Arduino Uno Tutorial #2 - the Buzzer Song




Hello everyone, as I saw that my first tutorial had been a good gamble, I decided that I'm gonna do a series of Arduino Uno tutorials for you!

Step 1: What You Need

For the buzzer song, you will gonna need :

-Arduino Uno Board ;

-A Buzzer (I don't have a breadboard, so I improvised with jumper wires)
-Usb cable;

-Arduino IDE in your computer;

Step 2: Conect the Board and the Buzzer

Now conect your board in the computer and conect the buzzer like the scheme on the pictures.

If you don´t have a resistor you can conect the buzzer without it, but be cautious with the polarity of the buzzer, so you don't burn it.

Step 3: Upload the Program and Finished!

The last step is too upload the program below to your Arduino IDE and to your board.

#define BUZZER 9
int notes[] = { 524, 588, 660, 699, 785, 881, 989 };

void setup()




void loop()


for (int i = 0; i < 7; i++)


tone(BUZZER, notes[i], 1000); delay(1000);




And you're done.


Step 4: Don't Forget to Follow!

Follow for more Arduino madness!

    It is always important and useful to add plentiful comments to your code to make it easy to understand, especially since you are attempting to provide a tutorial. Nice work.
