WORKING

Welcome to the Arduino Based Project which consists of Small sound sensor module and its basic functionality is being described here. The microphone sound sensor, as the name says, detects sound. It gives the approximate measurement of how loud a sound is.

After uploading the code, you can clap next to the sensor. If the LED is not lighting up, then you need to change the sensor sensitivity by rotating the potentiometer. Also, you can also adjust the sensitivity so that the LED follows the beat of certain music. Thus, add more LEDs for a more spectacular effect.
