Wailing Siren Circuit on Breadboard | 555 Timer Project #10
HTML-код
- Опубликовано: 10 сен 2024
- A tutorial on how to make a wailing siren circuit using 555 timer IC on a breadboard. Explanation of how this circuit works is also included in the video.
This circuit can be triggered by pressing a push button switch and it produces a tone with increasing intensity for as long as push button is pressed. After the push button is released, the intensity of siren sound gradually reduces to zero.

Components Required:
* 555 timer IC
* 8 Ohm Speaker
* Transistors: 1 BC547, 1 BC557
* Momentary Push Button Switch
* Capacitors: 10nF, 100uF
* Resistors: 39R, 22K, 33K, 100K, 2 * 220K
* Breadboard
* Few Breadboard Connectors
* (5-9)V of Power Supply

This is best channel I ever came across ❤️
Very nice project with excellent explanation! A project with a microcontroller seems me very interesting to.
Yes, I have a few videos already recorded. Will plan videos on Arduino/Microcontrollers after finishing them.
Great video! I love how you use stop motion and the texts for your video. I look forward to your future videos,have fun.
Thank you. I use import all the frames to premiere pro, add them to the timeline and compress the total time. Adobe After effects for any graphics.
I did the circuit as same but I get siren sound when I connect power supply 😢not when I press button
Good job 👍👍👍
Nice project. I like it
Great video sir
you mention 1k across base of 457 and pin three where as in description you mention 100k.
Your explanations were too good 👏... Can you please do a video on music reactive led using Condenser mic
Thank you. I've noted down your suggestion. Will make a video on it as soon as the 555 timer video series is done.
Good work
Greetings elonics, is there some way I can connect an LED to the circuit so that when the siren is on and when the siren stops the LED closes? If yes then can you tell me how to do that? Thank you very much
Greetings. Yes, that is possible. You can connect LED directly at the output of 555 IC (Pin-3) via a suitable resistor (~330R)
You didn't show 1k resistor in component list
you forgot to mention the transistor bc 547 & bc 557, and also you forgot to mention 1 K resistor in description.
Thank you :) I've updated the description
Sir how you make many circuit you have course
Sir awesome project please start making project on microcontroller..
Yes, I agree.
Yes, But I have a few videos already recorded. Will plan videos on Arduino/Microcontrollers after finishing them.
@@elonics thank u sir, will be waiting. 😇
Hello sir excellent project for a student like me may I know how much the components cost
Hello sir , how much profit do you make from your channel per month ?
You have not added the 1k resistor to the component list (I must wait 3 mores days just for that part now!!). Thanks!
Hi, I did not use a 1K resistor anywhere in the circuit build. Please have a look at the circuit diagram here: elonics.org/wailing-siren-circuit-using-555-ic/
@@elonics you did use 1k watch 1:46
@@mohamedhasifkh4822 on the diagram it shows as a 220k resistor, I think that he mispoke. A 220k makes more sense as it drives the NPN (BC547) which only needs a small signal at the base
Can u tell how many ohms and watts is the speaker used
🙏
I have used an 8 Ohm 0.5 Watt speaker
@@elonics tenks sir
Hoping more for these type of projects
@@venugopal701 Sure
@@elonics sir i have a request
Sir will u make arduino related projects
That's the plan. But unfortunately I was not able to allocate sufficient time.
