本帖最后由 弘毅 于 2012-12-18 23:44 编辑最近利用手头的LCD12864中文屏幕，DS1302时钟模块，DHT11温湿度传感器，自制的Arduino最小系统，芯片为Atmega8 ，开发一个电子闹钟。先上图：
这是正面外观、屏幕显示主界面（左上角的圆圈代表闹铃开启，最下面显示当前温度和湿度）
不做操作10秒后，会自动进入睡眠模式，屏幕背光灯亮度减弱，屏幕随机位置显示时间和温湿度轮换，按任意键唤醒回到主界面。
侧视图：
后视图：
自己做的最小系统，芯片是 Atmega8，之前露过面的哦。
可惜只写了主界面和简化的睡眠模式，Atmega8芯片容量不够了，无法继续写更多功能，只好先来个简化的。
上个视频看看：

随后，换开发用的 Arduino UNO板子，继续写功能模块
好了，终于都写完了，实现了日期、时间、温度、湿度显示，睡眠模式，日期时间设置，闹铃开启关闭，闹铃时间设置功能。

缺陷：设计睡眠功能，主要是为了防止长期单点显示对屏幕造成伤害，另外减弱背光也是想省电，但省电结果不是很理想，还是比较费电的。 // A1/15 确定按钮; A2/16 下移按钮; A3/17 上移按钮; A4/18 返回按钮;
这句代码中，是如何定义A1-A4的按键端口号的？我仿制了一个，能够正确显示图片，但是貌似干扰，图标、设置内容等乱跑。 图片失效啦 {:soso_e154:}求图，我也做个学习下！ 幻生幻灭 发表于 2012-12-9 09:07 static/image/common/back.gif

图片怎么老是出错不显示呢？
图片你是上传到图片空间，然后引用链接重新调整大小的吧，因为我看了一下后台服务器记录。。。显示是主动删除了。。。是不是因为图片你img代码引用后，显示了2次。。所以你删除了上传的那一部分。上传的删除的。。引用的也自然没了。
直接使用图片上传。。然后插入图片就好。目前上传的图片，因为论坛编辑器限制，没法调整大小=.=
{:soso_e113:} 我从你空间。。把图片重新转过来了，嘿嘿 弘毅 发表于 2012-12-18 23:33 static/image/common/back.gif

谢谢站长！ 霸气的闹钟，用oled 屏幕会比较省电 好东西！做记号备用！ 改用TFT做显示耗电更少而且更漂亮 感谢楼主 学习中
