二、电动汽车模型设计与制作

1、创制智能遥控小车程序的设计讲解#defineIN14#defineIN25定义In1接arduino的4引脚，In2接5引脚#defineIN36#defineIN47/定义IN3接arduino的6引脚，IN4接7引脚voidforward();voidback();voidturnLeft();voidturnRight();voidturnbackLeft();voidturnbackRight();voidturnLeftOrigin();voidturnRightOrigin();void_stop();/这里是把我们用到的函数都声明一遍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子函数前进子函数函数功能：控制车前进*/voidforward()digitalWrite(IN1,HIGH);digitalWrite(IN2,LOW);/左轮前进digitalWrite(IN3,HIGH);digitalWrite(IN4,LOW);/右轮

4、前进后退子子函数子函数/*函数函数功能：控制车后退*/voidback()digitalWrite(IN1,LOW);digitalWrite(IN2,HIGH);/左轮后退digitalWrite(IN3,LOW);digitalWrite(IN4,HIGH);/右轮后退/*turnLeft子函数左转子函数函数功能：控制车左转*/voidturnLeft()digitalWrite(IN2,LOW);/左轮静止不动digitalWrite(IN3,HIGH);digitalWrite(IN4,LOW);/右轮前进/*turnbackLeft子函数左后转弯子函数函数功能：控制车左后转弯*/vo

5、idturnbackLeft()digitalWrite(IN1,LOW);digitalWrite(IN2,LOW);/左轮静止不动digitalWrite(IN3,LOW);digitalWrite(IN4,HIGH);/右轮后退/*turnRight子函数右后转弯转子函数函数功能：控制车右后转弯*/voidturnRight()digitalWrite(IN1,HIGH);digitalWrite(IN2,LOW);/左轮前进digitalWrite(IN3,LOW);digitalWrite(IN4,LOW);/右轮静止不动/*turnbackRight子函数右转子函数函数功能：控制车

6、右转*voidturnbackRight()digitalWrite(IN1,LOW);digitalWrite(IN2,HIGH);/左轮后退digitalWrite(IN3,LOW);digitalWrite(IN4,LOW);/右轮静止不动/*turnLeftOrigin子函数原地左转子函数函数功能：控制车原地左转*/voidturnLeftOrigin()digitalWrite(IN1,LOW);digitalWrite(IN2,HIGH);/左轮后退digitalWrite(IN3,HIGH);digitalWrite(IN4,LOW);/右轮前进/*turnRightOrigin子函数原地右转子函数函数功能：控制车原地右转*/voidturnRightOrigin()digitalWrite(IN1,HIGH);digitalWrite(IN2,LOW);/左轮前进digitalWrite(IN3,LOW);digitalWrite(IN4,HIGH);/右轮后退/*stop子函数一停止子函数
