I am currently trying to use arduino and processing to create an ambilight effect for my computer monitor. I have the following code in my arduino but whenever i try to run it i get a fairly large list of errors underneath. I appreciate these may be obvious mistakes but I am only just starting out on arduino and could really use some help.
Code as follows:
import java.awt.;
import java.awt.image.;
// Put the right screen size in here
int screenW = 1366;
int screenH = 768;
// Preview window size
int windowW = 100;
int windowH = 100;
// Define the box where we want to capture and analyse colour from
// The start point of the box (top and left coordinate)
int boxL = 633; // That's the middle of the screen
int boxT = 334;
// Size of the box
int boxW = 100;
int boxH = 100;
//How many pixels to skip while reading (the more you skip, it runs faster, but result might get worse)
int pixelSkip = 2;
// Screen Area to be captured (usually the whole screen)
Rectangle dispBounds;
// creates object from java library that lets us take screenshots
Robot bot;
void setup(){
// Create screenshot area
dispBounds = new Rectangle(new Dimension(screenW,screenH));
// Create Preview Window
size(windowW, windowH);
// Standard Robot class error check and Create screenshot Robot
try {
bot = new Robot();
}
catch (AWTException e) {
println("Robot class not supported by your system!");
exit();
}
}
void draw(){
//ARGB value of a pixel, contains sets of 8 bytes values for Alpha, Red, Green, Blue
int pixel;
int r = 0;
int g = 0;
int b = 0;
// Take screenshot
BufferedImage screenshot = bot.createScreenCapture(dispBounds);
// Pass all the ARGB values of every pixel into an array
int[] screenData = ((DataBufferInt)screenshot.getRaster().getDataBuffer()).getData();
//Find the RGB values of the region we want
for(int i = boxT; i < (boxT + boxH); i += pixelSkip){
for(int j = boxL; j < (boxL + boxW); j += pixelSkip){
pixel = screenData[ i*screenW + j ];
r += 0xff & (pixel>>16);
g += 0xff & (pixel>>8 );
b += 0xff & pixel;
}
}
// take average RGB values.
r = r / (boxH/pixelSkip * boxW/pixelSkip);
g = g / (boxH/pixelSkip * boxW/pixelSkip);
b = b / (boxH/pixelSkip * boxW/pixelSkip);
color rgb = color((short)r, (short)g, (short)b);
fill(rgb);
rect(0, 0, 100, 100);
println(frameRate);
}
