Double LED Blinking : 5 Steps

This Arduino project is a revised version of the project "How to Blink LED Using Arduino" :)

Step 1: Prepare 準備材料

兩個LED燈（自行選色）
兩個電阻
Arduino Leonardo
麵包板
三條電線
USB連接埠
裝飾物蓋住LED燈泡(如果想做成夜燈類)

Step 2: 組裝

（如上圖～！）

Step 3: Download or Copy Code to Arduino App 下載或是複製程式碼到Arduino程式

// the setup function runs once when you press reset or power the board
void setup()
{
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
pinMode(11, OUTPUT); //輸入另一個LED
int analogPin = 0;
}
// the loop function runs over and over again forever
void loop()
{
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
digitalWrite(11, LOW);//讓另一個LED暗
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
digitalWrite(11, HIGH);//讓另一個LED亮
delay(1000); // wait for a second
}
