Hi all, i've programmed a rpm with arduino, how i can use the output that i have to create a realtime updated cartesian graph time/rpm.

Something like that:

Ty,
Yaro.

Send the RPM to Processing. In Processing declare the value as a variable (I used random, change this to your value from Arduino):

float rpm;
int dataNum = 600;
float[] previousRPM = new float[dataNum];
void setup() {
size(600, 200);
smooth();
}
void draw() {
// In your case this will be set to the value sent from Arduino
// Map the value to fit the size of the screen
rpm = random(height);
background(255);
previousRPM[0] = rpm;
for (int i = dataNum-2; i > 0; i--) {
previousRPM[i] = previousRPM[i-1];
line(i, height-previousRPM[i], i+1, height-previousRPM[i+1]);
}
}
