Introduction
A piezoelectric buzzer is an audio signalling device. A sample piezoelectric buzzer is shown below.
Typical uses include alarm devices, timers and confirmation of user input such as a mouse click or keystroke.
Adjustable coupling
- Sensors Pack for Arduino [KIT_SENPACK]
Example Project
Hardware Preparation
- Arduino Duemilanove or Compatible Arduino Controller (1 unit)
- Buzzer (1 unit)
- Prototyping Shield (1 unit)
- Mini Breadboard (1 unit)
- Jumper Cables (2 units)
Programming
<syntaxhighlight lang="c"> //For Arduino Start kit //Compatible with all Arduino version // //
int buzzer=8;//Connect the buzz positive Pin to Digital Pin 8 void setup() {
pinMode(buzzer,OUTPUT);//Set Pin Mode as output
} void loop() {
unsigned char i,j;
while(1)
{
for(i=0;i<80;i++) //Sound effect 1
{
digitalWrite(buzzer,HIGH);//Make some sound
delay(1);//Delay 1ms
digitalWrite(buzzer,LOW);//Be quiet
delay(1);//Delay 1ms
}
for(i=0;i<100;i++) //Sound effect 2
{
digitalWrite(buzzer,HIGH);//Make some sound
delay(2);//Delay 2ms
digitalWrite(buzzer,LOW);//Be quiet
delay(2);//Delay 2ms
}
}
} </syntaxhighlight>
