Passive Buzzer Module
Introduction
We can use Arduino to make many interactive works of which the most commonly used is acoustic-optic display. All the previous experiment has something to do with LED. However, the circuit in this experiment can produce sound. Normally, the experiment is done with a buzzer or a speaker while buzzer is simpler and easier to use. The buzzer we introduced here is a passive buzzer. It cannot be actuated by itself, but by external pulse frequencies. Different frequencies produce different sounds. We can use Arduino to code the melody of a song, which is actually quite fun and simple.
Specification
- Working voltage: 3.3-5v
- Interface type: digital
- Size: 30*20mm
- Weight: 4g
Connection Diagram
Sample Code
int buzzer=8;//set digital IO pin of the buzzer void setup() { pinMode(buzzer,OUTPUT);// set digital IO pin pattern, OUTPUT to be output } void loop() { unsigned char i,j;//define variable while(1) { for(i=0;i<80;i++)// output a frequency sound { digitalWrite(buzzer,HIGH);// sound delay(1);//delay1ms digitalWrite(buzzer,LOW);//not sound delay(1);//ms delay } for(i=0;i<100;i++)// output a frequency sound { digitalWrite(buzzer,HIGH);// sound digitalWrite(buzzer,LOW);//not sound delay(2);//2ms delay } } }
After downloading the program, buzzer experiment is finished.
