[Arduino] Photoresistor and Mood Lamp

No commentsArduino, C, Devmaggio 17th, 2011

Easy way,
an RGB led with random colors that light on when light is off connected to Arduino Uno!



Another bullshit!

Color code here:

10
11

  }
 
  for (int x=0; x<256; x++) {
    red = int(RGB1[0]);
    green = int(RGB1[1]);
    blue = int(RGB1[2]);
   
    analogWrite (RedPin, red);
    analogWrite (GreenPin, green);
    analogWrite (BluePin, blue);
    delay(10);
   
    RGB1[0] -= INC[0];
    RGB1[1] -= INC[1];
    RGB1[2] -= INC[2];
  }
 
  for (int x=0; x<3; x++) {
    RGB2[x] = random(556)-300;
    RGB2[x] = constrain(RGB2[x], 0, 255);
    delay(10);
  }

[Objective C] UIColor from RGB

No commentsDev, Objective-Cagosto 2nd, 2010

Do you want to create an UIColor from RGB value?

Here the snipplet:

1
2
3
4
#define UIColorFromRGB(rgbValue) [UIColor \
colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \
green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \
blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

to use:

1
UIColor aColor = UIColorFromRGB(0xFF00FF);

it’s all!
