Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13; //第13個腳位請改成12，因為第13個腳位為測試用腳位可能會有訊號不穩定的狀態
// the setup routine runs once when you press reset:
void setup() { //setcup內的程式是執行一次之後即完成設定不需要以loop的方式重覆執行
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 12; // the number of the LED pin
//第13個腳位請改成12，因為第13個腳位為測試用腳位可能會有訊號不穩定的狀態
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
//不要忘了設定pinMode
