Abstract: Designing a time-operated electrical appliances control system utilizing five relays, aimed at automating the switching of household or industrial devices to enhance energy efficiency and user convenience. The system employs a microcontroller (Arduino UNO) integrated with a Real-Time Clock (RTC) DS3231 module to maintain accurate timekeeping. Users can program specific ON and OFF times for each appliance through a user-friendly interface, allowing for precise control over device operation. The five relays serve as actuators, each connected to a separate appliance, enabling independent control based on the predefined schedules. An 16x2 LCD Display Module provides real-time feedback, displaying current time and the status of each appliance. The system's modular design ensures scalability, allowing for the addition of more relays to accommodate additional devices as needed. By automating the control of electrical appliances, the system reduces unnecessary energy consumption, thereby contributing to cost savings and environmental conservation. Its applications are versatile, ranging from residential settings to commercial and industrial environments where scheduled operation of devices is beneficial. The successful implementation of this system demonstrates the feasibility and advantages of integrating microcontroller-based automation in managing electrical appliances, paving the way for more sophisticated energy management solutions in the future. Keywords – Arduino UNO, RTC DS3231 Module, 16x2 LCD Display Module
