useful circuit Sir, kya me shi hu ki?? Jab LDR pr light nhi gir rhi hoti h to LDR ka resistance less ho jata h, or 10k ka pura current ground pe aa jata h.jisse bc547 off rhta h and jisse buzzer bi off rhta h. Sir, kya es time anode and ground k bich, 10k & ldr k through short circuit/power loss horha hota h???????? Jbki LDR pr light girne se resistance high hota h,and 10k ka pura current bc547 ko hi milta h.and bc547 on ho jata h.jisse buzzer ko supply mil jata h ,or bzta h. Plz tell mer sir.
Hum ne same banaya h par Jb hum laser ldr par marte h Tb buzzer ki sound km hoti h And jb hum laser and ldr ka connection break krte h tb sound Jada hoti h Is there an effect of intensity of laser light? How much volt battery u use in laser light? Can u help us asap till the evening???
Sir laser and LDR mai maximum kitne distance pe ye ckt wrk kr rha hai.. Cauz video mai jo distance hai wo daily life mai practical use pe implement nhi hoga.. Like 5-6 feet distance gap hoga tb ye wrk krega kya ?
I have used a BC 557 Transistor and the buzzer is buzzing only when some light falls on it. Is it because of the teansistor or there is some other kind of mistake? Plz.... reply fast.
Bhai isme to jb tk laser k samne rhge tb tk sound aayegi esme kya kre ki ek bar gujre k baad sound on hi rhe jb tk hum off na kre reply jldi dena 1 like meri trf se
Sir I want to know that from which thing we can get LDR .Because I m not getting it in market + If we can make a LDR at home pl. Tell because I want to make this project in school science comp.
Battery kitny volts ki honi chaye?? Or agr 1k ka resistor lgaye to kia ho ga?? Mtlb k chota resistor ku ni lg skta or battry itni he volt ki ku honi chye
Hello.please reply Buzzer is continuously working Kya yeh buzzer kaharb hai isliye ho rha hai . Components toh sab sahi laagye hai Reply as fast as you can
Sir, mene ye circuit banaya lekin mera ye opposite work kar RHA hai.ldr par light daal rha hu to buzzer chata h. Or,light htane par buzzer ruk jata h. Kya karu plz...sir batao ?
How can I count that How many times obstacles occurred Can some one please share a code No alarm for continued on and off obstacles But if there no obstacles for 1-2 min then alarm will sound How can I get codes for this Please share Thank you
I'm from bangladesh.

😂 😂 😂 thanks
Congratulations for 💯 k
Thanks
"Thank GOD", and thank you very much for your support and time 😉 What is the MAXIMUM range of this unit 🤔 PLEASE let me know 😎
as far as the laser can reach without fading...it is different for different lasers
Useful circuit
Sir, kya me shi hu ki??

Sir, kya es time anode and ground k bich, 10k & ldr k through short circuit/power loss horha hota h????????
Jbki LDR pr light girne se resistance high hota h,and 10k ka pura current bc547 ko hi milta h.and bc547 on ho jata h.jisse buzzer ko supply mil jata h ,or bzta h.
Plz tell mer sir.
Yes
100 % orginal ha s try it bhat hi acha ha keep it up big love big respect
LDR ka koi lag +v/-v hota he ya nhi?
Koi v side me connection dene se pblm hoga?
No
Thanks for video
Red laser light
ko ldr par Dalne par band nahi hot ha
Sir kya hum koi sa bhi resistor use kar skte hai????
Kya Me buzzer ki badle dc motor lega sakta hu
Thank you so much sir.... This helped a lot than any other video
Very simple concept thanx bro
Jyada sound wala chahiye....
Hello sir very nice working range butween circuit and lesagar
Depending of lesar light
Video mast he 👍 sir ji but 2nd part bhi la sakte ho is video ka jo ki related ho infrared sensor LED Light security 😄
?????
Hum ne same banaya h par
Jb hum laser ldr par marte h
Tb buzzer ki sound km hoti h
And jb hum laser and ldr ka connection break krte h tb sound Jada hoti h
Is there an effect of intensity of laser light?
How much volt battery u use in laser light?
Can u help us asap till the evening???
Sir ap ne logic gats pe video nhi banai , plz banain jis men koi circuit use kren or bataen k us circuit men logic gat kis tatha kam kur raha h
Ji haan dosto main Ho KANTI or ROBOTICS pe apka swagat hai 👍😆

Aapko follow kia sbhi connections same kie h but mera buzzer battery lgte hi bolne lg jata h i want to know the reason plzz
Sir can we use bc548 instead of bc547
Ok
Kanti Sir. .kesa speaker lagao
You can reply in bangla..
Video ma bole diyechi dekho video
Sir, mene ye circuit banaya lekin mera ye opposite work kar RHA hai.ldr par light daal rha hu to buzzer chata h. Or,light htane par buzzer ruk jata h.
Kya karu plz...sir batao ?
Ulta lagaya positive and negative wire
Robotics no sir mene apke video ko dekh kar hi lagaya h.
Mera vala light detect kar RHA h.light milte hi buzzer sound nikaal RHA h.
Bhai es me .r.kon Kon si laga skte h ..
Plzz reply fast..
Kiya
How can I count that
How many times obstacles occurred
Can some one please share a code
No alarm for continued on and off obstacles
But if there no obstacles for 1-2 min then alarm will sound
How can I get codes for this
Please share
Thank you
Sir 10k rasister na dene se chalega?
Best video for experiment
