Machine gun sound generator Electronic circuit

The machine gun sound generator electronic system sounds very similar to the triggering noisy action of machine gun. This circuit simulates continuous triggering and output obtained can be further amplified with high power speakers. The timing gap between the successive firing can be varied with the help of circuit elementary components. Let’s make our project and understand the working operation and functioning of the circuit.

Principle:

The triggering action of the circuit is the main principle of Electronic machine gun sound generator. Whenever external input trigger is applied to the circuit it oscillated the flow regulation of current and simultaneously send it to the buzzer for amplifying the sound waves. So this is the basic principle of sound wave generator, let’s do it.
