Arduino, Automation, Servomotor, Electric System The development of an electrical system for sorting boxes by size represents a significant advancement in mechanical automation, aimed at optimizing sorting efficiency and reducing manual labor. This system integrates modern sensors, controllers, and actuators to enhance sorting accuracy while minimizing errors. The proposed framework addresses key challenges in supply chain management by incorporating transport systems for effective box movement, box detection sensors, and a laser or infrared measurement system for precise size determination. The main control unit, an Arduino microcontroller, processes sensor data to guide the sorting process. The sorting mechanism employs servo motors, solenoids, or pneumatic cylinders to direct boxes into designated chutes. A Human-Machine Interface (HMI) facilitates real-time monitoring, and a robust communication system ensures seamless data exchange for smooth operation. Safety features, including emergency management tools and security sensors, enhance the system's reliability. Thorough testing confirms its functionality under diverse conditions, optimizing speed, compatibility, and sorting precision. This system significantly improves supply chain efficiency, reduces human intervention, and enhances operational coordination.
