Sound Detection with Analog Sensor
This project utilizes an analog sensor to detect sound levels.
The sensor's analog output is read by an Arduino board, and the sound intensity is monitored through the Serial Monitor.
If the sound level exceeds a predefined threshold, a message indicating sound detection is printed to the Serial Monitor.
Components Needed
- Arduino Board
- Analog Sound Sensor
- Jumper Wires

Hardware Wiring Explanation:
Analog Sound Sensor:
Connect the analog output of the sound sensor to analog pin A0 on the Arduino.
Ensure proper connections for power (VCC) and ground (GND).
Software (Arduino IDE):
Open the Arduino IDE on your computer.
Write or paste the provided program into the IDE.
Select the correct board and port in the Arduino IDE under the Tools menu.
Upload the program to the Arduino.
Open the serial monitor with a baud rate of 9600.
Start serial communication at a baud rate of 9600 bps to enable communication with the Serial Monitor.
Read Sensor Values:
Continuously read the analog value from the sound sensor using the
Print the sensor value to the Serial Monitor to monitor sound intensity levels.
Detect Sound Threshold:
Set a threshold value for sound detection (e.g., 500).
If the sensor value exceeds this threshold, print a message indicating sound detection to the Serial Monitor.
Adjust Delay:
Add a small delay (e.g., 100 milliseconds) between readings to avoid flooding the Serial Monitor with rapid updates.
