用可變電阻控制RGB三色

int valLight = 0;
int valDark = 0;

void setup() {               

  pinMode(9, OUTPUT);    
  pinMode(10, OUTPUT);    
  pinMode(11, OUTPUT);   
  Serial.begin(9600); // open serial
}

void loop()
{
  valLight = analogRead(0);
  valDark = analogRead(1);
  Serial.print("Light ");
  Serial.println(valLight, DEC);
  Serial.print("Darkt ");

  Serial.println(valDark, DEC);
  for(int i=9;i<12;i++){
    digitalWrite(i, HIGH);  
    delay(valLight/4);             
    digitalWrite(i, LOW);   
    delay(valDark/4);            
  }

}

RGB三色燈光PWM控制

void setup() {               
  pinMode(9, OUTPUT);    
  pinMode(10, OUTPUT);    
  pinMode(11, OUTPUT);    
}

void loop()
{
  analogWrite(9, 128);   //R
  analogWrite(10, 64);   //B
  analogWrite(11, 100);   //G

}

RGB三色混色閃爍

將RGB的LED塞入乒乓球
利用視覺暫留，製造出混成白色的結果
也可以搖晃造成分色。也可以製造出黃色

void setup() {               
  pinMode(9, OUTPUT);    
  pinMode(10, OUTPUT);    
  pinMode(11, OUTPUT);    
}

void loop()
{
  for(int i=9;i<12;i++){
    digitalWrite(i, HIGH);  
    delay(2);             
    digitalWrite(i, LOW);   
    delay(10);            
  }

}
