This study aimed to develop an Arduino-Uno-based automated coin-counting machine using applied experimental research design.The device aims to sort and count coins easily.The system offers advantages like precision, speed, efficiency, and reliability, saving organizations time and reducing errors in cash handling.The researchers used an experimental design to create and assess the system, using components like the Arduino Uno, an IR sensor, a breadboard, and an alphanumeric LCD.Data was collected through an evaluation checklist from 21 participants who observed the system during a trial.The device underwent repeated evaluations to confirm its accuracy and durability, establishing it as a certified coin-segregating device.These coin counters and sorters have several advantages: precision, speed, efficiency, and reliability.It will help organizations save time and eliminate mistakes by automating the counting and sorting of coins and the reliability of their cash handling systems.The findings of this study reveal that the participants strongly agree that the device is effective in terms of its detection time, accuracy, and convenience.Moreover, the device's effectiveness is influenced by the type of coins and not by their texture.This suggests that specific coin characteristics may challenge the system's performance and accuracy.Future researchers may consider existing sorting methods, develop efficient sensor data analysis programs, provide thorough documentation of processes, integrate with other systems like money changers or financial systems, and potentially release the system as open-source to foster collaboration within the Arduino community.
