==Hardware Buildup==
*Setup 1：Connect CoreUSB to your PC, open program example, choose the right board and download program via the serial port.

[[File: Noise_alarm_setup_1.jpg|600px|center|thumb]]
*Setup2：Connect Mic to the A0 pin of Sensorhub, buzzer to D6 and crash sensor to D4.

==Software Debugging==
*Build IDE, connect CoreUSB to your PC and download program code.

Code description
*Control pin description
<source lang="cpp">
#define mic_pin A0
#define buzzer_pin 6
#define key_pin 4 </source>

*Sound pre-set value
<source lang="cpp">
#define voice 400
</source>
*If the sound value is greater than the preset value in one second, then the buzzer will give an alarm.
<source lang="cpp">
if (voice_data > voice)
{
if (millis() - time > 1000 )
{
voice_data = analogRead(mic_pin);
if (voice_data > voice)
{
buzzer_speak = true;
i = 200;
}
time = millis();
}
}
</source>
*Touch the key to close the sound.
<source lang="cpp">
if (key_get(key_pin, 0))
{
delay(200);
buzzer_speak = false;
time = millis();
}
</source>

==Result==
If the sound around you exceeds the default value within one second, the alarm will go off. You can press the key and close the sound. (You can also build a beautiful cover with LEGO.)
