Hi all,
I need to send fro pure data to an arduino a signal to light up a led.
How can I do that?

Yeah, yeah, I know pure data and I work a lot with it, Maybe I wasn't that clear, I would like to have an entire OS based on puredata to run on a standalone device like this:

If you are familiar with eurorack you know what I'm talking about, since is one of the fanciest (and most expensive) modules out there.

Goodevening to all the nerds out there!
Let's start saying I'm not much more than a complete noob on programming.
I'm starting to think about a sort of "tape machine" based on pure data. Hardware speaking everything should run on a Raspberry Pi.
I would like to know if it would be possible and how hard it would be to create a custom operative system and GUI for it based on pd. For example I would like to have a sort of 3 page menu.

1. Displaying just the array that content the sample.
2. A load/save page for the samples.
3. A sort of effect page and sample edit.

Thank you!

The solution that Theorix suggest was simple and effective thanks a lot!

Hi! I was thinking about using line, but it's not clear how to use it to smooth some continues incoming values.

I'm receiving datas from some encoders, but they are too fast and sometimes I end up with the sliders jumping back and forth resulting in some unwanted clicks. There is a way to Smooth the transition from a value to another? using a buffer or something similar?

Nope, the raspberry will run headless but now i'm configuring it with a monitor a a basic desktop environment.
Yep, dsp on, not from the patch but from the media menu.
Yep, I know that link. and it's configured correctly as far as i understand it. The audio is forced trough the 3,5 jack.
Nope, I can't hear anything trough the 3,5 jack even the most light noise, I can't even hear any "short" noise when i Plug or unplug the headphones, it's like the output it completely unconnected7unpowered.

amixer cset numid=3 1

yep, still no sound.

@whale-av Hey! Thank you for the link but I need to run pure data on a headless raspberry and I need the audio out from the 3,5 jack.

Hi all!
Pure data on the Raspberry doesn't output any kind of sound. I'm using the alsa drivers, How should I set it up correctly?
