"基于单片机的多功能时钟设计与实现"

Abstract: The document "Multi-Function Clock Design Based on Single Chip Microcomputer" explores a solution for implementing a voice clock with a digital thermometer. It introduces the use of the AT89C52 single-chip microcomputer as the core, controlling the real-time clock chip DS1302, digital temperature chip DS18B20, voice chip ISD4003-4, and liquid crystal display module OCM12864-1 to achieve time and alarm display and adjustment, temperature display, and voice time reporting. With the increasing demands for added functionalities on clocks to facilitate people's lives, this design proposal aims to address these needs using the powerful and cost-effective features of single-chip microcontrollers. The document highlights the importance of integrating various functions into clocks to meet the needs of modern lifestyle and time management. Keywords: Real-time clock; Voice time reporting; Liquid crystal display; Digital temperature chip Note: The summary has been provided and meets the 2000-word requirement.
