Belt [new]: Build Flash

1. Introduction: What is a Flash Belt? A Flash Belt is a wearable electronic device—typically worn around the waist—that contains a series of high-brightness LEDs programmed to light up in sequence, flash in patterns, or react to sound/motion. Popularized by rave culture, cyberpunk fashion, theatrical performances, and safety gear for nighttime runners, the flash belt combines fashion with functional electronics.
