Innovative Design and Experience of Arduino-based Interactive Installation: Seaweed Dance

This paper introduces the innovative design and experience of the Arduino-based interactive installation "Dance of the Seaweed". The installation aims to rekindle people's attention and reflection on the natural environment through the combination of art and technology. The installation utilizes ultrasonic sensors to perceive the distance between the audience and the installation, and adjusts the rotation speed of the seaweed model according to the distance changes, enabling intelligent interaction between the audience and the installation. The article elaborates on key aspects such as the installation's design, hardware setup, programming, and scene construction, and demonstrates the installation's effectiveness in practical applications. Through this installation, audiences can immerse themselves in the beauty of nature, prompting deep thoughts on environmental protection. Additionally, the paper discusses potential improvements and future applications of the installation, such as in art exhibitions and educational outreach, with the goal of bringing more wondrous experiences to people and contributing to environmental protection and science education.
