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
