VERY GOOD

[@keithking1985]

Just what I need for a little project 😊👍🇮🇪

[@MDMohsinMubineditzfromBD]

WoW

[@vobinhthu5299]

This project is very good!

[@sm_electronics]

Thanks bro....

[@ananddhanesan8275]

NICE MAKE, LOVED IT

ভাই পুলিশের সাইরেন কিভাবে বানানো যায়। পুলিশের সাইরেন বানিয়ে একটা ভিডিও দেন।

[@sdmhacks1381]

Very thanks for it👍👍

[@sm_electronics]

Welcome

[@MohamadTaki-md9df]

احسن....عمل صحيح..

[@sm_electronics]

thanks

[@Bianchi77]

Nice info, thanks :)

[@sm_electronics]

Thanks for the comment.

[@zombeie]

Can we change its tone if we put a variable resistor? If yes then which one and what's the value?

[@sm_electronics]

Good thinking...Any value between 100k to 1M

[@LidarSpeed]

it's only work with BC547 and 557? I tried on others as C1815-A1015, 3904-3906, SC1623 ,all not work

[@sm_electronics]

See the pinout of the transistor.any npn and pnp combination will work like 3904 and 3906.

[@techgautam422]

ভালো উচ্চারণ।

[@sm_electronics]

অনেক ধন্যবাদ😍😍😍

[@ekosutedjo318]

pakai aki 12 vol bisa gk mas?

[@sm_electronics]

Using 3.7v battery.

[@RameshPal-cd4cs]

Circuit diagram?

[@awmkarawmkar3208]

can I use a buzzer instead of the speaker?

[@sm_electronics]

No.it is only for speaker. Use buzzer directly. No need for circuit

[@6d2hi.original]

😊 Thank 😊 you 😊 so 😊 much 😊 sir 😊

[@sm_electronics]

Thanks 😀😀😀

[@navjotsingh.3766]

Maine bhi banaya tha Lekin awaaz bohut kam Ati hai aur loud kaise karu Please reply dijiye loud kaise kare

[@sm_electronics]

speaker change karke dekho

[@navjotsingh.3766]

Agar is circuit se do speaker chlaye toh ye work krega Mere pass pnp transitor nhu hai

[@tuningfetiyati7420]

can i use 2n3904 or c945 or 2n2222a transistors

[@sm_electronics]

yes but use one npn and one pnp transistor and see the pinout

[@tuningfetiyati7420]

Thank you

[@bahadrozcelik9416]

Can i supply 12 volts

[@sm_electronics]

No.Then the Circuit will be damaged.

[@FrancoLavoreCenturion-mb1qd]

Hello, good video, how can I make it sound louder? thanks greetings!

[@FrancoLavoreCenturion-mb1qd]

I have already changed the speaker several times and the sound is still low

[@sm_electronics]

use 5w 4inch speaker. if you are not satisfied use a buzzer. thanks for the comment friend.

[@FrancoLavoreCenturion-mb1qd]

@@sm_electronics Thank you very much, greetings from Argentina friend!

[@olayaamatoallah5238]

Hi sir! Can I use BC548 instead of 547?

[@sm_electronics]

yes

[@amitvinayaka]

Super😂

[@sm_electronics]

thanks 👍😁😁

[@syedzulqarnain457]

I know English. I cant understand your language.

[@sm_electronics]

make the circuit as shown.

[@asifkhokhar8404]

Kya is se water alarm bana sakte hai

[@sm_electronics]

Yes friend 😃😃😃

[@Tonosdepougraciososcanal-eg7tq]

muen project muito buzzer speaker com transistor

[@yamlalkandel5397]

Can I change BC 557

[@sm_electronics]

Use Any PNP transistor

[@rumintimansilalahi3672]

Apa jenis kapasitor itu

[@sm_electronics]

ceramic disk capacitor. You can use 0.1uf any type

[@rumintimansilalahi3672]

Vai normal buzzer er market price koto?

[@sm_electronics]

10 থেকে 15 টাকা

[@circuitprovedlab3030]

not working. same to same sb use korlm. transistor gula o testing kora trpr korachi. ta o not working..!!

[@sm_electronics]

Circuit a bc547 o bc557 transistor ache. Amake [e-mail] a tomar. Toiri circuit er video o chobi pathao.

Use speaker not Buzzer

[@Manisha-mv4bz]

Not working properly
