With digital display, a display time, adjust the time and real-time alarm function of the electronic clock, and switch to a temperature display. Design using 12MHZ crystal is connected with the microcontroller STC89C51, STC89C51 chip as the core, the use of dynamic scanning display, through the use of the microcontroller, to achieve the 8 LED digital tube display, alarm clock time adjust time, date, alarm setting, switch the display function through 3 buttons.
