This project focuses on an IoT-based Tablet Reminder System featuring an ESP32 microcontroller, OLED display, RTC module, buzzer, keypad, and servo motor. It allows users to set, store, and display reminders with accurate timekeeping ensured by the RTC module. Notifications are delivered through a buzzer for auditory alerts and a servo motor for visual cues, enhancing user engagement. Reminders are input via the keypad by entering the date, time, and message. The servo motor, controlled by PWM signals from the ESP32, provides precise movements to physically indicate reminders. The system is designed for local operation but can be extended to IoT platforms like Blynk or Firebase, enabling remote reminder

management and cloud storage. Cloud integration would allow users to modify reminders remotely, receive push notifications on smartphones, and ensure data backup, enhancing convenience and reliability. This solution combines hardware components to create a practical, costeffective system for managing tasks like medication schedules or daily routines. It offers flexibility, scalability, and userfriendly features, making it suitable for diverse needs. With IoT capabilities, the system evolves from a local reminder tool to a connected smart reminder platform, supporting modern lifestyles with both auditory and visual alerts.
