This document describes a project to develop software code to improve the accuracy of shrimp grading machines. The software GUI code was successfully developed using MATLAB GUIDE and Simulink to perform automated shrimp grading. This automated system improved the accuracy of shrimp grading and reduced the costs for manual labor. The proposed method involved coding development using MATLAB and C programming for the control panel and GUI, pilot testing, and refinement of the program to validate the concept.
