<![CDATA[Elderly compliance in taking medication on time is a crucial factor in the success of long-term therapy, but cognitive decline often causes them to forget medication schedules, increasing the risk of complications. This study aims to design an Arduino-based medication reminder tool with voice output without an internet connection or smartphone. The method used is quantitative with a prototyping approach, including needs analysis, design, assembly, and system testing. The tool integrates Arduino Uno, RTC DS3231, 16x2 I2C LCD, 4x4 keypad, DFPlayer Mini, and speaker. Functional testing shows the tool is able to sound an alarm and display medication information on time with three repetitions of notifications. A questionnaire to three elderly respondents produced an average score of 4.30 or 85.9% in the Very Good category. This tool is proven to help elderly people remember medication schedules and types independently without relying on others or the internet.]]>
