摘要：随着科学技术的飞速发展，电子技术也获得了飞速的发展，在其推动下，现代写论文代电子产品几乎渗透了社会的各个领域，这有力地推动了社会生产力的发展和社会信息化程度的提高，同时也使现代电子产品性能再竞争和更新中一步步提高，电子产品更新换代的节奏也越来越快。
时 间对人们来说总是那么的宝贵，工作的忙碌性和繁杂性容易使人忘记当前的时间、忘记了要做的事情，当事情不是很重要的时候，这种遗忘无伤大雅。但是，一旦重 要事情，一时的耽误可能会导致不可挽回的大祸。但数字电子钟的产生，给人们带了很大的便利，同时电子钟的报表功能也解决了人们的遗忘问题，促进了人们在工 作之余不会漏掉重要事情。
可红外遥控带温度显示的数字钟是采用数字电路实现对时、分、秒.数字显示的计时装置，广泛用于个人家庭、车站、码头办公 室等公共场所,成为人们日常生活中不可少的必需品。因此，研究数字钟及扩大其应用，有着非常现实的意义，我们也能更加熟练掌握数字钟系统的设计制作。对所 学的专业知识有能力更好的应用在实践方面。

Title： Infrared remote control and display to the ambient temperature digital clock
Abstract：With the rapid development of science and technology, electronic technology has gained rapid development in its promotion of modern electronic products into almost all areas of society, which has effectively promoted the development of social productivity and social information and the degree of improvement but also the modern electronic product performance and then update a step competition and increase the http://www.51lunwen.net/pace of replacement of electronic products is also faster.
   Time for the people is always so valuable, the work of a busy and complex nature of easy to forget the present time, forget to do, when things is not very important time, this forgotten harmless. However, once the important things, a momentary delay may lead to irreversible catastrophe. However, digital electronic clock generation, to people with a great deal of convenience, while the reporting functionality of electronic clock to solve the problem of people forgetting to promote the people's leisure time will not miss important things.
Infrared remote control with temperature display can be a digital clock is used to realize digital circuits hours, minutes and seconds. Figures show that the timing devices, widely used in individual households, stations, terminals offices and other public places, become an indispensable necessity in daily life . Therefore, the study digital clock and expand its application has a very real sense, we can be more familiar with digital clock system designed. Professional knowledge of the learned ability will be better applications in practice.
Keywords: SCM，Infrared Remote Control , Common cathode LED Digital Display, Temperature Sensor
