Sending Data Back & Forth Between Arduino And Pure Data (also works with MaxMSP!)

Let’s send a sensor data to Pure Data from Arduino. And at the same time, let’s send a brightness data to an LED from Pure Data.

You are a PD god. Thank you immensely for this very helpful tutorial

[AntonSoederberg]

I'm teaching at a sound art seminar in Sweden using what I'm learning from your Youtube channel. Amazing work! You make the Internet an amazing place <3 Thank you!

Hey, huge thank you for your tutorials. This is going to be the second I follow. Your steps are flawless and pleasant to follow.

I usually go for the OSC library provided by CNMAT (on github). It allows sending OSC as SLIP encoded messages over USB. That allows as many ins and outs as you might want, with human readable addresses. It's also simple to port over to boards with wifi should you ever want to do that.

Thanks for creating such a friendly resource for new patchers 👍🌈

Keep making videos of this quality and you will get a very large following. You are helping a lot of people around the world, brother.

I was literally searching for something like this yesterday for a project, so thank you! 🙏🏽

Beautiful. I usually transfer data between arduino and PD by using Serial.write instead of Serial.println.. It has its own problems, but at least I dont need all the libraries and complicated asci decoding stuff :) but nice to see multiple methods of doing things!

[TheOleHermit]

Excellent! Been needing to retrieve frequencies from the Teensy laser synth to the controller's monitor, modify the frequency from the freq counter, then send that value back to the laser synth in real.
So far, I've only been able to display the frequencies with the Arduino IDE's serial monitor.
Also diving into TouchOSC and customizing Reaper's DAW for touch GUIs over Ethernet connected devices. Fun stuff.
Thanks!😎

That seems like an easy workaround, I think the more proper way to do it would be to use something like the Task Scheduler library on Arduino for asynchronous execution of the sending and receiving. I don't have much experience with this though and it is a pretty big step up in coding concepts.

[ZOMichael-ds]

Thanks always! I would like to know how I can use udpsend / receive in PD like MaxMSP. Can you show it to me? Thanks again!

[anacarolina]

this works with the image? if I want to put a image move?

[deltasoundlabs]

Are the values 13 and 10 specific to [comport] in Pd? Why are they specified in the [sel] object in your Pd patcher?

[TcheezSandtwich]

Hello, I've been watching and learning from your videos, they have been very useful in helping me learn the basics of PureData and Arduino, thank you so much for your tutorials !

Recently I have purchased a Daisy Seed, I've figured out how to upload code using Daisyduino for Arduino IDE, and using Visual Studio Code, but I can't for the life of me figure out how to use Daisy to control sounds in PureData. I have followed your videos demonstrating how to achieve this using Arduino UNO with success, but the same methods don't seem to work for the daisy seed. Could you possibly give me a few tips ?

The moocow externals seem to have vanished from the Internet and I can't find another way to reliably convert the data to bytes. That said, sending [print 1234 1234 1234( to [comport] is supposed to handle that parsing, so you can send arbitrary lists, symbols, or strings, but it doesn't seem to be working, either. I only ever get newline (10) at the other end, not the content of the message

I'd sure love to figure out how to just make [print *( work, but an external (or other technique) that converted to bytes would be second best.

Edit: Turns out, in MacOS, you need to confirm each *.pd_darwin file by right clicking, clicking "Open", and then telling the warning box OK. But I still get errors when I try to send anything at all.

[tannsanndforever]

I'm not able to get the pure data code to work. Two of the objects show up red and don't work. any help would be appreciated

[eliahdude]

is it possible to send max msp or puredata to a teensy and use that as a standalone synth, without ever having to connect to a computer? including knobs.

[eliyahumedia]

what is cyclone? is it a library? how do you use it in Pure Data?

[takayoshinakano]

I see "bsd_path", what should I do?
