Where do we hear buzzing or beeping sounds in our daily lives?

Makes sound to wake you up

alarm clock

Plays a short tune

Doorbell

Makes loud continuous beep

Smoke detector

Objective:

1. Explain what a buzzer is and how it works.

2. Connect a buzzer to an Arduino Uno correctly.

3. Program the Arduino to make the buzzer beep.

4. Run and test your program using Tinkercad.”

5. Relate the use of buzzers in Arduino to real-life applications such as alarms, timers, and notifications.

1- Passive:
Needs a signal to create sound (we program the tone).
2- Active:
Makes sound automatically when powered.

Types of a buzzer

A buzzer is used to create sound or beeps to give audio feedback, alarms, or notifications in an Arduino project.

What is a buzzer

Buzzer:

🔌 Circuit Connection (Buzzer):

💻 Sample Arduino Code:

void setup() {

pinMode(buzzer, OUTPUT);

}

void loop() {

digitalWrite(buzzer, HIGH); // turn buzzer ON

delay(500); // wait 0.5 second

digitalWrite(buzzer, LOW); // turn buzzer OFF

delay(500); // wait 0.5 second

}

💻 Sample Arduino Code:

• pinMode tells Arduino that pin 13 is an output.

• digitalWrite(HIGH) makes sound.

• digitalWrite(LOW) turns it off.

• delay() pauses the program temporarily.

Explaining the code:

void setup() {

pinMode(13, OUTPUT);
}

void loop() {

digitalWrite(buzzer, HIGH); // turn buzzer ON

delay(500); // wait 0.5 second

digitalWrite(buzzer, LOW); // turn buzzer OFF

delay(500); // wait 0.5 second

}

​The Arduino code

Multiple Choice

delay (1000);

1000 in delay is equivalent to how many second?

• 10s

• 2s

• 60s

• 1s

💻 Make a Melody Code:

• pinMode tells Arduino that pin 13 is an output.

• tone(pin, frequency) sets the pitch.

• Higher number = higher sound.

• delay() pauses the program temporarily.

Explaining the code:

void setup() {

pinMode(13, OUTPUT);
}

void loop() {

tone(13, 500); // play note

delay(500);

noTone(13); // stop

delay(500);

}
