[2020]'春节宅家一起造“之‘工程师的情人节这样过‘

才刚过完年没几天，西洋情人节马上就来报到了。对很多人来说，这表示得花点钱买情人节卡片、巧克力或鲜花等传统的礼物，或者是和情人一起吃顿晚餐。虽然都是精心挑选的礼物或营造的气氛，但发自内心且亲手打造的创意设计更让人开心，毕竟它是专为某个人特别制作的，可不是商店货架上就能看到的商品啊！

怎样成功赢得情人脸上那个感动又满意的笑容？

先发个样板视频，有时间再发个成品视频

这次的项目通过一个颜色传感器做的‘盒子’给爱人做演示，让它来识别周围的物体，当识别到你的爱人衣服的颜色（你得事先知道你的爱人的衣服颜色，程序是预先烧录的），接受到信号的别在你衣服上的LED灯会开始做呼吸灯闪烁。这样你就可以跟你的爱人说‘’你看，神奇吧，他们有感应‘’

工作原理：用色彩模块识别到红色后（也可以设置其他颜色）,程序里可选颜色是红，绿，蓝，橙，黄（颜色相似则归于相似色），信号通过433M模块的发射端发送到接收端。接受端得到信号后，会指令LED开始闪烁。

硬件如下：

Arduino pro mini x 2

433发射端

433接受端

颜色模块DF-34725

接下来是连线图。
