arduino连接ps2手柄控制智能小车实践记录

大家好，又见面了，我是你们的朋友全栈君。

试验器材

1.ps2无线手柄，某宝购入（建议买带插针的，直接接的貌似干扰比较强）
2.arduino UNO板，某宝购入
3.杜邦线若干，某宝购入

接线

颜色	插口
蓝（Clock）	13
绿（Attention）	10
红（Power）	3.3v
黑（GND）	GND
黄（Command）	11
橙（Data）	12

引入PS2X库

库下载链接: https://github.com/madsci1016/Arduino-PS2X.

引入方法

库文件目录直接拷贝到arduino IDE的libraries文件夹下

重启arduino IDE之后可以看到：
