［互动装置分享］情人节要到了，请爱护一下“我” DF创客社区

情人节马上就到了，朋友圈即将被秀恩爱攻占，然而情人节的我依然是一只狗做了一个互动装置来表达心里苦
（以及快写完的时候没保存真是气死了）
［互动装置分享］情人节要到了，请爱护一下“我”图3

视频：

材料：
数字触摸传感器  df商城
ADXL345三轴加速度传感器  df商城 SEN0032
Flex单向弯曲传感器  df商城 SEN0086
Arduino Uno  df商场
IO扩展板  df商城
复模硅胶  淘宝
木板，亚克力板  淘宝
doge贴纸  淘宝
绝缘胶带，铝箔纸  五金店
软件：arduino，processing

“我”制作过程：
做这部分的时候忘记记录了，因为传感器老是出问题［哭］……简单的来说就是用激光切割在很多块亚克力板上切了“我”，然后把它们叠在一起，在下面垫一块完整的亚克力板，这样就出现了一个凹槽，先倒一半的硅胶，等它干了贴绝缘胶带，放传感器，在触摸传感器上贴铝箔纸，再贴绝缘胶带，倒另一半硅胶。
注意在边缘留一点空白，硅胶无法和绝缘胶带黏合。

Arduino代码：
