Robot Vaccum Circuit

This Arduino-based circuit integrates multiple sensors and actuators to create a comprehensive robot vacuum control system. The circuit combines ultrasonic distance sensing, force detection, obstacle avoidance, and motion detection to enable intelligent navigation and cleaning functionality.

The system uses a ULN2003 motor driver to control a stepper motor for precise movement, while various sensors provide real-time feedback about the environment. The piezoelectric buzzer provides audio feedback for different system states, making this a complete embedded system prototype for autonomous cleaning applications.
