Thank you for the explanation! I was wondering why the buzzer I was using was making an awfully sounding tone, turns out the kit provided two identical-looking buzzers - I was using the active one.

My first project is going to be an automatic dog whistle for while I'm away from my apartments, this video is a great helping start gonna watch all the previous videos now!

To whoever wants to give this a try, you may need to reformat it in the Arduino IDE, though.

// Pin where the speaker/buzzer is connected
const int speakerPin = 13;

// Define the notes of the song (in Hz)
const int C4 = 261;
const int D4 = 294;
const int E4 = 329;
const int F4 = 349;
const int G4 = 392;
const int A4 = 440;
const int B4 = 466;
const int C5 = 523;

void setup() {
// No setup needed for this example
pinMode(speakerPin, OUTPUT);
}

void loop() {
// Twinkle Twinkle Little Star melody
tone(speakerPin, C4, 400); // C4 for 400ms
delay(400); // Wait for the note to finish

tone(speakerPin, C4, 400);
delay(400);

tone(speakerPin, G4, 400);
delay(400);

tone(speakerPin, G4, 400);
delay(400);

tone(speakerPin, A4, 400);
delay(400);

tone(speakerPin, A4, 400);
delay(400);

tone(speakerPin, G4, 800); // G4 for 800ms (longer duration)
delay(800);

// Repeat the melody (you can modify for more or fewer repetitions)
tone(speakerPin, F4, 400);
delay(400);

tone(speakerPin, F4, 400);
delay(400);

tone(speakerPin, E4, 400);
delay(400);

tone(speakerPin, E4, 400);
delay(400);

tone(speakerPin, D4, 400);
delay(400);

tone(speakerPin, D4, 400);
delay(400);

tone(speakerPin, C4, 400);
delay(400);

// Wait before repeating the song
delay(1000);
}

ty sir, short, useful, well explained

Nice job man 👍.. btw sorry if i ask .. but is there any way how to make that buzzer wireless plus make the distance more longer like around 500 meters to 1km ? and when you press the button it will make the tone .. keep up the goodwork man .. big thanks

Could you please send the code?? It would be a huge help😊

Hello, mine just produces a loud buzzing sound regardless of the code. any idea why?

[omvatisharma]

Can you please give me the code for both active and passive buzzer please

[SocratesFil]

Thanks for the tutorial! Is it possible that a buzzer can in some way damage the output pin of the Arduino, perhaps drawing too much current or by backEMF of some kind? Is it completely safe to use them directly no matter which size of buzzer we deal with? Also the loudness of the sound is pretty low, is there any way to increase it?

Tips for tmb12A05? Can't seem to get it to buzz

[stevhandingwall]

I got error in code low was not declared in scope

where is the sketch, i need the skectch please thank you bye sorry
