To make my application, I decided to use Processing because I'm thinking of getting to know java a bit deeper and this skill will be useful (I hope that I won't drop it a couple of days later). It was a good surprise for me that Processing PDE interface was similar to Arduino IDE and that's not a coincidense because Arduino inherited it during development. So, I took my sketch for input device assignment (pre-evaluation edition, you have to push the button there to see that site) and a pcb with a hand attached to it and started looking for examples.
import processing.serial.*;
Serial port;
float capacity = 0;
void setup()
{
size(300,300);
port = new Serial(this, "COM26", 9600);
port.bufferUntil('\n');
textSize(20);
}
void draw()
{ if (capacity>400){
background(0,0,capacity);
println(capacity);
text("Somebody touched me! 0_0 ",25,120);
text(capacity,100,200);}
else
{
background(0,0,capacity);
println(capacity);
text("Sleeping, zzz ",75,120);
text(capacity,100,200);}
}
void serialEvent (Serial port)
{
capacity = float(port.readStringUntil('\n'))/1024*255;
}
