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 !
