37款传感器与执行器的提法，在网络上广泛流传，其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块，依照实践出真知（一定要动手做）的理念，以学习和交流为目的，这里准备逐一动手尝试系列实验，不管成功（程序走通）与否，都会记录下来—小小的进步或是搞不掂的问题，希望能够抛砖引玉。

【Arduino】168种传感器模块系列实验（资料代码+仿真编程+图形编程）
实验九十五：APDS-9960 GY-9960-3.3 RGB红外手势传感器 方向识别模块
1、工具-管理库-搜索“SparkFun_APDS-9960”库-安装
2、项目：串口显示测量的四组数据（未接入LCD）
3、实验接脚
SDA = A4
SCL = A5
GND = GND
VCC = 3.3V
