I designed and built an interactive LED installation that transforms an ordinary stairwell into a dynamic, responsive environment. Using an Arduino Express board with custom programming, the system detects environmental sounds and responds with synchronized light patterns and audio feedback. The installation features strategically placed LED strips along the floor panels that create an upward-flowing light animation when triggered by door closures or ambient noise. The programming includes threshold detection algorithms that filter out background noise while responding to specific acoustic signatures of the space. This project showcases my skills in embedded systems programming, hardware integration, and creating site-specific interactive experiences that blend technology with environmental design.
The system uses an Arduino Express microcontroller programmed with custom C++ code to monitor sound levels through built-in microphones. When sound exceeds the calibrated threshold, the system triggers a sequence of LED animations and plays synchronized audio clips. The LED strips are controlled through digital output pins, creating smooth color transitions and movement patterns that simulate light flowing upward through the stairwell.
