代码

// Basic Arduino Microcontroller empty code template
// The setup function runs once when you press Reset or power the board
//定义LED引脚
int led_pin = 5;

void setup() {
//设定引脚为输出模式
    pinMode(led_pin,OUTPUT);
    //点亮LED
}

// The loop function runs over and over again forever

void loop() {
    digitalWrite(led_pin,HIGH);
    delay(1000);
    digitalWrite(led_pin,LOW);
    delay(1000);
}
