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 article aims to document the completion of an electronic clock project. The goal of this project is to build a circuit built around the breadboard electronic clock that allows it to accurately clock for 1 minute with two timers. The final result of the project was the success of the electronic clock with three timers as well as a series of additional functions such as buzzer, chronograph speed change, and timer reset. All of these functions are successfully simulated in software and set up successfully. There are 74160,7447 main devices and other integrated circuit modules. The future direction of improvement is to improve the appearance and reasonableness of the electronic clock.
