EXPANDED TECHNICAL DETAILS

Multi-Spectral Light Synthesis

A foundational project exploring specialized LED modules capable of high-speed color cycling and PWM modulation.

  • Sequential Chromatic Cycling: The Arduino manages a specialized 7-color flash LED or a cluster of RGB LEDs. Using a simple timing loop, the firmware cycles through primary and secondary color combinations.
  • PWM Diffusion Pattern: (Advanced version) Utilizes Pulse Width Modulation on independent R/G/B channels to create custom "Breathing" or "Strobe" effects, demonstrating the basics of digital lighting control.
