本文介绍了一个基于Arduino Mega和3.2英寸TFT触摸屏的多功能音乐播放器和闹钟项目。主屏幕显示时钟、日期和温度信息，并有音乐播放器和闹钟按钮。音乐播放器界面包含播放、上一首、下一首按钮，音量条和进度条。闹钟界面允许用户设置小时和分钟。当闹钟响起时，会以更高音量播放歌曲。项目使用BY8001 MP3模块和DS3231实时时钟模块。通过定制引脚接头解决TFT屏蔽阻挡问题，并通过串行通信控制MP3模块。
概述
主屏幕上有一个大时钟、日期和温度信息，以及音乐播放器和闹钟两个按钮。

Arduino触摸屏音乐播放器主屏幕
进入音乐播放器后，点击屏幕中间的大“播放”按钮即可开始播放音乐。旁边还有两个按钮，分别用于播放上一首或下一首歌曲。

这些按钮上方是歌曲进度条，屏幕底部有一个音量条和两个用于降低和增加音量的按钮。右上角有一个时钟，左侧是“菜单”按钮，可返回主屏幕。

另一方面，如果我们进入闹钟，我们可以使用两个按钮来设置小时和分钟来设置闹钟。

当闹钟响起时，一首歌曲将以更高的音量开始播放，并一直播放直到我们按下“关闭”按钮。

工作原理
现在让我们来看看这款设备的工作原理。它使用一块 Arduino Mega 开发板和一个 3.2 英寸 TFT 触摸屏，并配有合适的屏蔽罩，用于将屏幕连接到 Arduino 开发板。音乐播放使用 BY8001 MP3 播放器模块，闹钟使用 DS3231 实时时钟模块。

电路原理图
这是该项目的电路原理图：

我们可以在这里注意到，TFT 屏蔽阻挡了 Arduino 板的空闲引脚，因此我们需要制作一个定制的引脚接头，以便能够将它们插入屏蔽和 Arduino 之间。

Arduino 和 TFT 屏幕的定制引脚头
还要注意，为了给 Arduino 供电，我们需要将额外的针头焊接到屏蔽上的 5 V 针脚，因为屏蔽已经使用了所有 Arduino VCC 针脚。

将所有东西连接好后，我们就可以开始对 Arduino 进行编程了。不过，在继续之前，我建议您先看看我之前关于TFT 触摸屏和DS3231 实时时钟模块的详细教程。至于 MP3 播放器模块，我会在本文中简单讲解一下。

BY8001-16P MP3播放器模块
BY8001-16P 是一款 MP3 模块，支持 MicroSD 卡播放，支持 MP3 和 WAV 音频格式。模块内置 3W 功放，可直接驱动单个 3W 扬声器。

BY8100-16P MP3播放器模块
MP3 播放器模块可以使用 5 个输入引脚进行按钮控制，也可以通过串行通信使用微控制器进行控制。

BY8100-16P MP3播放器模块单片机控制
请注意，模块的串口引脚工作电压为 3.3V，因此模块的 RX 引脚需要通过一个 1K 电阻连接到 Arduino 的 TX 引脚。另请注意，A、B 和 C 三个端口用于选择控制模式。如需使用微控制器控制模块，则需要移除这三个引脚上的电阻。引脚 6 和 7 可用于直接连接低功率扬声器，如果使用外部放大器，则可使用引脚 4 和 5。

至于 Arduino 部分，最简单的方法是使用BY8001 库，该库可从 GitHub 下载。打开一些演示示例，就能了解它的工作原理。因此，在设置部分初始化模块后，我们可以使用任何自定义函数来控制模块。

构建设备
我使用 Solidworks 进行了设计，它的外观如下。

Arduino触摸屏音乐播放器和闹钟外壳Solidworks模型
您可以下载此模型，以便在此处进行测量：

对于这个项目，我选择使用铝板，并用多功能工具将其切割成合适的尺寸。然后在桌子边缘，借助一些夹具和板条，我将铝板弯曲。

无需压力机即可折弯金属板
至于扬声器，我打印了一个圆形图案，将其固定到位，然后使用钻头钻出所有孔。

标记侧面
之后，我将侧面切割成适当的形状，并使用胶枪将它们固定到之前弯曲的金属板上。

最后，我给金属板盒子涂了漆，准备安装电子元件了。同样，我用胶枪把所有元件固定好，然后把所有部件连接在一起，最后用两个螺栓固定了设备的后盖。

将电子元件安装到外壳上
就这样，欢迎在下面的评论部分提出任何问题。
