Technology can make our lives better, but now we are in a situation where we control everything through one thing-the screen.

Although the screen is very intuitive and convenient, it is too boring to deal with glass every day. We need something different, so my goal is to design a physical experience that you can interact with when you listen to music.

This is the plan that my graduation project was abandoned, but I still want to make it, so I completed it during the postgraduate preparation after graduation, and it took me half a year. In order to realize the function in this 6 cubic centimeter square body, I learned the circuit design from scratch and used the Arduino platform. I know that the shape, structure, function and circuit layout need to be improved, but this should be regarded as the closest thing to the "product" that I have independently completed, and I still like it.
