Interesting Alarm Clock Design Based on MCU
Abstract: The interesting alarm clock described in this article combines many functions into a MCU system. Such as time display and setting, time report, temperature display, and horse race lamp display, and so on. This system taking AT89C52 controller of ATMEL company as main control chip, composed of DS18B20 temperature acquisition module, DS1302 clock module, LCD1602 LCD display module, time report module based on a sounder, horse race lamp display module, and the keyboard control module, use C language for programming, and use Keil software and Proteus software for this design and simulation. Finally it achieved simulations of temperature display, time display and setting, horse race lamp display, and time report by a sounder, and so on. The system features on a high interest, low cost, low power consumption, high precision, stable and reliable, and so on.
