hI,

Currently m want to operate relay by arduino board,

just i found this code to operate relay or get output by help of firmata.

i gat below mention code to operate/to get output from pin.

just i want to know how to add ASCII code to this program? meant instead of mouse i want to operate relay by pressing key like "A" for on and "a" for off.

import processing.serial.*;

import cc.arduino.*;

Arduino arduino;

color off = color(4, 79, 111);

color on = color(84, 145, 158);

int[] values = { Arduino.LOW, Arduino.LOW, Arduino.LOW, Arduino.LOW,

Arduino.LOW, Arduino.LOW, Arduino.LOW, Arduino.LOW, Arduino.LOW,

Arduino.LOW, Arduino.LOW, Arduino.LOW, Arduino.LOW, Arduino.LOW };

void setup() {

size(470, 200);



println(Arduino.list());

arduino = new Arduino(this, Arduino.list()[0], 57600);



for (int i = 0; i <= 13; i++)

arduino.pinMode(i, Arduino.OUTPUT);

}

void draw() {

background(off);

stroke(on);



for (int i = 0; i <= 13; i++) {

if (values[i] == Arduino.HIGH)

fill(on);

else

fill(off);



rect(420 - i * 30, 30, 20, 20);

}

}

void mousePressed()

{

int pin = (450 - mouseX) / 30;



if (values[pin] == Arduino.LOW) {

arduino.digitalWrite(pin, Arduino.HIGH);

values[pin] = Arduino.HIGH;

} else {

arduino.digitalWrite(pin, Arduino.LOW);

values[pin] = Arduino.LOW;

}

}

Errors...

Hi to all,

Just m trying to operate relay Relay via pc with the help of keyboard,

means i want to on relay when i press "A" and off to relay when i press "a" key,

but after downloading processing i got following error(Arduibo Firmata).

with version (processing-2.0b8-windows64)

error: processing.app.SketchException: serial does not run in 64-bit mode.

at processing.mode.java.runner.Runner.<init>(Runner.java:104)

Any of these version are not working ...

please help me to solve these problem.
