### BlocklyDuino 程式 (RGB\_Blink)
共陽極的LED模組，腳位需為低電位才會亮燈；高電位才會關燈。而本專案使用「函式」的模組，來定義亮紅燈、藍燈、綠燈和關燈。
程式在初始化時是全部關燈，在重複執行時亮起紅燈、藍燈、綠燈和關燈，並都是間隔一秒。
### Arduino 程式(RGB\_Blink.ino)如下
```arduino
void Green() {
digitalWrite(8, LOW);
digitalWrite(9, HIGH);
digitalWrite(10, HIGH);
}
void Red() {
digitalWrite(8, HIGH);
digitalWrite(9, HIGH);
digitalWrite(10, LOW);
}
void Blue() {
digitalWrite(8, HIGH);
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
}
void Closed() {
digitalWrite(8, HIGH);
digitalWrite(9, HIGH);
digitalWrite(10, HIGH);
}
void setup()
{
Closed();
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
}
void loop()
{
Red();
delay(1000);
Blue();
delay(1000);
Green();
delay(1000);
Closed();
delay(1000);
}
```
### 程式執行結果:
亮起紅燈、藍燈、綠燈和關燈，並都間隔一秒。
