Hello Friends,

I want to build an alarm circuit which can generate sound like police (High and low) and second a plain beep sound. And a switch which can toggle this sound as required.

So i want two sounds :

1)police
2)High beep

I have following things in my lab :

IC : CD4060 ,CD4063.
TRANSISTORS : BC547 ,BC337 ,BC558 [PNP]..
SPEAKER : 8 ohms

And I have complete resistor and capacitor packages.

I want to run on 8v or 12v dc power supply ?

Thanks in advance !

Please provide me the schematics as I deserve !

As you deserve? Oh yes sir, let me get right on it.

Try a Google of two tone warbler circuit. Consider circuits like these.

Many people in this forum have bent over backwards trying to help you with what has become an unending list of request. Maybe it is about time you started to learn on your own? You do not deserve anything. You will take what you get and like it.

Why doesn't Yusuf use Google SEARCH for information and Google IMAGES for schematics like this?
