A New Way To See Music - Sound Waves & Lasers

The video explores the concept of visualizing sound waves using a laser and various electronic components. It begins with an introduction to sound waves and the challenge of observing them. The instructor then demonstrates how to set up an Arduino, speaker, and amplifier to generate sound. The video covers the assembly of the setup, including the use of a potentiometer for pitch control. It also explains the differences between mono and stereo audio jacks. Finally, the completed setup is tested, showing how sound waves can be visualized through a laser reflecting off a vibrating mirror.
