二、電動汽車模型設(shè)計(jì)與制作

1、創(chuàng)制智能遙控小車程序的設(shè)計(jì)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(shù)都聲明一遍voidsetup()pinMode(IN1,

2、OUTPUT);pinMode(IN2,OUTPUT);pinMode(IN3,OUTPUT);pinMode(IN4,OUTPUT);Serial.begin(9600);inti;voidloop()if(Serial.available()i=Serial.read();switch(i)case'1':turnLeft();break;case'2':forward();break;case'3':turnRight();break;case'4':turnLeftOrigin();break;case'5'

3、;:_stop();break;case'6':turnRightOrigin();break;case'7':turnbackLeft();break;case'8':back();break;case'9':turnbackRight();break;/*forward子函數(shù)前進(jìn)子函數(shù)函數(shù)功能：控制車前進(jìn)*/voidforward()digitalWrite(IN1,HIGH);digitalWrite(IN2,LOW);/左輪前進(jìn)digitalWrite(IN3,HIGH);digitalWrite(IN4,LOW);/右輪
