Abstract: This project was to design and implement a Medicine Time Reminder System, aimed at helping patients remember to take their medications on time. The system was designed with a microcontroller as the central processing unit, which regulated and controlled all the system's activities. The microcontroller receives input from a Real-Time Clock module, then compared to the pre-set alarm time stored in its memory, The alarm is triggered when the two times align, causing the system to vibrate and initiate calls to the designated phone numbers. In the implementation process, a 3-by-4 keypad was connected to the microcontroller, allowing patients to set the alarm time and phone numbers. The OLED display was connected to the microcontroller via an I2C protocol and displayed system status, time, date, and other data. A GSM module was connected to the microcontroller via a serial communication protocol, allowing the system to make calls. A buzzer and vibrator were connected to the microcontroller through a BC547 transistor, providing sound and vibration notifications. The system was tested with 110 patients aged 17 years and above. The assessment results showed that the system was highly effective in ensuring the patients took their medications on time. Eighty-four percent of patients reported that the system effectively reminded them to take their medication at the right time. The medicine time reminder system utilizing sound, vibrators, and a GSM module offers a comprehensive solution for medication adherence. By combining auditory and tactile cues and incorporating Phone calls, this system improves the chances of timely medication intake and helps individuals stay on track with their prescribed dosage schedules.
