Hi,
If you've created some cool art or something slightly different - or totally different - with what you've learned in Processing & Arduino in Tandem, we'd love to hear about it. Please post your screenshots and descriptions of what you've done with what you've learned, and let us know if it's okay to use it for a public email or post about the course.

Thank you!

Here's my creation. I wanted to create an effect of paint dripping down a canvas, plus have more "psychedelic" colors. So I added some code that randomly changes the color every 10 times we call recordLine:

CODE

if (switchHue == 0) {
randomHue = random(255);
lineHue = (lineHue * randomHue) % 255;
switchHue = 10;
}
switchHue--;

and then added some code to transform only the Y coordinate in the downward direction:

CODE

for(int k=0; k<totalVectors; k++) {
int whichVector = k % 25;
float transform = 0;
switch (whichVector) {
case 0: transform = 1.000; break;
case 1: transform = 1.002; break;
case 2: transform = 1.003; break;
case 3: transform = 1.004; break;
default: transform = 1.000; break;
}

//vectorArrayX[k] *=transform;
vectorArrayY[k] *=transform;

I've attached a screenshot. This is so much fun!

Thanks Elisabeth, really fun. Another quick way to change color is to increment the color properties.

CODE

// pseudo-code:

int h = 0; //hue

void draw() {
colorMode(HSB);
h++;
if (h>255) h=0;
stroke(h,255,255);
line(pmouseX, pmouseY, mouseX, mouseY);
}

They're written in fairly easy-to-follow instructions so beginners can give them a try. My website offers other information about crochet as well.

you can't save them to your computer, only on disney create. however, you can can record it (free) on hypercam .
