买了一个切诺基的小车，用小米UNO来通讯，但程序上传后小车没动，是什么情况？切诺基与UNO无法正常通信图1

帮忙看下[mw_shl_code=cpp,true]int speedPin_M1 = 5;    //M1 Speed Control
int speedPin_M2 = 6;    //M2 Speed Control
int directionPin_M1 = 4;    //M1 Direction Control
int directionPin_M2 = 7;    //M1 Direction Control

void setup(){
}

void loop(){
carAdvance(100,100);
delay(1000);
carBack(100,100);
delay(1000);
carTurnLeft(250,250);
delay(1000);
carTurnRight(250,250);
delay(1000);
}

void carStop(){                //  Motor Stop
  digitalWrite(speedPin_M2,0);
  digitalWrite(directionPin_M2,LOW);
  digitalWrite(speedPin_M1,0);
  digitalWrite(directionPin_M1,LOW);
}

void carAdvance(int leftSpeed,int rightSpeed){       //Move FORkward
  analogWrite (speedPin_M2,leftSpeed);             //PWM Speed Control
  digitalWrite(directionPin_M2,LOW);
  analogWrite (speedPin_M1,rightSpeed);
  digitalWrite(directionPin_M1,HIGH);
}

void carBack(int leftSpeed,int rightSpeed){    //Move BACKrward
  analogWrite (speedPin_M2,leftSpeed);
  digitalWrite(directionPin_M2,HIGH);
  analogWrite (speedPin_M1,rightSpeed);
  digitalWrite(directionPin_M1,LOW);
}

void carTurnLeft(int leftSpeed,int rightSpeed){    //Turn Left
  analogWrite (speedPin_M2,leftSpeed);
  digitalWrite(directionPin_M2,HIGH);
  analogWrite (speedPin_M1,rightSpeed);
  digitalWrite(directionPin_M1,HIGH);
}
void carTurnRight(int leftSpeed,int rightSpeed){    //Turn Right
  analogWrite (speedPin_M2,leftSpeed);
  digitalWrite(directionPin_M2,LOW);
  analogWrite (speedPin_M1,rightSpeed);
  digitalWrite(directionPin_M1,LOW);

只闪灯，小车不走，连轮子都不动
