材料：

彩色杜邦线  若干

arduino 开发板1个

L298n 电机驱动模块 1个

9V 电池一个

直流电机 4个

ps2 无限遥控手柄

一个载体，我这个是个快递纸盒子裁出来的纸板子/各个模块中间用牙签固定的.......

 

将材料按图连接，自己画的

 

 电机AB 保持同方向正转或倒转

 电机CD 保持同方向正转或倒转

 引脚线连接以单独说明为准，1,2,3,4,5,6....

 电池正极接VIN接L298N的12v输入

 

 

实现代码：

//right now, the library does NOT support hot-pluggable controllers, meaning
//you must always either restart your Arduino after you connect the controller,
//or call config_gamepad(pins) again after connecting the controller.


//说明：线连接好后，ps2手柄，前车往前移动，后-车往后移动....
