Bhai best😁 gajab👍👌
Very nice sir.
Supper its working brooo💪💪💪😍😍😍❤❤❤
circuits knowledge: ✅️
siren knowledge: ❌️
can you suggest which value pots I can use to build a similar circuit, but with adjustable pitch and siren speed? Thanks.
Hello, I have built your circuit and am now looking at some easy modifications I have added a pot instead of fixed resistor, but I really need a lower pitch, can you suggest how I can achieve this? Thanks.
Can I use lower ohm speaker? What about 4 ohm?
Bhut acha karte ho jo sp pahle sabhi component ko show kar dete ho
Um super like
What if I want to add a trimpot to make the sound slower?
Connect 9v?
I’m having some problems because it doesn’t start at first only it I touch pin 6 with something and if connect pins for different tone it doesn’t change tone only one tone.
Um 3561 ic bazzar se mil nahi raha old kis board se nikal sakte hai
Bhai Mai jarur banauga cycle ke horn ke liye
Kis battery se chlega
Mujhe smj nhi araha zenner diode ki powe supply ke parrel lgani haa positive ke yaa negative
3volt battery se chalega.
Parallel ka matlab anode positive ke sath or cathode negative se joint karna hai.
Super! How to make a sound from the chip Sonar?
Bhai 3.1v zener diabote ko kaise lagaye
I made example of your circuit but it didn't work but as for me I made it with IC JRC4558
Why it didn't work? Troubleshoot it. If not work then learn electronic again.
3 volt cell watch wale ya charging wale 3 volt cell ya dono se chl skte h
Dono se.
Ok
Now put them on separate circuits and build an amplifier
Use any speaker or ,,only use 8ohm this speaker
Max 8 ohm and minimum any?
Bhai um 3561 nahi mil raha, koi link bheje..
12 watts operate avuthudha
Bhai 3 volt ca speaker Laga to chalega
Chalega
Iski awaaz tej khese karein
Bhai Kitne watt de rha h
Kha kis bajar se ic milegi Mera 60 ruppee bekar ho gaya
Bhai yeh ic to mil ee nai rha iski koi easy milne wali replacement ha to bta do
No replacement for this ic you can buy from this link. m.alibaba.com/product/60823509002/UM3561-UM3561A-DIP-8-straight-plug.html?spm=a2706.7843667.0.0.36d81ceehdiFdB&prepage1=enalibaba%3A%2F%2FoneSight%3Fbiz%3Dseo%26keyword%3Dum3561%20ic
UM 3561 IC එක කොහෙන්ද ගන්න පුළුවන් කොළඹ?.
English
Brother can i use 12v battery ?
Yes but you can add one 3. 1v zener diode parallel to power supply, because ic need only 3 v. Direct 12v can damage the ic.
@@Erpankaj925 brother please tell me ic price
50 to 70 rs/-
Bro dont forget to subscribe my channel
@@Erpankaj925 ok thanks
Not working
Change ic
Fak
Come to me and i will teach you how to make this.
Sar mena try kya ha Lakin nhi chala
Check circuit diagram properly and then try again.
