Thanks Andy R

So my understanding then is from processing you can only pass variables that arduino needs to absorb and determine actions.
There is no way to call methods directly then? Would be a nice to have feature i guess, but the variable passing is acceptable.

any thought?

[Arduino]

let me clarify

the though was for processing to do some variable and config stuff.
then using the arduino.cc class and firmata on the chip be able to upload a sketch to processing.

with the answer provided above. a different approach is required.

I have played around with a blink on roll over sketch using processing and firmata to set HIGH or LOW the pin 13 LED.
In all the reference to the arduino library for processing i have not seen any instance where i can call a method that i have create on the arduino side.

let me describe

Arduino

Code:

// firmata included
void setup(){}
void loop(){}
void customMethod(){}

Processing

Code:

/*
 some code ommited
*/
import processing.serial.*;
import cc.arduino.*;

Serial port;
Arduino arduino;

void setup()
{
   arduino = new Arduino(this, Arduino.list()[0], 57600);
}

void draw()
{
  background(#000000);
  fill(#000000);
  rect(0,0,200,200);
}

void mousePressed()
{
  /*
    i want to fire off a method called customMethod in the arduino code
    this doesn't work
  */

   arduino.customMethod();
}

This is the snippet i would like to work

void mousePressed()
{
  /*
    i want to fire off a method called customMethod in the arduino code
    this doesn't work
  */

   arduino.customMethod();
}

can this be done?

Is it possible to upload a sketch via processing?

Code:

client.print("<META HTTP-EQUIV=REFRESH content=5 url='http;//192.168.1.110' >");

replace the ; with a :
client.print("<META HTTP-EQUIV=REFRESH content=5 url='http://192.168.1.110' >");

for this size of board you can easily use only 1 mounting screw

great write up mowcius!
great site as well http://www.duinoaday.co.uk/ <- bookmarked
my apologies for providing a how to smd list. didn't realize you already knew how!

for getting the old SMD LEDs off, or any SMD 0805 things like resistors and diodes i would recommend getting a pair of hot tweezers.
they are pretty easy to solder on.

1. clean the pads
2. use flux on both pads
3. put a very small amount of solder on one pad
4. grab the SMD with needle tweezers
5. align it on the pads
6. heat the pad you presoldered in step 3 and slip the SMD in
7. solder the other side
8. enjoy the fruits and colors of your labor

SMD can go on perfboards as well!


and they are dirt cheap if you buy in bulk from ebay
i bought a 100pcs mix pack (white, yellow, purple, cyan, red, green, blue)

Hey all
This isn't anything super duper fantastic.

but last night, i finished soldering up one of my projects and had some 0805 LEDs left over...   ...so i decided to change the lights on my Arduino board

Power = Blue
Pin 13 = Blue
TX = Green
RX = Red

enjoy

take a look here http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1285690460/ and here http://sparky.32teeth.org
may be able to answer some questions for you

[pwillard]

picked one up (live a block away from an electronics shop)
confirmed! all works well!

thanks again pwillard

thank you kindly
picking one up today

this is the tutorial i was referencing
simple connection test

http://arduino.cc/en/Reference/ClientConstructor

in which they don't use the subnet and gateway?

the shield itself is the official arduino one with W5100
http://www.arduino.cc/en/Main/ArduinoEthernetShield

i have tried the above code with the subnet and gateway, but i don't believe that my issue is
the arduino side of things but rather my network setup at home

to clarify
my pc has a onboard wifi which i use for connecting to my connection and the arduino shield i have attempted to use the rj45 (do i need a crossover?)
additionally i have turned on my telnet in vista

Hey all
i just purchased an authentic ethernet shield for the arduino

i have followed several tutorials to the t and have not been able to get the arduino ethernet shield to connect

here are the only lines i changed from the example code for ethernet client

Code:

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 192, 168, 1, 103 }; // local address for ethernet shield
byte server[] = { 66, 249, 91, 104 }; // Google - ping as of June 6 2010

the serial response

Code:

connecting...
connection failed

disconnecting.

i have tried assigning different IPs for the shield

my setup
1. linksys wrt54g (in another room)
2. vista 32
3. arduino 0018
4. ethernet shield (rj45) connected to the ethernet on pc
5. pc is using wireless for connection to router

i am stuck, and would appreciate any help
