In modern manufacturing, sorting machines have become an essential component to produce high- quality products. Automated sorting machines have become popular due to their ability to perform the sorting process quickly, accurately, and efficiently, reducing manual labor and improving overall efficiency. This research paper presents the design and development of an automated color and metal sorting machine using relays, Arduino, and a conveyor belt system. The machine uses sensors, cameras, and algorithms to sort materials based on their color and metal composition. The sorting process is fast, accurate, and efficient, reducing manual labor increasing productivity.
