This study presents the Microcontroller-Based Seashell Crasher-Pulverizer Machine, a microcontroller operated machine designed to crush and pulverize discarded seashells into fine particles. The machine utilizes a motorized crushing mechanism controlled by a microcontroller for precise and efficient operation. Performance tests evaluated the machine's effectiveness in terms throughput capacity, production efficiency, and facilitate versatility. The pulverized seashells were analyzed for potential applications in agriculture, and animal feeds, showcasing their value as sustainable raw materials. Results demonstrate that the seashell crasher pulverizer provides a cost-effective and environmentally friendly solution for managing seashell waste while contributing to resource optimization. This research highlights the potential for simple yet impactful technologies to promote sustainability and waste utilization in various industries.enThesis
