[项目] 【Arduino 动手做】DIY Arduino 模拟时钟

[复制链接]
一个有趣的漂亮的模拟式时钟，它的构建也非常简单。

这次我将向您展示如何制作一个有趣的好看的时钟，它的构建也非常简单。确切的时间时间以椭圆形模拟时钟的形式显示在大型 LCD 屏幕上。时间也可以借助三个按钮轻松调节。

在这种情况下，为了简单起见，没有使用实时时钟模块，因此精度没有那么高，主要取决于微控制器内的晶体。
该设备由几个组件组成：
- Arduino Nano 微控制器
- 基于 ST7920 芯片的 LCD 显示屏，分辨率为 128x64 点
- 和三个按钮

基本代码是从 blaber.com.pl 站点下载的，方法是将其调整为上述显示，比原始显示更易于访问且便宜得多。代码是对数字时钟的修改，虽然它可以工作，但它仍然需要在图形上做大量的工作。这是如何使用 u8g2 库在不同类型的显示器上绘制对象和写入文本的一个很好的示例。

开机时，时间是12：00，我们必须手动设置当前时间。我们在三个按钮的帮助下使它变得简单。中间按钮用于进入设置模式，第一次点击设置分钟，第二次点击小时。在设置模式下，箭头在其他两个按钮的帮助下移动。在精度方面，考虑到我们不使用 RTC 模块，时钟非常准确。就我而言，24 小时实时与时钟之间的差异只有几秒钟。
最后，将设备内置到一个合适的盒子中，由厚度为 3 毫米和 5 毫米的 PVC 材料制成，并涂有不干胶彩色壁纸。
