在Blogger 貼上程式碼一

如何在Blogger 網頁內，貼上如下圖美美的程式碼呢?一點也不困難，讓我們繼續看下去。

程式貼碼測試01

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

程式碼輸出測試三

這是用來測試程式碼輸出的效果。

Source file

 1 // 按鍵鋼琴，利用按鈕播放音階
 2 const int speaker=2;
 3 const int sw[8]={4,5,6,7,8,9,10,11} ;

10   for(int i=0;i<8;i++) 
11      pinMode(sw[i],INPUT) ;

13 }
14 
15 void loop() {
