1、創制智能遙控小車程序的設計講解#defineIN14#defineIN25定義In1接arduino的4引腳，In2接5引腳#defineIN36#defineIN47/定義IN3接arduino的6引腳，IN4接7引腳voidforward();voidback();voidturnLeft();voidturnRight();voidturnbackLeft();voidturnbackRight();voidturnLeftOrigin();voidturnRightOrigin();void_stop();/這里是把我們用到的函數都聲明一遍voidsetup()pinMode(IN1,
