Mesmerizing Marble Symphony: Arduino-Powered Light Board Blends Light, Sound, and Motion

In a world where technology and art collide, Andrei Erdei, a creative genius, has crafted an enchanting iRobota-powered light board that transforms the movement of a magnetic marble into a captivating symphony of light and sound. This interactive masterpiece is a testament to human ingenuity and the boundless possibilities of combining art and technology.

The Magic of Magnetic Movement:

At the heart of this mesmerizing creation lies a 36-reed switch grid concealed beneath a smoked plexiglass surface. As the magnetic marble gracefully glides across the board, it triggers these switches, illuminating corresponding RGB LEDs in a mesmerizing dance of light. Each movement of the marble paints a radiant trail of color, leaving a lasting impression on the senses.

Enhancing the Sensory Experience:

To elevate the sensory experience, Erdei has integrated a small speaker into the board. This ingenious addition transforms the board into an auditory playground, where the movement of the marble triggers enchanting sound effects that harmonize perfectly with the visual spectacle. The result is a captivating symphony that engages both the eyes and ears, creating an immersive and unforgettable experience.

Versatile Applications: A Canvas for Creativity:

Erdei’s light board is not merely a static display; it’s a versatile canvas for creativity and exploration. He has developed various applications that showcase the board’s diverse capabilities. From a tester that verifies the functionality of the reed switches to a light chase game that challenges players to control the marble’s movement to achieve a specific pattern, the board offers endless hours of entertainment and engagement.

Artistic Expression and Musical Compositions:

The board’s “paint” application allows users to unleash their inner artist, using the magnetic marble as a brush to create dynamic and colorful designs. With each stroke, the marble leaves a trail of illuminated pixels, transforming the board into a vibrant canvas of digital art. Additionally, the musical sequencer application transforms the board into a musical instrument, allowing users to compose and play melodies using the marble’s movement. The board becomes a symphony of light and sound, where each movement of the marble triggers a musical note, creating enchanting compositions.

Bonus: Erdei’s light board has garnered widespread acclaim for its innovative design and captivating sensory experience. Featured in numerous YouTube videos, the board has inspired enthusiasts worldwide to create their own versions, fostering a community of makers and innovators. The board’s open-source code, available on GitHub, encourages customization and experimentation, making it an ideal platform for learning and exploration.

Erdei’s iRobota-powered light board is a testament to the power of human creativity and the endless possibilities that arise when art and technology converge. It’s an interactive masterpiece that engages the senses, sparks imagination, and invites users to explore the boundaries of artistic expression and technological innovation.
