◦ Project
This Arduino-based circuit integrates multiple sensors and actuators into 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 behavior.
A ULN2003 motor driver controls a stepper motor for precise movement, while the sensors provide real-time environmental feedback. A piezoelectric buzzer signals different system states — a complete embedded prototype for autonomous cleaning applications.
