Echoes of Light
Arduino UNO R4 WiFi
Echoes of Light boasts several interactive features. Sound-reactive lighting changes LED patterns based on the intensity and frequency of ambient sounds. Motion interaction allows the installation to adjust light displays in response to viewer movements detected by PIR sensors. Distance-based effects alter colors and patterns according to how close or far viewers are, using ultrasonic sensors. Finally, dynamic reflections are created by servo motors moving reflective surfaces, resulting in ever-changing light reflections and refractions.
