淘宝买的，四键遥控器。

我换10,11,12,13口作为遥控器信号输入端了，还是这样！

但不对啊，若是遥控器，怎么可能全是1为判断条件呢？你能发一下你的硬件图么 ...

void setup()
{
  pinMode(2,OUTPUT);
  pinMode(3,OUTPUT);
  pinMode(4,OUTPUT);
  pinMode(5,OUTPUT);
  pinMode(7,OUTPUT);
  pinMode(8,OUTPUT);
  pinMode(10,INPUT);
  pinMode(11,INPUT);
  pinMode(12,INPUT);
  pinMode(13,INPUT);
  
}
void loop()
{
  int FORW=digitalRead(10);
  int BACK=digitalRead(11);
  int LEFT=digitalRead(12);
  int RIGHT=digitalRead(13);
  if(FORW==1)
  {digitalWrite(2,0);
   digitalWrite(4,1);
   analogWrite(3,250);
   digitalWrite(7,0);
   digitalWrite(8,1);
   analogWrite(5,250);
  }
  else if(BACK==1)
  {digitalWrite(2,1);
   digitalWrite(4,0);
   analogWrite(3,250);
   digitalWrite(7,1);
   digitalWrite(8,0);
   analogWrite(5,250);
  }
  else if(LEFT==1)
  {digitalWrite(2,0);
   digitalWrite(4,1);
   analogWrite(3,250);
   digitalWrite(7,1);
   digitalWrite(8,0);
   analogWrite(5,250);
  }
  else if(RIGHT==1)
  {digitalWrite(2,1);
   digitalWrite(4,0);
   analogWrite(3,250);
   digitalWrite(7,0);
   digitalWrite(8,1);
   analogWrite(5,250);
  }
  else
  {digitalWrite(2,0);
   digitalWrite(4,0);
   analogWrite(3,0);
   digitalWrite(7,0);
   digitalWrite(8,0);
   analogWrite(5,0);
}

又奋斗一天，终于搞定，原来if语句和if else还是有区别的！
下面继续努力，想在车上加3或4自由度的机械手，再加摄像头之类的扩展，继续学习！
谢谢回复的朋友和论坛，对我的帮助！
