這代碼是arduino 實現秒表的功能，但就是缺少一個暫停的控制功能。

//簡單地，如果這樣實現

boolean bPause=false;
void loop(){
buttonState1 = digitalRead(buttonPin1);
buttonState2 = digitalRead(buttonPin2);

if(buttonState2 == 1){ //buttonState2作暫停功能。按一次暫停、再按繼續
      bPause=~bPause;
}

if(bPause==true){ //如果bPause，則返回
      return;
}

if(buttonState1 == 0){             //復位鍵此處程序開始
      clearLEDs();
      pickDigit(1);
      pickNumber((n/x/600)%10); //(n/x/600)%10
      delayMicroseconds(del);

      clearLEDs();
      pickDigit(2);
      pickNumber((n/x/60)%10); //(n/x/60)%10
      delayMicroseconds(del);

      clearLEDs();
      pickDigit(3);
      dispDec(3);
      pickNumber(n/x/10%6); //n/x/10%6
      delayMicroseconds(del);

      clearLEDs();
      pickDigit(4);
      pickNumber(n/x%10); //n/x%10
      delayMicroseconds(del);
      n++;
}else {
      n=0;
}

}
