LASER AUDIO DISPLAY

In Chapter 12, you learned the basics of the Arduino, which is perfect for interfacing with low-level electronic devices. In this project, you’ll leverage the Arduino to build hardware to produce interesting laser patterns from audio signals. This time, Python will do more of the heavy lifting. In addition to handling serial communications, it will perform computations based on real-time audio data and use that data to adjust the motors in a laser display rig.

For these purposes, think of a laser as an intense beam of light that remains focused in a tiny point, even when projected over a large distance. This focus is possible ...
