Buzzer Beep sound effect, Science project with Transistor

[@Majuscule2012]

Thank you so much, am searching something to never forget the top beacon after leaving a construction site!

[@homemade_101]

good luck

[@Aaliyah21]

Nice idea 😎👌

[@homemade_101]

Thank you..

[@Creative114_]

Nice

[@siyabongankosi9956]

why is the base not connected to anything in the transistor, you just cut it...What activates the transistor then?

[@homemade_101]

yes😇

[@ИгроваяШляпа-д5х]

Because it is pnp, base need be 0 to activate

[@dileepsharma8538]

I use 4v
Can i change resistance😅it work or not

[@homemade_101]

try

[@hartocahyono2428]

1:09 correct text tjr polarity of LED?

[@11.05.2]

For delay can we can 1000uf capacitor?

[@homemade_101]

try

[@11.05.2]

It's working bro

[@sphelelexaki3434]

Hi urgent help I’m trying to use replicate the same implementation but my circuit is not doing what it’s supposed to, I’m thinking it’s because my power supply is less than the specified +12V, could there be another reason besides that?

[@homemade_101]

are use Active buzzzer or pasive bauzer ?

[@sphelelexaki3434]

Active buzzer

[@TheOrchestra08]

Чудовий ефект і подання. Прохання: хоч на пару секунд показуйте намальовану схему пристрою

Nice brother

[@pratyaksh4283]

I want to make a buzzer with 8 different sounds how tu make ??

[@Time_In_Physical_Form]

@@pratyaksh4283 If you want different sounds I'm pretty sure you need a passive buzzer, those can make sounds with varying frequency. An active buzzer typically only makes a single frequency

[@Great_Things0]

Are you using passive buzzer? Pls tell

[@TheBinklemNetwork]

if you see the "please remove before use" sticker, they are likely active buzzers

[@Robin____854-As]

Bro Ups Mein One time Beep karta hai Wesa Koi Circuit banao plz 🙏😢

[@carloswgramajo]

Para ponerle a la suegra bajo la silla

[@ricardoantoniomartealmonte7434]

la electronica es buena para todo incluso hacer bromas muy buenas jaja .

[@Creative114_]

Good

[@MsLucianomelo]

How many K is the transistor?

[@homemade_101]

100 ohms

[@Steff320i]

You should sell these.

Nice

[@sittinurrabiatulmalik5267]

What is the name of red wire like - 12 and +12input?

[@homemade_101]

circuits wire

[@jorgeponcebianchi6211]

maybe r is 220 ohm insted of2k2

[@homemade_101]

yes

[@ademmergenel]

Ben yaptım Bu yalan çalışmıyor

[@homemade_101]

iyi şanslar

[@raghavsharma5350]

बिल्कुल बेकार

[@homemade_101]

🤔

[@sylvianeta]

-12 e + 12v??? alimentação fora do meu conhecimento convencional. rs

[@homemade_101]

12.9v to 13v
