 Bigger Bigger  Smaller Smaller  Reset Reset

Hi I'm not sure if this is the correct forum to be asking this question so apoligies in advance.
                                                                                                              
I have an Adruino Uno which will be used with the "Arduino networked lamp"  from "Getting Started With Arduino" 2nd Edition.  The networked lamp circuit is assembled as I understand it the Arduino sketch takes care of the Uno & circuit while Processing sketch acts as a proxy? . I have the Processing 2.0 beta program which is required, however when i try to run the code - Example 08A: Arduino networked lamp in "Processing" i get the following message/error:-

 "serial does not run in 64-bit mode"

If it's any help I'm running both Arduino and Processing on a HP with windows 7 intel i3. I downloaded Processing both 32-bit & 64-bit versions and get the same   "serial does not run in 64-bit mode"    message on both versions 32-bit & 64-bit?

what changes and where do they need to be made to make this project work?
 
Once again I'm not sure if this is the correct forum to be asking this question so apologies in advance.
any help/advice would be greatly apprieacted as I really would like to see the LED's glow when the works "peace" "love" "arduino" are mentioned in the Makezine.com blog when I finnaly run both sketches, the old learning by doing approach, Thanks

Hello and welcome,

I did a quick search for you and it suggested to use Processing 1.5.1. Try and report if it worked smiley

Hi, yes I tried with Processing 1.5.1 and it's up and running on a USB Droid board however I'm really only half way as I'm still working out how to use Processing but Yeah making progress. Thanks for your reply, very helpful 1.5.1 worked with the OS I'm running Thanks again.    smiley
