Mozart Project

Mozart Project

Music Project

Mozart, the iconic composer of the classical period, still continues to impress musicians and fans worldwide. In this project, we’ll explore how to recreate one of Mozart’s famous compositions using the PicoBricks platform. PicoBricks is the perfect choice for music enthusiasts and tech lovers. Our project focuses on recreating Mozart’s masterpiece using PicoBricks. We’ve transformed a chosen piece into a cute little snippet, turning it into a captivating music experience. With just a few lines of code, a bell, and a bit of creativity, we can bring Mozart’s music to life in a completely new way.

Details and Algorithm

So, first things first, we gotta set up some constants for our project. We’ll give a pin the name BUZZER_PIN, and we’ll define frequencies for different music notes like A5, B5, C5, D5, E5, and G5 as NOTE_A5, NOTE_B5, NOTE_C5, NOTE_D5, NOTE_E5, and NOTE_G5, respectively. 

Next up, we’re gonna make an array called mozartSongMelody, which will hold all the notes in our melody. We’ll also make another array called mozartTempo to set how long each note should play. In the setup function, we’ll make sure BUZZER_PIN is set as an output so we can actually hear the sound. 

Now, let’s get to the fun part: the loop function. We’ll use the sizeof function to figure out how many notes are in our melody. Then, we’ll go through each note in the mozartTempo array. 

Inside the loop, we’ll calculate how long each note should play based on the tempo. Using that duration, we’ll use the tone function to play the note on the buzzer. We’ll also calculate a pause duration between notes to give it some rhythm and musicality. Once a note’s done playing, we’ll use noTone to stop the sound.

And that’s all there is to it! This algorithm and code let you play a beautiful Mozart melody using a buzzer. With PicoBricks, MicroPython, and Arduino, you can try out different melodies and make your own melody projects. So go ahead and dive into these simple but super fun melody projects and explore the world of sound & sound project!
