About

Hi, my name is Arjun. I am in sixth grade and I really like playing soccer. In my free time, I enjoy playing video games like Roblox, and I also like Minecraft, even though I do not have the original version. Today, I am going to show you my project using a Raspberry Pi Pico. I will share my screen and explain my code. For this project, I used two RGB LEDs to create different colors and effects. It was really fun to build, and I learned a lot about coding and electronics while working on it.

Music Player

Listen in as Arjun explains how he turned a few lines of code into real-world music and colorful lights, transforming a simple idea into an unforgettable gift.


How Arjun's Music Maker Works:


The Brain: He used a Raspberry Pi Pico to control the entire project.

The Sound: A small buzzer plays the Happy Birthday melody, reading specific music notes right from his code.

The Lights: An RGB LED flashes millions of color combinations while the music plays.

The Controls: A simple slide switch lets him change the light patterns on the fly.


Learning Through Trial and Error:

Arjun didn't get it right on the very first try. He spent over two hours testing, fixing, and tweaking his code- testing the song 4 times and the light patterns up to 8 times! His dedication shows exactly how hands-on tech projects teach kids patience and resilience.


Be sure to stick around to the end of the episode to hear a beautiful update from Arjun's mom. She shares how his journey with Moonpreneur completely shifte
