如何在Arduino中製作有限循環

Question

我是編碼領域的初學者，特別是在Arduino中。我一直在做很多項目，但我遇到了一個問題。我似乎無法弄清楚如何製作一個有限循環。我正在尋找類似於while循環，四次後停止。這裏是它將被實施的地方，讓你更好地瞭解我正在尋找的東西。

#include <Servo.h> 

int thumbPin = 2; 
int ndxPin = 3; 
int midPin = 4; 
int rngPin = 5; 
int pnkyPin = 6; 

Servo thumb; 
Servo index; 
Servo middle; 
Servo ring; 
Servo pinky; 
void setup() { 
    Serial.begin(9600); 

    thumb.attach(thumbPin); 
    index.attach(ndxPin); 
    middle.attach(midPin); 
    ring.attach(rngPin); 
    pinky.attach(pnkyPin); 
} 
void loop() { 
    /* I want this code in the comment to be ran four times, then continued on to the code after 
    thumb.write(0); 
    delay(20); 
    thumb.write(0); 
    index.write(0); 
    middle.write(0); 
    ring.write(0); 
    pinky.write(0); 

    thumb.write(150); 
    index.write(150); 
    middle.write(150); 
    ring.write(150); 
    pinky.write(150); 
    */ 
    thumb.write(0); 
    index.write(0); 
    pinky.write(0); 

    middle.write(0); 
    thumb.write(150); 
    pinky.write(150); 
}

你想要一個for循環：https://www.arduino.cc/en/Reference/For

for (int i = 0; i < 4; i++) { 
    thumb.write(0); 
    delay(20); 
    thumb.write(0); 
    index.write(0); 
    middle.write(0); 
    ring.write(0); 
    pinky.write(0); 

    thumb.write(150); 
    index.write(150); 
    middle.write(150); 
    ring.write(150); 
    pinky.write(150); 
}
