Objective:

         To activate the Buzzer in order to make sound for alert

Components Required

• Arduino Uno
• Piezo Electric Buzzer

 Connection Diagram

Program

int Buzzpin=13;

void setup()

{

pinMode(Buzzpin, OUTPUT);

}

void loop()

{

digitalWrite(Buzzpin, HIGH);

delay(1000);

digitalWrite(Buzzpin, LOW);

delay(1000);

}

Working

         The Program Activates the Buzzer to ON by supplying HIGH voltage to it and making it OFF by supplying LOW voltage to it. This process repeatedly happens to make the Buzzer alternately making the sound

Output

The Buzzer alternately making the sound
