Embedded C project using the LPC2148 ARM7 microcontroller to implement a user configurable medicine reminder system. The system allows users to set medicine timings and provides alerts using LCD messages and buzzer notifications.
This project implements a real-time medicine reminder system using the LPC2148 microcontroller. The system continuously monitors time using the Real Time Clock (RTC) and compares it with the user-configured medicine schedule.
When the current time matches the stored medicine time, the system generates an alert using a buzzer or LED and displays a reminder message on the LCD display.
Users can configure the system through a 4x4 matrix keypad interface. The system also supports interrupt-based controls using external switches.
The system works based on real-time comparison between RTC time and stored medicine schedules.
- RTC continuously updates time
- User sets medicine timings
- System compares both values
- If match occurs → Alert triggered
- User acknowledges → System resets
