资料介绍

这篇文章旨在记录一个电子钟项目的完成过程。这个项目的目标是建造一个搭建在面包板上的电子钟的电路使其能用两个计时器来准确计时1分钟。项目的最终成果是这个电子钟成功包含了3个计时器以及一系列附加功能,比如蜂鸣器、计时速度改变功能,以及计时重置功能。这些功能都用软件模拟成功并且搭建成功了。主要器件有74160,7447等集成电路模块。未来的提高方向是改良电子钟的外观和合理实用性。

This report intends to record the conduction process of the stopwatch project. The project requirement was to build a digital clock circuit that can counter 1 minute on a breadboard using at least two achievement of this project of the group was that a digital clock that included three counters with additional functions such as buzzer, speeding shifting, and preset functions was constructed and simulated successfully. the apparatus used were primarily IC chips such as 74160, 7447 and a big breadboard to build complex and big circuit that was designed. An expected future improvement of conducting this kind of project was that the circuit out-looking was expected to be more clear and beautiful if possible. To achieve this, skillful wiring a...
