It measures sound using Arduino and turns on the red light of the RGB LED if the sound is loud. At the same time, it measures distance with HC$-$SR$04$ and detects with the motion sensor with HC$-$SR$501($PIR$).$ If there is an object nearby, it prints "there is someone nearby $-$ loud sound" on the LCD display. If the motion and distance sensor does not detect anything, it only prints "loud sound", if the sound is low, it turns on the blue or green light of the RGB LED, it measures the distance with HC$-$SR$04,$ and by detecting the motion sensor with HC$-$SR$501($PIR$),$ if there is an object nearby and the LED Let's develop a program that prints "sound at normal level" on the screen, but if there is no movement or object, it prints "Safe". It will measure sound with the Sound Sensor Card $-$ Microphone Sensor.

If loud noise and motion are detected with the microphone sensor and HC$-$SR$04$ and HC$-$SR$501$;

Turn on the red light of the RGB LED,

Print $$There is someone nearby $-$ Loud voice$$ on the LCD display,

If there is only loud sound, no movement detected;

Turn on the RGB red light,

Print $$Loud volume only$$ on the LCD display.

If low noise and motion are detected with the microphone sensor and HC$-$SR$04$ and HC$-$SR$501$;

Turn on the blue light of the RGB LED

Print $$Low sound $-$ motion detected$$ on the LCD display.

If no motion is detected and the sound level is not high;

Turn on the green light of the RGB LED

Print $$secure$$ on the LCD display.
