摘要:娱乐是人们生活的一个重要部分，让娱乐变得更加丰富多彩除了可以通过发明创造新的游戏外还可以通过科技手段来改变娱乐方式。对于当今世界来说，娱乐世界已经和电子世界密不可分了。

　　　论文设计的LED电子骰子其意义在于通过模拟传统普通骰子点数来实现普通骰子的功能。设计通过其LED灯的不同组合方式来代表骰子点数，其操作方式简单、可靠，只需按下开关就能获取一个骰子点数。

　　　论文的结构如同本人的设计过程，整个电路分为四个模块，1延时模块，2多谐波振荡器模块，3计数器模块，4显示模块。论文首先介绍在设计过程中用到的核心芯片NE555 和CD4017，同时分别阐述其内部结构和功能，之后分别阐述和分析两块芯片所在模块（多谐波振荡器模块 计数器模块）的功能和意义。紧接着分析延时模块和显示模块的工作方式。每一个模块都分析完后，论文对相连模块再次进行总体分析。当模块与模块之间的工作关系阐述完毕后也就是整个设计电路图设计完毕的时候。最后，从整体上阐述整个电路图的工作过程。简单来说，论文采取了从分到总的框架模式来阐述设计方案。

　　　论文分为六章，第一章主要阐述设计的背景和构思，第二章分别介绍NE555及CD4017的功能，第三章介绍模块和在本设计中选用模块的概念，第思章介绍两两模块之间的直接关系，最后第五章详细阐述整个电路的工作原理。

ABSTRACT:Entertainment is an important part of people's life, let the entertainment become more rich and colorful in addition to create new games through the invention can also be through scientific and technological means to change the way of entertainment. For today's world, the world of entertainment has been closely linked with the electronic world.

　　LED electronic screen design and its significance lies in through the simulation of traditional ordinary sieve points to achieve common filter function. Different combinations of design through the LED lamp to represent a point, its mode of operation is simple, reliable, simply press the switch can obtain a sieve points.

　　The structure of the thesis as the design process I, the whole circuit is divided into four modules, 1 delay module, 2 astable multivibrator module, 3 counter module, 4 display module . Firstly, used in the design process of the core chip NE555 and CD4017, and describes the structure and function of internal, then describes and analyses two chip module (multiple harmonic oscillator module, counter module) function and significance. Followed by an analysis of time delay module and display module works. Each module is analyzed, based on the overall analysis module is connected again. When the working relationship between modules is also described. After the whole design circuit design at the end of. Finally, the working process of the circuit as a whole. In simple terms, this paper adopted from the assigned to the framework to illustrate the design scheme of the total.

　　The thesis is divided into six chapters, the first chapter mainly elaborates the background and idea of design, the second chapter introduces the NE555 and CD4017 functions, the third chapter introduces the concept of module and the module in this design, the forth chapter introduced the relationship between the modules, the last fifth chapters introduced  the working principle of the whole circuit.

　　　设计意义有三点，一它有一定的实用价值，二未来发展意义，三提高自我。从实用价值方面说它一方面能避免在娱乐过程中的作弊现象，另一方面能消除骰子固有的质量问题。在娱乐过程中有的人能凭借自己高超的技艺来控制传统骰子的最终投掷点数，这样就失去了娱乐效果，反而让娱乐蒙上了雾霾，另外大家都知道大自然的物体始终是实物，如果要想从这种实物上得到一个纯粹的数学符号是存在绝对偏差的。就拿骰子来说，人类永远无法让每个面都与同样概率出现。所以，在这种情况下电子骰子从本质上代替了传统骰子的这种不可靠性，让骰子的意义更佳理想化。未来发展意义方面，它即电子骰子能为一些需要此功能的复杂电路模块提供此子模块。除了对外部的作用外它的设计还对我自己有帮助，通过设计的过程，使我自身所学知识得以巩固。
