Implemented Sonar constructor to use a single shared pin, added mode flag and helper method for single‑pin measurements. Updated measure() to select the appropriate implementation and added timeout to pulseIn. Integrated periodic sonar updates in the main loop, tracking last update time and toggling a seatBelts flag based on distance thresholds.
