【掌控】光线传感器—送给妈妈的礼物

[复制链接]

母亲是一艘大船,载着我驶向大海,去追寻生命的奥秘,去探索世界的神奇;

母亲是一座高山,蕴藏着万物,哺育我成长,强壮我的身心;

母亲是丝丝春雨,滋润着大地万物;

母亲,我爱你，你是我心中永远的最爱;

母亲马上过生日了,为妈妈设计一个小礼物—智能灯光生日音乐盒, 祝母亲永远幸福,永远健康!

一、要求：

1、当light>3000时，全部蜡烛点亮，红灯亮，音乐BIRTHEDAY 响起

2、当light>1500时，一半蜡烛点亮，蓝灯亮，音乐BIRTHEDAY响起

3、当light>200时，三分之一蜡烛点灭，绿灯亮，音乐BIRTHEDAY响起

4、当light<200时，蜡烛未亮，灯灭，音乐BIRTHEDAY停止

二、生日蛋糕图形处理：

1、利用美图秀秀分别将生日蛋糕分辨率图片处理成45*45（蛋糕）

2、利用取模工具对图片进行取模。网上有PCtoLCD、lcd image converter等取模软件，可根据自己喜好自行选择。以下使用的是Img2Lcd工具。

步骤1.导入刚才修改后的图片

步骤2.选择参数,输出数据类型[C语言数组]、扫描模式[水平扫描]、输出灰度[单色]、宽高[128*64]（注意：一定要根据实际图片效果来调整亮度和对比度，已达到最佳显示效果）

步骤3.保存数据：点击保存，填写好文件名，自动会弹出图像的取模值。但是我们在使用的时候一定要注意：前面的注释部分（下图中的蓝色部分）不能写入一会儿的程序中。

三、编写代码

1.库的说明：

掌控库：mpython*; 音乐库：music.py;时间库：time.py; 图片库：framebuf.py

2.编程流程图：

3.代码编写
