Analog Sound Sensor is typically used in detecting the loudness in ambient, and the controller of Arduino could collect its output signal by imitating the input interface. The sensor contains a condenser microphone. The sound will change capacitance value. Then, the voltage value is changed. And LM358 sensor chip can enhance the signal. The enlargement ratio is 50 times. You may use the sensor to make funny interactive projects of Arduino or Scratch.
