I was wondering if anyone has modeled any of the [arduino] examples/ tutorials relating to PWM and tone production with the [arduino] object? (I am referring to the examples/tutorials that come with the software or on their website, like "multi-tone")

I have been playing with composing some small things by just sending numbers to the arduino (using the processing/arduino language) and having it output tones through the digital pins, but what would be great is to be able to dynamically send it midi or other control information and have it update information regarding frequency or density

unfortunately I cannot see how to do this with the [arduino] object, so if anyone has any ideas/examples/suggestions, I am very interested...

it could also be useful, as mentioned above, to see what it would look like to model some of the example sketches from the arduino website or included with the software in pd....but maybe it is unlikely anyone has done this..I realize the concept of the languages is somewhere totally different (but that is the advantage, right?)

Did you check pduino or arduino in the search engine?

yes, of course I checked searched first and checked the examples. I have pduino and have been using it for a while. Actually, my question is regarding pduino...whether one could in fact give that object dynamic input to drive changing output values from the arduino.

Many people are using it in the opposite way..the arduino processes sensor data and this is sent to a program to do something. It seemed like nearly all posts I saw were regarding this.

I am trying to send the chip changing data and have it output sounds directly, so its actually more similar to what people are doing when they use the arduino to control servo motors.

The reason I want to know about this is because if I could send the [arduino] object changing values dynamically, it would mean that I would not have to try to write the sketch in processing to manage a lot of variables and incoming osc data. I know how to manage the numbers in pd, but not so much in processing.

so then the question is, can you send the arduino numbers through the pd [arduino] object and get changing outputs..for example change the values in the tone and multi-tone examples...? because otherwise if you want to change frequency or duration values from an incoming OSC stream you have to write a pretty complex processing patch (if you have a whole lot of tones being generated)

hopefully that clarifies the question, usually adding words doesn't but I am trying to explain...

wow, ok, this looks like it might provide a solution...but I can't test it until tomorrow. not sure how I didnt see it before. but yes, changing input values...

Have you looked at Bitlash for the Arduino?
http://bitlash.net/

Bitlash looks interesting, thanks, I am looking through the pdf now...

I managed to get the serial port working both ways with the [Arduino] object (note the capital A - its a different object) and processing sketch that at http://www.lourensrozema.nl/index.php/a … redata.inc
it was tricky...but it works so far. But all I am doing is sending signals back and forth, I havent figured out how to actually use it to do what I want yet....

I will check this Bitlash stuff more deeply, thanks for the suggestion.
