ArduBlock程式：
Arduino 原始程式(源自Sketch草稿)：
/* (/*：用在很多行的附註說明，以/*開始，以*/結束。)
Blink(閃爍)
Turns on an LED on for one second, then off for one second, repeatedly.
(不間斷的將Led打開1秒，之後關閉1秒)
*/
// (//此符號是用在附註說明只有1行)
//Pin 13 has an LED connected on most Arduino boards.
//(定義Arduino上的第13個針腳的名稱為 led)
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
//void setup只有在程式執行時執行一次，通常用在定義變數
void setup() {
// initialize the digital pin as an output.
//將led這個變數，初始化定義為輸出的裝置
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
//loop這個程式會不斷的執行
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)開燈
delay(1000); // wait for a second 等待1秒
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW 關燈
delay(1000); // wait for a second 等待1秒
}
