Description: 基于DS1302的数码管时钟电路设计LED数码管时钟电路采用24h计时方式，时、分、秒用六位数码管显示，其中小时、分、秒之间用小数点分开。该电路采用AT89C52单片机和DS1302实时时钟芯片，使用5V电源进行供电，使用两个按键进行调时，调整过程中被调节的分钟或时钟将进入闪亮状态，看上去非常直观，另外，本设计还具有快速调时功能，当按键一直被按下时，便进入快速调时状态。[第一段]
-DS1302 based digital control clock circuit design LED digital tube clock circuit 24h time mode, hour, minute, second with six digital tube display, including hours, minutes and seconds between the use of the decimal point separately. The circuit used AT89C52 MCU and DS1302 real time clock chip, the use of 5V power for electricity, the use of two buttons to tune, the adjustment process by regulating the minutes or the clock will be flashing, and looks very intuitive, In addition, The design also features fast transfer time, when the button has been pressed, they enter a state of rapid adjusting the time.
