Example Code to Control a Buzzer Alarm

Here’s an example of how to use a 95 dB buzzer with an Arduino to create a basic alarm system. The code below turns the buzzer on for a specified duration.

Required Components:

• 1 x Arduino board (e.g., Arduino Uno)
• 1 x 95 dB buzzer
• 1 x 220-ohm resistor (optional for limiting current)
• Jumper wires
• Breadboard (optional)

Circuit Diagram:

• Buzzer Positive Terminal: Connect to a digital pin on the Arduino (for example, pin 9)
• Buzzer Negative Terminal: Connect to the Arduino GND
• If using a resistor: Connect it in series with the buzzer.

Arduino Code:

Copy// Define the pin for the buzzer
const int buzzerPin = 9; 

// Duration the alarm will sound (in milliseconds)
const int alarmDuration = 1000; // 1 second

void setup() {
  // Set the buzzer pin as an output
  pinMode(buzzerPin, OUTPUT);
}

void loop() {
  // Turn the buzzer on
  digitalWrite(buzzerPin, HIGH);
  
  // Wait for the duration of the alarm
  delay(alarmDuration);
  
  // Turn the buzzer off
  digitalWrite(buzzerPin, LOW);
  
  // Wait for a while before restarting (can adjust as needed)
  delay(2000); // Wait for 2 seconds before sounding again
}

Explanation of the Code:

• The buzzer is connected to digital pin 9 of the Arduino.
• The setup() function initializes the buzzer pin as an output.
• In the loop(), the buzzer is turned on for a specified duration (alarmDuration) and then turned off. The loop will keep repeating, sounding the buzzer every 2 seconds.

Conclusion

This implementation showcases how a 95 dB buzzer alarm can be effectively used in conjunction with an Arduino microcontroller. The buzzer can be integrated into various systems and applications, providing a reliable alert system for a wide range of needs. Always consult the specific datasheet for your buzzer model for precise specifications and connection details.
