实现一个简单的电子钟的功能，可是显示时、份、秒，还能置位，恢复默认设置！是初学者的好帮手！-The realization of a simple function of the electronic bell, but displayed, were seconds, but also home, and to restore the default settings! Is a good helper for beginners!

遥控数字钟应用程序，应用于多种数字钟接口，可以遥控设备，省力。自制LED电子钟在很多电子报刊杂志上都可以见到，但大多数在断电后都要重新设置时间等 参数，给使用带来很多不便。也有用后备电池作为备用电源的，但往往体积较大。本文介绍 的LED电子钟克服了以往的弊端，而且采用了家电通用的红外遥控器进行控制，方便使用。 有一路闹铃输出，可以通过遥控器设置闹铃时间及允许与否。-digital clock remote control applications, digital clock used in a variety of interface, remote-control equipment, effort. Homemade LED electronic bell in many electronic newspapers and magazines can all, but most of the power outages after the re setup time and other parameters to use in many ways. Also useful as a standby battery backup power, but often larger. This paper introduces the LED electronic clock to overcome the shortcomings of the past, and the use of common household appliances infrared remote control, and ease of use. A way Alarms output, the remote control can set the alarm time and allow it or not.

数字钟是一种用数字电路技术实现时、分、秒计时的装置，与机械式时钟相比具有更高的准确性和直观性，且无机械装置，具有更更长的使用寿命，因此得到了广泛的使用。数字钟从原理上讲是一种典型的数字电路，其中包括了组合逻辑电路和时序电路。目前，数字钟的功能越来越强，并且有多种专门的大规模集成电路可供选择-Digital Clock is a digital circuit technology with the hours, minutes, seconds, timing devices, as compared with the mechanical clock has a higher accuracy and intuitive, and no mechanical devices, with more longer life, so be a wide range of use. Digital clock from the principle of speaking, is a typical digital circuits, including combinational logic circuits and sequential circuits. At present, the digital clock and more powerful, and there are a variety of specialized large scale integrated circuits to choose from
