一，具体实现：

1，通过web界面设置闹钟时间；

2，LCD上显示实时时间；

3，保存每天唤醒你所花的时间。

二，工作原理：

该闹钟具有多项实用性，可以通过手机web设置闹钟；闹钟到点后，蜂鸣器响起，LCD背景显示红色；LCD上显示实时时间；按键停止闹钟，保存闹钟响铃时间。

三，硬件搭建

使用Grove* Starter Kit Plus套件，包括

1，Arduino breakout套件；

2，Grove按键；

3，Grove蜂鸣器；

4，Grove RGB LCD显示器；

组装：

1,Grove按键连接到D6上；

2，Grove蜂鸣器连接在D5上；

3，Grove RGB LCD显示器接在任意一个I2C接口上。

三，源码

四，结果

首先在打开手机或者pc机web设置闹铃时间。

Lcd上事实显示当前时间

到闹铃设置时间后，lcd背景红白开始闪烁。蜂鸣器响起。

按键后停止响铃。保持叫醒你的时间。

整个过程的打印信息。
