The resource is based on 8051 and 1602 LCD clock display, time can display hours, minutes, seconds, year, month, and day. Function regularly playing a song, tune, based on the temperature sensor setting the temperature alarm and other functions, the resource also given proteus circuit simulation. The simulation results and experimental results exactly true, is essential to learn microcontroller development resources. Note: change the code is the first complete study of the experimental program after completion YAN Ting OF MCU development tutorial.
