QB010/QB077 P-Buzzer Module

1.Product Introduction

Buzzer module is an integrated structure of sound electronic components, using DC power supply, widely used in toys, alarms and other electronic products. Buzzer is divided into passive buzzer and active buzzer; There is no shock source inside the passive buzzer, and it needs to be driven by 2K~5K square wave. Passive buzzer can freely control the output sound frequency, and can be programmed to write different scales and duration time to synthesize a beautiful melody of music.

13void setup(){
14  for (int x = 0; x < length0; x++) {
15    tone(buzzerPin, tune0[x]);
16    delay(500 * durt0[x]);
17    noTone(buzzerPin);
18    delay(30);
19  }
20}
21void loop(){
