请写一段使用arduino控制四足蜘蛛机器人的代码

可以参考下面这段代码：int leftFront = 2;
int rightFront = 3;
int leftBack = 4;
int rightBack = 5;void setup(){
pinMode(leftFront, OUTPUT);
pinMode(rightFront, OUTPUT);
pinMode(leftBack, OUTPUT);
pinMode(rightBack, OUTPUT);
}void loop(){
digitalWrite(leftFront, HIGH);
digitalWrite(rightFront, LOW);
digitalWrite(leftBack, HIGH);
digitalWrite(rightBack, LOW);
delay(500);
digitalWrite(leftFront, HIGH);
digitalWrite(rightFront, HIGH);
digitalWrite(leftBack, LOW);
digitalWrite(rightBack, LOW);
delay(500);
digitalWrite(leftFront, LOW);
digitalWrite(rightFront, HIGH);
digitalWrite(leftBack, LOW);
digitalWrite(rightBack, HIGH);
delay(500);
digitalWrite(leftFront, LOW);
digitalWrite(rightFront, LOW);
digitalWrite(leftBack, HIGH);
digitalWrite(rightBack, LOW);
delay(500);
}
