This project integrates three hardware elements—a distance sensor, an OLED display, and a NeoPixel strip - into a smart energy-efficient system. The ultrasonic sensor measures distance to an object, the OLED screen shows the live reading, and the NeoPixel strip responds with color-coded visual feedback. This real-time feedback system supports sustainability by optimizing power usage through minimal hardware and clear communication. It's ideal for smart rooms, object detection, or visual alert systems that prioritize low power consumption.
