dear

Each note has to have a "duration". In your code you are turning on and of the speaker just once. this produces the click you hear. You need to loop that click multiple times in order for it to become an audible sound.

look at the Arduino Developers mailing list
Bjorn Hartmann published a modified version that supports UDP

i've done it
the only thing is that the data comes back to arduino when it's not connected to the computer... if the computer is
connected the arduino "Serial" port is busy talking to it.


there are two ways...
1 send the escape code to switch to command mode... send inquiry... collect the data.. send the escape again
(now you're back in contact with the comp) and send the data back to the computer.

2 display the data on an lcd display on the arduino.

Hello

It has been retired. we might release a new version in the future

thanks for the kind words smiley

Your question is not in line with the Arduino spirit....  smiley-wink
You should be the one who figures that out, we can help u along the way.


We dont do your job for you for free but if you really need that done you can hire us

Hello

Quartz composer is not so great in terms of inputs and has practically no outputs (apart from the screen)

You can use a midi interface and connect arduino to it, QC will read midi notes...
you can hack a mouse or a keyboard and use arduino to simulate key presses..

to send data to arduino there are not many options, I've just made a QC to DMX interface but it's not super fast.

The other option is to learn how to program with Objective C and build a wrapper around the QC engine, with this you can interface it to anything

this should happen only if you have the arduino connected to a machine and the flash files server from another.
This triggers the request usually. there is a way to run a policy file server.

this should be useful

if the arduino is connected to the same computer that's serving the swf files then there is something wrong with your configuration

Hello

Thanks for the article, it's a very useful contribution.

I would encourage anybody who is contributing to the playground to add their name at the beginning of the page and possibily an email address.
I believe you all deserve to be credited for the contribution you make to Arduino and the playground needs to reflect the hard work a lot of you do.

thanks

use the serproxy provided on the arduino software page , it has a few improvements

71  Forum 2005-2010 (read only) / Interfacing / Re: serproxy crashes on: May 25, 2008, 03:12:01 am
look in the configuration file, there is a "timeout" parameter.
if there is no activity for x amount of seconds it disconnects.

the default value is 300, you might want to expand it a bit or wait until I release the new
version where the timeout can be disabled

AFAIK eyesweb has an rs232 module

if that works then arduino can work with eyesweb


i havent seen any tutorial yet, maybe because they cant keep eyesweb running without crashing long enough to write one smiley

without making it too complicated you can
wire up the buttons to the analogue inputs as usual then you use analogRead to check the state.

if you use pull up resistors your buttons will go low when pressed. this can be detected by saying


if (analogRead(0) < 100) {
//button pressed

}

You can buy them online at vinculum.com


look at the playground and you'll find some examples of a data logger already done.

hello

look at the software page on the arduino site
there is a software called serialproxy
it's bi-directional and quite solid

in a few days I hope to release some improvements I have made for a client.
