爲什麼這個Arduino代碼不起作用？

Question

爲什麼此代碼不起作用？ 我在http://www.codebender.cc上運行這個Arduino代碼，它不會在我的Arduino Uno上運行。當我在串行監視器上運行時沒有打印出來，我完全不知道爲什麼？ 看看...

const int button1 = 8; 
const int button2 = 9; 
const int button3 = 10; 

int ison1 = 0; 
int ison2 = 0; 
int ison3 = 0; 

int x = 1; 
int y = 1; 
int z = 1; 

void setup() 
{ 
    pinMode(button1, INPUT); 
    pinMode(button2, INPUT); 
    pinMode(button3, INPUT); 
} 

void go() 
{ 
    Serial.print("Press button 1 (Furthest to the right)..."); 
    while (x == 1){ 
     ison1 = digitalRead(button1); 
     if (ison1 == HIGH){ 
      Serial.print("Well done!"); 
      x = 2; 
     } 
    } 
    Serial.print("Press button 2 (The middle one)..."); 
    while (y == 1){ 
     ison2 = digitalRead(button2); 
     if (ison2 == HIGH){ 
      Serial.print("Well done!"); 
      y = 2; 
     } 
    } 
    Serial.print("Press button 3 (Furthest to the left)..."); 
    while (z == 1){ 
     ison3 = digitalRead(button3); 
     if (ison3 == HIGH){ 
      Serial.print("Well done!"); 
      z = 2; 
     } 
    } 
    Serial.print("You have completed the test!"); 
} 


void loop() 
{ 
    delay(5000); 
    go(); 
    exit(0); 
}

一下添加到setup：

Serial.begin(9600); 

我做過很多次... :)
