This document describes the design and implementation of an automatic medicine reminder system using an Arduino microcontroller. The system uses an Arduino with an EEPROM and buzzer to provide reminders for medication schedules entered through a keypad interface. When the scheduled time arrives, the system sounds an alert and displays the medication name on an LCD screen. The system is intended to help patients adhere to medication schedules by providing reminders. It provides a low-effort solution using easily programmable hardware and could be useful for patients managing multiple medications or busy schedules.
