Super Mario Song with Piezo Buzzer on Arduino Uno

Have you ever imagined yourself making a prototype? Then you’re in the right place I guess. Do you know what an Arduino is? Arduino is a microcontroller that helps us build prototypes without any complication and with ease. Our great ideas and dreams could be satisfied in the real life with the help of an Arduino.

Both small and large-scale projects could be easily made with the introduction of Arduino. To all the newcomers, I would recommend you to buy an Arduino starter kit which will mostly have all the items for this project. We all know that during the beginning phase nothing would be simple. In the same scenario, even getting adjusted with Arduino and its connections might be tough. Hopefully, for all the newcomers the project below would be of great use to learn the code and recognize the connections that goes with the Arduino.

The things that we need for this project are one resistor, few jumper wires, a breadboard, an Arduino Uno, and a piezo buzzer.

Moving on to the code, it looks quite complex. Here firstly, we define all the notes properly. Then we initialize all the variables. After this, the two main methods void setup and void loop are set up. Here now, we create a method called void sing with a parameter. One more method called void buzz is created with three parameters.

Over to the connections part, here one connection is done directly to the buzzer and the other one is done indirectly to the buzzer via a resistor. Like others, here we don’t use the positive and negative rails on the breadboard.

After the completion of all the connections as per the circuit diagram given below, you shall proceed to connect your Arduino to your laptop, proceeding with this you can upload the code below using the Arduino IDE software to the Arduino board. Now, you can hear the Super Mario theme song from the Piezo buzzer. To the newcomers again, you disconnect from the PC after uploading the code and just use a source of electricity to power the Arduino and you can enjoy the Super Mario theme song from the piezo buzzer.

Overview – In this project, we will be using a piezo buzzer to play Super Mario Theme song.

Note

1K ohm resistor is used above. Also check whether all pins are connected in proper positions.
