Title   Microcontroller-Based Electronic Calendar                     

Abstract Electronic calendar is a contemporary widely used in people's daily life as a multi-function time tool. It Can be calculated in real time and displays the seconds, minutes, hours, date, month, year, temperature and other information, but also with time calibration and other functions. This design is based on the PIC family of microcontrollers electronic calendar design. Hardware circuit using PIC16F877A microcontroller as the core of the system; by the DS1302 clock chip timing; DS18B20 digital temperature sensor for ambient temperature measurement; Finally KS0108 LCD display; button module consists of a pull-up resistor composed of ordinary keys, used for time calibration. Software program written in C language, mainly by the calendar application, the time adjustment process, public lunar calendar conversion process, temperature testing procedures, and other procedures such as display program subroutines. All programming is completed, the MPLAB for debugging, debugging success in Proteus software embedded microcontroller system simulation.
