So, I just wanted an Ambient Light for my TV.
\nCould be quite easy.
\nI got an Arduino and a Cheap RGB LED Strip, here is the working diagram:<\/p>\n

\"Ambientlight_Schaltplan\"<\/a><\/p>\n

Arduino gets Info from USB, and switches the right RGB Vvalues accordingly.<\/p>\n

Now my laptop has just to execute this script:
\n
\nimport java.awt.Robot;
\nimport java.awt.AWTException;
\nimport java.awt.event.InputEvent;
\nimport java.awt.image.BufferedImage;
\nimport java.awt.Rectangle;
\nimport java.awt.Dimension;
\nimport processing.serial.*;
\nSerial port;
\nRobot robby;
\nvoid setup()
\n{
\nport = new Serial(this, Serial.list()[0],9600);
\nsize(100, 100);
\ntry
\n{
\nrobby = new Robot();
\n}
\ncatch (AWTException e)
\n{
\nprintln(\"Robot class not supported by your system!\");
\nexit();}}<\/p>\n

void draw()
\n{int pixel;
\nfloat r=0;
\nfloat g=0;
\nfloat b=0;
\nBufferedImage screenshot = robby.createScreenCapture(new Rectangle(new Dimension(1920,1080)));
\nint i;
\nint j;<\/p>\n

for(i=0;i<1920; i=i+2){
\nfor(j=0; j<136;j=j+2){
\npixel = screenshot.getRGB(i,j);
\nr = r+(int)(255&(pixel>>16));
\ng = g+(int)(255&(pixel>>8));
\nb = b+(int)(255&(pixel)); }}<\/p>\n

r=r\/(960*68);
\ng=g\/(960*68);
\nb=b\/(960*68);
\nport.write(0xff);
\nport.write((byte)(r));
\nport.write((byte)(g));
\nport.write((byte)(b));
\ndelay(10);
\nbackground(r,g,b);}
\n<\/code><\/p>\n

It works so perfect!
\nThe light is bright, the colors change nice and fast.<\/p>\n

Only problem..my laptop is way to slow!
\nThis transforms every movie into a dia show..
\nAnd I even just get the RGB info of the upper 12% of the screen.<\/p>\n

Need to
\n– find new software
\n– get new laptop
\n– find new project for my RGB strip;)<\/p>\n","protected":false},"excerpt":{"rendered":"
