ATDUINO程式問題

想請問如何使用紅外線感測計數輪子轉動的圈數程式如下

1. const int PIRSensor = 2;
   
2. int val = 0;
   
3. void setup()
   
4. {
   
5.   Serial.begin(9600);
   
6.   pinMode(PIRSensor,INPUT);
   
7.   pinMode(13,OUTPUT);
   
8. }
   
9. void loop(){
   
10. 
    
11. 
    
12.   int i;
    
13.   i = digitalRead(PIRSensor);
    
14.   if(i == LOW){
    
15.   digitalWrite(13,HIGH);
    
16.   val += val + 1;
    
17. 
    
18.   }
    
19. 
    
20.   
    
21.    Serial.print(val);
    
22.    delay(1000);
    
23. }

這是我計數的程式可是我要如何加到我的自動車程式中，我想再直線前進的時候用紅外感測來控制輪子轉的圈數達到我要的，已圈數控制直線距離。下面是車子的程式

1. #include <HMC5883L.h>
   
2. #include <Wire.h>
   
3. 
   
4. HMC5883L compass;
   
5. 
   
6. void Angle()
   
7. {
   
8.   MagnetometerRaw raw = compass.ReadRawAxis();
   
9.   MagnetometerScaled scaled = compass.ReadScaledAxis();
   
10.   float yHeading = atan2(scaled.ZAxis, scaled.XAxis);
    
11. 
    
12.   if(yHeading < 0) yHeading += 2*PI;
    
13.   if(yHeading > 2*PI) yHeading -= 2*PI;
    
14. 
    
15.   int yDegrees = yHeading * 180/M_PI;
    
16. 
    
17.   Serial.print(yDegrees);
    
18.   Serial.print(",");
    
19.   delay(500);
    
20. }

建議你試把這行
delayMicroseconds(8000000);
改成:
for (int x=0; x <= ???; x++){
        int j;
  j = digitalRead(PIRSensor);
  if(j == LOW){
  digitalWrite(13,HIGH);
  val += val + 1;
   } }
??? >也許2000至4000之間
