RGB1

程式碼
analogWrite(pin,v)  //電壓0~5V，0~255表示
控制燈的強弱調出自己的顏色。可以利用在三原色的實驗。
底下是自己亂寫的(反正不要短路就好了，勇敢的亂寫)

int redPin = 9;  // R petal on RGB LED module connected to digital pin 9
int greenPin = 10;  // G petal on RGB LED module connected to digital pin 10
int bluePin = 11;  // B petal on RGB LED module connected to digital pin 11

void setup()  
{
  pinMode(ledPin, OUTPUT); // sets the ledPin to be an output
  pinMode(redPin, OUTPUT); // sets the redPin to be an output
  pinMode(greenPin, OUTPUT); // sets the greenPin to be an output
  pinMode(bluePin, OUTPUT); // sets the bluePin to be an output
}
