标注红色的是错误行，我严重怀疑橙色行也错了。
模仿的是抢答器代码如下
int redled=8; //红色LED 输出
int yellowled=7; //黄色LED输出
int greenled=6; //绿色LED输出
int redpin=5; //红色按键引脚
int yellowpin=4; //黄色按键引脚
int greenpin=3; //绿色按键引脚
int restpin=2; //复位按键引脚定义
int red;
int yellow;
int green;
void setup()
{
pinMode(redled,OUTPUT);
pinMode(yellowled,OUTPUT);
pinMode(greenled,OUTPUT);
pinMode(redpin,INPUT);
pinMode(yellowpin,INPUT);
pinMode(greenpin,INPUT);
}
void loop() //按键循环扫描
{
red=digitalRead(redpin);
yellow=digitalRead(yellowpin);
green=digitalRead(greenpin);
if(red==LOW)RED_YES();
if(yellow==LOW)YELLOW_YES();
if(green==LOW)GREEN_YES();
}
void RED_YES()//一直执行红灯亮，直到复位键按下，结束循环
{
while(digitalRead(restpin)==1)
{
digitalWrite(redled,HIGH);
digitalWrite(greenled,LOW);
digitalWrite(yellowled,LOW);
}
clear_led();
}
void YELLOW_YES()//一直执行黄灯亮，直到复位键按下，结束循环
{
while(digitalRead(restpin)==1)
{
digitalWrite(redled,LOW);
digitalWrite(greenled,LOW);
digitalWrite(yellowled,HIGH);
}
clear_led();
}
void GREEN_YES()//一直执行绿灯亮，直到复位键按下，结束循环
{
while(digitalRead(restpin)==1)
{
digitalWrite(redled,LOW);
digitalWrite(greenled,HIGH);
digitalWrite(yellowled,LOW);
}
clear_led();
}
void clear_led()//清除LED
{
digitalWrite(redled,LOW);
digitalWrite(greenled,LOW);
digitalWrite(yellowled,LOW);
}
各位大神师兄们，谁看得懂啊？？？
在线等待回答，急得要命啊！！！
感谢各位父老乡亲们！！！！！！！！！！
