Arduino ， 如何让arduino在同时满足两个条件的时候做一件事情

我想让arduino在两个按键在同时（1/3秒内）按下时让蜂鸣器响。怎么做？

int analogPin5 = 12;
int analogPin1 = 4
;

int val1 = 0;
int val2 = 0;
void setup()
{
Serial.begin(9600);
// 把连接按钮的引脚作为输入:
pinMode(analogPin5, INPUT);
pinMode(analogPin1, INPUT); // setup serial
}
void loop()
{
analogWrite(1,255);
val1 = digitalRead(analogPin5);
val2 = digitalRead(analogPin1);
Serial.println(val1);
Serial.println();
Serial.println();
Serial.println();
Serial.println(val2);
analogWrite(3,0);
analogWrite(5,0);

tone(9,LOW);

／／在1/3秒内同时＝＝1后执行的代码

／／下面是分开来的代码
if(val1==1)
{analogWrite(3,255);tone(9,500);delay(1000); }
else if(val1>0)
{analogWrite(3,0);analogWrite(5,0);}

if(val2==1)
{analogWrite(5,255);tone(9,500);delay(1000);}
else if(val2>0)
{analogWrite(3,0);analogWrite(5,0);}

}

Answer 1

if ( (val1==1) && (val2==1) )
{analogWrite(3,255);tone(9,500);delay(1000); }
else if(val1>0)
{analogWrite(3,0);analogWrite(5,0);

analogWrite(5,255);tone(9,500);delay(1000);}
else if(val2>0)
{analogWrite(3,0);analogWrite(5,0);}

但是我需要有1/3秒的容忍度，就是如果两个按钮分别在1/3秒内按下执行一个条件

加个时间记录就好了 判断按键时间间隔
