1.BC457 2.Buzzer 3.220uf capacitor 4.100ohm resistor 5.22k resistor 6.LED

[@Ormigo111]

it is a 2k resistor not 22k look at the diagram.

[@newbienoob1]

the quation is how the transitor let the current pass without connecting the base 🤗🤗🤗

[@Plasma.Prince]

Perfect pitch for my purpose, but to many pulses per second... would I have to increase the capacitance to slow down the frequency, or the resistance of the 100 Ohm resistor? Perhaps if I increased it to 0.5k?

[@Mitgardxxl]

Why Transistor works without BASE ? I dont understand how that can work. Do you have a idea why it works ? Thank you

[@orlandoromero801]

anda a lavarte el culo....empieza a sonar antes de que conectes la corriente ...????? idiot

[@dorivalgemmi3548]

VERY GOOD WORK MAN VERY GOOD WORK 😮😮😮😮😮😮😮😊😊😊

[@RC-Heli835]

I finally got all the right stuff and got it working! Thanks for sharing!

[@hercooltv]

I made it but the LED is not working and the sound is like a watch tik tik tik it’s not beep sound whyy🙄😓

[@smoothyoffx12]

Your battery health was low

[@dsk1450]

How come this doesn't work for me? I have the exactly set up for the fifth time now but I get NO sound, NO light 😥. I am frustrated now. I even tried to use car battery but nothing changed. @Tech saw Is there anyhow you can assist please?

[@lilbee7492]

I randomly found this video and tried this, everything works well but the buzzer is a little bit quiet in my projects but honestly it's just AWESOME, your project made me make finnaly a blinker circuit thingy while i tried months to do it

[@arunthakare2634]

This circuit works. It should be 12 volts and the current should be above 7 ampere Use Active Mini Buzzer! I am talking about 12 volt circuit

[@Tore_Lund]

Are the LED and the 100 Ohm resistor needed? If you don't need a blinking light?

[@jamessherman4800]

I'm wanting to do this with 3.7v. will it work. And if I use three red leds using resistors for those leds won't change this at all will it?

[@RC-Heli835]

Do you have the part number for the buzzer? I think I have all the other components in stock.

Hello, how are you ? So, I was wondering if this buzzer is passive

[@debbyjansen7427]

@TechSaw Why leave the base of the transistor unconnected?

[@moralesnery]

I'll use this for a DIY car door buzzer, using the car door button to activate or deactivate the circuit. It already provides 12v but I don't know the amperage value. I hope it works, thank you!

[@ultaseedha1699]

ये तो फक फक आवाज करता है 😁😁😄🤪

[@RanaRao_Chandrachur]

This is Esaki's Oscillator

[@abod898]

will to work for passive buzzer ?

[@RC-Heli835]

Love it man!

[@alex33834]

You should explain to users if the buzzer is active or passive. Because with this last does not work. If you post ... explain.

[@will_doherty]

It's an active piezo - a passive piezo won't work. You can see some of the active components in view on the underside of the piezo unit.

[@sumit77194]

Kya hm buzzer ko 3 volt chla ga bta do

[@vijaymareddi4514]

Nice n simple idea thanks for video

[@isaoliveira5216]

Does it work with only 3V?

[@electronic7979]

Good idea 👍

[@pit3835]

what if i will use 12 volt 2 amp adaptor. will this work?

[@wilsonromero8326]

Muchas gracias lo que estaba buscando un zumbador para ac 110voltios 👍

[@SHAKILKHAN-nl9yu]

Can it work on 12v?

[@fulesmackofule]

I just put a similar circut (5V buzzer) with a 330Ohm resistor in the circuit of my motorcycle turn signal and works fine. Not sure though, how long ;)

[@vikasazad08]

Components value please. 1/4watt resistance ya phir 1/2 watt.

[@nagarajunaga5567]

Very, very super

[@JNET_Reloaded]

ur using an active buzzer but what if it was a passive?

[@mrjason9382]

Thanks for shareing

[@RixtronixLAB]

Nice info, thanks for sharing :)

[@Electrothink1]

Is it passive buzzer

[@Ormigo111]

Guys I just made the project and I must say that resistors values aren't correct instead I used a 2K only, the second thing if your project doesn't work try to remove the transistor. I have a PN2222 and to make it work I changed polarity cause it was wrong at the beginning. To say it all even with a 2k and 100ohm resistors mine sounds almost like a continuous beep.

[@eddyadrishan21]

nice sir

[@MAX-ox3xh]

It's an active buzzer. By appearance, the bottom is sealed. You're welcome!

[@agoesgamblong0074]

Buzzer pasif or aktive brother?

[@smartkh9278]

how can get beep sound to longer??

[@NaoPb]

I would think to use a different resistor for the transistor. You could also leave out the transistor to have a constant beep.

[@suranjanghimire659]

Thank you

[@lurkingcorsa10]

input dc or ac?

[@OCIENTISTAcanal]

Se vídeo é bom, Acabou de ganhar mais um escrito 👍

[@Mehedihasan-bc5hu]

I want a diagram of a circuit that contains IPS. Whose job will be to beep 5/6 times when the power goes out. 2 times per second. And when the electricity comes, it will beep once. Please help me with the diagram and what components are needed.

[@nsmadhvendra]

Sir, can you put something else instead of 220 uf capacitor. I put 220uf 16 volt didn't work just buzzer continuous sounding. Please help.

[@Edmorbus]

Thanks for sharing good work

[@safinaaura6097]

Im try,but n't working..something differnt between my country

[@KEVINN651]

Keya kam me ayga yea ?

[@cym247]

Thanx for this nice circuit..I think to use such a circuit in boiling kettle running with 3V or 3.7V...

[@Juansandryas]

how can we modify it to auto off after 5 seconds?

[@rosimarsantiagodelimasantiago]

Muito bom

[@abelolof4809]

500th like, btw awesome channel

[@ianrafaeltoh7679]

can you make a 5v version?

[@amankushwah3435]

Transistor konsa h yai PNP hai Ya NPN mere NPN transistor main kaam nahi kar raha h yai circuit

[@shailmurtaza9082]

why don't you just google that transistor ?

[@leopoldofernandezjr.508]

What is input voltage?

[@codpug]

It shows 12v in the schematic

[@marlonarauz7281]

which R I use to be able to connect that circuit to 110 V?

[@mar1scoz]

Hey! How do you increase the time between beeps?

[@knowledgeseeker9757]

By using different capacitors

[@James-qw7hp]

kzbin.info/www/bejne/npPVpXuBotmNZpI

[@Aikabake]

Components number?

[@granpatriarca3726]

Be sure use an active buzzer otherwise that circuit will not work.

[@comraza01]

Supply ac ya dc

[@kdrbilgin1803]

Dc

[@AnshPratapSingh]

Good project

[@sarkarbrothers7091]

I want more than 3 volt, at the point of LED.like 7.5 volt

[@christostassoulas4146]

Μπορίς να φτιάξεις υχίο

[@Zania3651]

I search this for my motorcycle and I try it.... the buzzer will active when my motorcycle is turned on but the machine are not started.... thanks for sharing!

[@NaoPb]

Connect it between the battery light if you have that. The battery light is on when the engine is not running, because the battery is only charging when the engine is on.

[@deyvisonsilva4175]

pq toda vez que faço isso da errado ele não pega

[@shhamad]

you cant say 2.2K ohms instead of 2K2?

[@rustamabdulhamidov2024]

КРУТО

[@SuperFriend4all]

what was the voltage of you use power

[@AOElectronics.]

Perfect

[@victorgamboa8198]

Este circuito es un oscilador para audio.

[@levitander8133]

Like. 👏👏👏👏👏

[@nikhilpoojari6892]

Supply 12v

[@ritaisabel8665]

Good

[@claudioleme6508]

Não funciona! Estude mais seu circuito e/ou veja sobre a teoria de transistor, ok!

[@andref5069]

Exatamente igual........ NÃO FUNCIONOU!!!!!!

[@khajanekeraaz]

Fake

[@syukrifadholi2267]

No work

[@MMaheshThakur]

Naah uske iye connection ulta krna hoga

[@hariyono4283]

Good idea👍

[@edvandojoao8319]
