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
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?
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?
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.
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!
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 ;)
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.
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!
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.
1.BC457
2.Buzzer
3.220uf capacitor
4.100ohm resistor
5.22k resistor
6.LED
it is a 2k resistor not 22k look at the diagram.
the quation is how the transitor let the current pass without connecting the base 🤗🤗🤗
VERY GOOD WORK MAN VERY GOOD WORK 😮😮😮😮😮😮😮😊😊😊
Why Transistor works without BASE ? I dont understand how that can work. Do you have a idea why it works ? Thank you
anda a lavarte el culo....empieza a sonar antes de que conectes la corriente ...????? idiot
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🙄😓
Your battery health was low

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

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
You should explain to users if the buzzer is active or passive. Because with this last does not work. If you post ... explain.
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.
Love it man!
It's an active buzzer. By appearance, the bottom is sealed. You're welcome!
ये तो फक फक आवाज करता है 😁😁😄🤪
Kya hm buzzer ko 3 volt chla ga bta do
Do you have the part number for the buzzer? I think I have all the other components in stock.

This is Esaki's Oscillator
Are the LED and the 100 Ohm resistor needed? If you don't need a blinking light?

Good idea 👍
what if i will use 12 volt 2 amp adaptor. will this work?
will to work for passive buzzer ?
@TechSaw Why leave the base of the transistor unconnected?
Thank you
Hello, how are you ? So, I was wondering if this buzzer is passive
Does it work with only 3V?
Components value please. 1/4watt resistance ya phir 1/2 watt.
how can get beep sound to longer??
I would think to use a different resistor for the transistor. You could also leave out the transistor to have a constant beep.
nice sir
Can it work on 12v?
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 ;)
Nice n simple idea thanks for video
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?
ur using an active buzzer but what if it was a passive?
Thanks for shareing

Im try,but n't working..something differnt between my country
Is it passive buzzer
input dc or ac?
Very, very super
Keya kam me ayga yea ?
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.
Nice info, thanks for sharing :)
Transistor konsa h yai PNP hai Ya NPN mere NPN transistor main kaam nahi kar raha h yai circuit
why don't you just google that transistor ?
Muito bom
500th like, btw awesome channel
What is input voltage?
It shows 12v in the schematic
Muchas gracias lo que estaba buscando un zumbador para ac 110voltios 👍
Thanx for this nice circuit..I think to use such a circuit in boiling kettle running with 3V or 3.7V...
Buzzer pasif or aktive brother?
how can we modify it to auto off after 5 seconds?
Hey! How do you increase the time between beeps?
By using different capacitors
th-cam.com/video/hbrtHKmtZ00/w-d-xo.html
Be sure use an active buzzer otherwise that circuit will not work.
can you make a 5v version?
which R I use to be able to connect that circuit to 110 V?
Components number?
Thanks for sharing
good work
th-cam.com/video/hbrtHKmtZ00/w-d-xo.html
you cant say 2.2K ohms instead of 2K2?
Μπορίς να φτιάξεις υχίο
Se vídeo é bom,
Acabou de ganhar mais um escrito 👍
I want more than 3 volt, at the point of LED.like 7.5 volt
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!
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.
Supply ac ya dc
Dc
pq toda vez que faço isso da errado ele não pega
КРУТО
what was the voltage of you use power
Este circuito es un oscilador para audio.
Não funciona! Estude mais seu circuito e/ou veja sobre a teoria de transistor, ok!
Like. 👏👏👏👏👏
Good project
Supply 12v
Perfect
Good
Bc548 chalega
Naah uske iye connection ulta krna hoga
Fake
No work
Exatamente igual........ NÃO FUNCIONOU!!!!!!
Good idea👍
no work
