Microduino-Buzzer is passive just like a magnetic speaker. It needs voltage with different frequency and thus can make sound accordingly. The sound becomes louder when the frequency gets higher.

==Feature==
*Controllable sound frequency (eg: You can achieve the effect of piano spectrum with it. )
*Small size and beautiful

==Specification==
*Operation voltage—3.3V~5V;
*1.27mm pitch and 4Pin interface;

==Document==

*Schematic：'''[[File: Microduino_ Buzzer.Zip]]'''

==Development==
It can be used to make various kinds of sound through the buzzer.
==Application==
*Hardware Needed: [[Microduino-Core]], [[Microduino-USBTTL]], [[Microduino-Sensorhub]], several dupont lines and USB cable;
*Software:
**Make sure you did build Microduino development envrionment or you need to refer to: [[Microduino Getting start]]
*Program
<source lang="cpp">
#define buzzer_pin 6
void setup()
{
pinMode(buzzer_pin,OUTPUT);
}

void loop()
{
for(int i=200;i<=800;i++) //Increase the frequency from 200HZ to 800HZ circularly.
{
tone(buzzer_pin,i); //Output frequency in the port.

delay(5); //The frequency lasts for 5ms.
}
delay(1000); //The highest frequency lasts for 1s.
for(int i=800;i>=200;i--)
{
tone(buzzer_pin,i);
delay(10); //The frequency lasts 10ms.
}
}
</source>
*Stack all the modules and then connect the interface on the back of BUZZER to the D6 digital port of Sensorhub.

*Open IDE, copy the program to IDE, choose the right board, compile and download.
*You can hear the alarm after download.
