Arduino Music Player Using Piezo Buzzer

Hey guys, welcome back to Techatronic. You all are familiar with the speakers that generate audible output sound signals. We can play music using various devices such as smartphones, MP3 players, Stereos and many more but can you imagine we can also play music using an Arduino. So in this article, we are going to make an Arduino music player using a piezo buzzer. A piezo buzzer doesn’t have an internal oscillator so you have to provide it the frequency signal with the help of Arduino UNO. If you like this project and want to explore more such projects on Arduino you can check them here. You can also view the Mobile phone-controlled SPY robot using Arduino made by us. First, you have to complete the connections and then upload the code. Your music player starts working when you provide power to the Arduino.

How Does it Work?

The Arduino music player we made is capable of playing different tones in different frequencies. You have to open the Serial monitor screen of your Arduino IDE application. You can found it in the topmost right corner or use the image given below to locate it. When open it will show you a menu and ask for the music you want to listen to. You have to write the corresponding key on your serial monitor and then press enter. The music starts playing.  We have given three different music and you can further add to them by changing the code. We use the switch case in the code for making the choice among all the songs. The tone function is used to produce the sound of the required frequency. You have to specify the pin number of the piezo buzzer and the frequency you want to listen to as the parameters in the tone function. If you want to turn off the piezo buzzer then use noTone function.

Please make the connections according to the given circuit diagram. You can use a breadboard for mounting the piezo buzzer in one place. Connect the GND pin of the piezo buzzer with the GND pin of the Arduino. Attach the positive leg of the piezo buzzer with the digital-11 pin of the Arduino. You can change this pin and connect it to some other digital pin of your choice but make sure that you connect it to the pin marked with a Tilda(~) symbol. These pins are also called the PWM pins of the Arduino in which PWM stands for pulse width modulation.

Code for the Project

NOTE: Please upload the code which is given below to the Arduino as it is.
