Ticking Bomb Sound Circuit using 555 IC

This circuit sound just like a ticking bomb.It utilizes the astable mode of 555 IC and produces ticks that are similar to a time bomb ticking.

Components Used:

1.one 555 IC
2.two 10uF Electrolytic Capacitor
3.one 47K ohm resistor
4.one 6-12 V power supply
5.one 8Ohm speaker

STEPS :
1.Place 555 IC on BreadBoard.
2.Connect pin 1 to ground(-ve terminal of battery)
3.Connect pin 2 with pin 6.
4.Connect pin 4 with pin 8.
5.Connect pin 8 with VCC (+ve terminal of battery)
6.Connect 47K resistor with one leg at pin 2 and another at pin 3.
7.Connect 10uF cap with longer leg(+ve ) to pin 2 and shorter leg(-ve ) to ground.
8.Now connect another 10uF cap with longer leg to pin 3 and shorter leg to a terminal of speaker,
and connect another terminal of speaker to ground. 
9.leave pin 5,7 as there is no use of them in this circuit.
10.Turn on Power to circuit and Enjoy the effect.

 

(NOTE - I didnt have 47K so i tested the circuit by putting series resistances equal to 40K)
