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

Circuit Diagram:

Procedure:

1. Place 555 Timer IC on the bread board with its notch facing up as shown in the figure below

2. Connect pin 1 of the IC to the negative rail of the bread board, and pin 2 and 6

3. Similarly connect pin 4 and 8 as shown in the figure below

4. Now connect 33k Ohm resistor between pin 6 and pin 3 of the 555 Timer IC

5. Now place 10uF Capacitor on the bread board as per the circuit diagram

6. Place the Transistor on the bread board with its collector pin connected to the Pin 8 of the IC and emitter pin to the positive rail of the breadboard

7. Now place 10uF Capacitor on the bread board with its positive terminal to the base of the transistor.

8. Similarly connect 10uF Capacitor with its negative terminal connected to the pin 3 of the IC

9. Now place 100k Resistor between the base of the transistor and negative rail of the bread board

10. Now place 100uF Capacitor on the bread board with its positive terminal connected to the emitter and negative terminal to the collector pin

11. Now Connect a speaker preferably of 8 Ohm between the positive rail and common point of 10uF Capacitor.

12. Finally Connect the power supply and our machine gun starts producing the sound similar to the machine gun

13. And to the maintain the timing for ON and OFF transition a momentary push button is added to the circuit as shown below

14. With the help of this we can easily control our electromic machine gun sound generator

Whenever the trigger is applied to the circuit externally, the circuit starts producing and emitted the sound similar to the machine gun generator. Do the project and get the best practical knowledge and hands on experience.
