51单片机开发的8道门出入记录控制板，具有RTC时钟功能，同时具有声光抱紧，能实时的记录被监控门的打开时间。本案例只有8路，但可以方便的扩展至32路。-51 MCU development of 8 door access control panel recorded with RTC clock function, both sound and light to hold fast, can be monitored real-time record of the time the door opened. This case is only 8-way, but can be easily extended to 32.

数码时钟显示，用8位LED软件译码动态显示，P0为字段码,P2为位选码，数码管共阳， key0为位选键；key1为加“1键；key2为减“1”键。-Digital clock display with 8 LED dynamic display software decoding, P0 code for the field, P2 election code for the digital, digital tube were positive, key0 bond election for the position key1 to add " 1 button key2 to reduce the" 1 " button.
