 Multifunction Microcontroller-based Digital Clock

Abstract    In recent years, with the continuous development of computers, SCM applications are constantly deepening, microcontroller as the core control system, more and more used in various fields of life and military. Microcontroller as the core of the system will be based on the general characteristics of the hardware and software of the specific structure and specific application objects combine to make it more perfect. Microcontroller-based multi-functional digital clock described in this article is a microcontroller as the core of a specific application, a combination of hardware and software. The design consists of five specific modules. LCD module: time, temperature and other information in digital form visual show. Temperature acquisition module: using temperature sensors and temperature displayed on the LCD screen. Key modules: the adjustments and settings functions. Time processing module: the timing of the time and having a leap year compensation. Infrared Module; with the remote control via infrared remote control. This design compared to conventional clock, functional persification, higher accuracy, low cost and so on a series of advantages, market prospects are very broad.
