Passive Buzzer Module for Arduino

How to connect the passive buzzer module to Arduino:

1. Connect the positive module terminal (usually marked red) to the Arduino 5 V output.
2. Connect the negative module terminal (usually marked black) to Arduino GND.
3. Connect the signal wire (usually marked yellow) to an Arduino digital output.

Arduino code:

// Definujte pin, ku ktorému je pripojený Buzzer Modul
const int buzzerPin = 9;

void setup() {
// Nastavený pin ako výstup
pinMode(buzzerPin, OUTPUT);
}

void loop() {
// Zapnutie Buzzer Modulu na 1 sekundu
digitalWrite(buzzerPin, HIGH);
delay(1000);

// Vypnutie Buzzer Modulu na 1 sekundu
digitalWrite(buzzerPin, LOW);
delay(1000);
}

This code turns the buzzer module on and off at one-second intervals. Modify it as needed.

Passive buzzer modules can be used in projects including:

• Alarms
• Timers
• Toys
• Medical equipment
• Industrial applications
• Automotive applications
