Please read this first if you have a question. If you're using Pure Data Vanilla (like 0.51-3) and NOT extended, you have to download externals. Go to help -> Find externals. And search & install "comport" and "cyclone". [comport] object should show up when you type it now. cyclone externals are kinda odd since objects like [zl] and [fromsymbol] may not show up when you type it in. The solution is type [cyclone/zl group 100] and [cyclone/fromsymbol]. By the way, the substitute for [iem_alisttosym] is [list tosymbol]. You can see it clearer in this tutorial (time-stamped) kzbin.info/www/bejne/n6W0dGx9rbSSf9U

Each of your videos feels like a new horizon opening up. I never had the idea to combine PD and Arduino, but today a mindblowing perspective was preaented and I feel there is a lot to discover.

[@SoundSimulator]

Definitely, I remember learning about using Arduino with music software for the first time and a whole world opened up. I wish a video like this existed 8 years ago, so I'm glad to have made one myself! I hope that there will be people stumbling upon this video and be excited about combining Pure Data & Arduino!

[@staerkej]

You sir, are my new hero. You deserve WAY more views. I was having issues with the comport, but i just jumped to the ''Purr Data" version of Pd because it said it had all the Pd-extended stuff installed. Got everything working, but i also plan to use Daisy for embedded audio in the near future. Do you think i will run into issues using Purr Data, rather than vanilla for programming Daisy? Thanks for everything dude! I hope you continue making videos, i really enjoy them. Easy to follow, and also fun to watch.

[@SoundSimulator]

Glad to hear that you found this video helpful!! Using plugdata will be helpful when working with the Daisy since there's a compile mode that tells you which object is compatible or not. Have fun!

[@Willpowerstudios]

Hi, I'm on linux using plugdata and had to install 2 externals: iemlib + comport. I had to add the comport path manually in settings under 'Libraries to load'. It works great. I'm excited 😃

[@mudmax8974]

Man you're the best, everything went perfectly well !

[@ashaydave]

Hey, could you tell me if you had any problems? I can't seem to have my patch working correctly, probably cuz of the serial port thing. I have everything in place but when i use comport 0 9600, it tells me opening serial port 0 failed. Same for 1-4, but since my arduino uses com port 6, when I put that, it doesn't seem to change values with the knob.

[@chrisbistrishki]

Hey man! Thanks for the awesome tutorial, it helped me a lot! We're currently building an instrument for our electronics class (Sound Engineering Major) and our goal was to convert color into sound. For that we took two sensors - a photoresistor which we plan to map to a volume parameter and a color sensor which we plan to map to a frequency-dependant parameter of a synth in Pd (for example a mod. freq. of an FM synth). The thing is, the photoresistor is connected in the analog input of the Arduino and the color sensor must be connected through the diginal Ins on the arduino board. However your array seems to only work if the 2 or more sensors are analog, hence the line "val[i]=analogRead(i)". The "unpack ff" function then can't read that respectively, seemingly because the two sensors use different kinds of technologies/inputs. Are we understanding this currently and are we on the right path? Could you think of a solution where we can use the array which you demonstrated, but with one analogue and one digital sensor plus the unpack ff function in Pd. The situation is pretty hopeless at this point so we'd really appreciate your input!

[@SoundSimulator]

Nice! Feel free to share the project when you're done! As for the questions, yes, you're definitely on the right track. So you can keep the Pure Data patcher the way it is now, but you need to modify the Arduino code a bit. Use the "one sensor" code as the foundation and add the following... --- brightness = analogRead(0); //Reading the photoresistor here (connected to A0) Serial.print(brightness); //Send to Pure Data. It'll be the first outlet of the [unpack f f] Serial.print(" "); //There's a space between " & " Serial.print(color); //I'm assuming you found a code for the color sensor and this is the variable you get. Send to Pure Data... Serial.println(); //Don't forget the 'ln' here --- I hope this works! If you have any further questions, feel free to reach out via social media. Best of luck!

[@jaffasplaffa1]

Nice video. And nice channel over all. I love Pure Data and use it pretty much on a daily basis. I was messing with Arduino a few years ago. As i remember it, using delay is not good practice. The issue that the whole program is hold up until delay is over. The whole program is basically frozen until delay is processed. "Arduino - delay () function The way the delay() function works is pretty simple. It accepts a single integer (or number) argument. This number represents the time (measured in milliseconds). The program should wait until moving on to the next line of code when it encounters this function." This is not an issue for smaller projects, with just a few knobs, but as soon as you start to make something larger, it's an issue. Atm I don't remember what I used instead, but there are more "good practice" solutions, that won't cause issues down the road, as using delay might. Anyway have a good day ;)

[@SoundSimulator]

Sorry for the delay in response, but yes, delay is not good to use in the long run for sure! My professor always suggested that I stay away from it. I should do a video about this...

[@jaffasplaffa1]

​@@SoundSimulator No problem at all. I like your channel. Not a lot of people talks about these subjects. Keep it up :) Yeah, that's a good subject actually. Look forward to see it in the future ;)

[@pieterpauwelbeelaerts5995]

Nice tutorial. Explaining the breadboard also helped me, thanks! Just a quick question, is it possible to modify the light theremin project, so that the light resistor sensor replaces the potentiometer? I will try... I would love that data to become useable for virtual synths in pure data or somewhere else...

[@SoundSimulator]

Thank you very much for watching! I'm glad that this tutorial was helpful! Yes, you can follow this tutorial and use the light sensor instead of the potentiometer knob. You'll find many helpful diagrams if you google image 'light sensor arduino'. In my recent video on digital buttons, you can find a link to the resistor set that I recommend. Any resistor sets with good reviews will work tho!

[@pieterpauwelbeelaerts5995]

​@@SoundSimulator I have made the project now with an analog light resistor that was in the starter package (instead of a potentiometer), and in the program arduino I combined the light theremin code with your code for the serial writing. The program works, though it only shows numbers between 45 and 57... so that is a bit limited as a sensor reading, but a great start for a beginner like me... Maybe I have to update the analog LDR to a digital light sensor, or perhaps a voltage meter for a solar panel could work too...

[@SoundSimulator]

@@pieterpauwelbeelaerts5995 Analog photoresistor should give broader range than that. Did you make sure to use a 10k ohm resistor when connecting the sensor? We need a pull-up resistor for some sensors unlike the knob sensor we used in this video. The analog should be about 300 (average room brightness) to 1023 (light source right in front of it). Or it could be something with the Pure Data patch. If you would like to send me screenshots and such, please feel free to DM on social media or email me at hizumu.sound (gmail).

[@jeremiasescudero2524]

Thank you very much for the help, I managed to solve the problem. Now I have another problem: Arduino recognizes the COM1 port, which is where I have the board and potentiometer connected, and gives me values from 1 to 1023, which is fine. Then I open my Vanilla Pure data and the COM1 port is not recognized, it is not even in the list. (tried this with Purr Data{extended} and same error). When I close the Arduino, and open only the Pure Data, it recognizes the COM1 port, but the Arduino no longer recognizes the COM1. Connection through COM ports is not possible, since it is used for a single program, not simultaneously. Before, they could be intertwined, but by connecting and disconnecting so many times I think the port was blocked, I need to unblock the COM port and give it access so that both programs can communicate through the same COM port. I've been trying to do this experiment all day, I tried with Windows 10 but I couldn't either, I got to the same point, I've even tried with multiple versions of PurrData and PureData on Windows and MacBook. 😢 :C I visited forums but nothing, last help please :')

I bought Arduino Uno@@SoundSimulator

Figure out how to make pd run on the arduino!

[@grenadinementalo]

arduino detects my board but not pd when i clic the "devices" object, what should i do ? EDIT : just have to close the arduino ide and maybe unplug and replug the board - is there any other option ?

[@grenadinementalo]

and the zl group object could'nt create (i installed cyclone library but not sure which ont i got to install) EDIT : Had to replace "zl" by "cyclone/zl" in the object

[@SoundSimulator]

@@grenadinementalo Externals can be weird on Pure Data. You have to do [cycle/zl group 100], you can see it clearer in this video kzbin.info/www/bejne/n6W0dGx9rbSSf9U It'll directly go to the part when you click on the link! In terms of the board being recognized, I'm not sure. As long as it works (even if you need to unplug & plug), it's fine//

[@SoundSimulator]

Do you have social media like Instagram? Please feel free to send me a screenshot of the code. What Arduino are you using by the way? Unofficial (but more affordable) ones can cause lot of trouble.

[@Subzearo]

Do potentiometers hav actual + and - pins?

[@SoundSimulator]

Yes! There should be a documentation that tells you which pin is what.

Noob friendly! Thank you!

You're welcome! I'm glad that this is informative to you!

9600 is the baudrate

[@kiko2129]

Hi, Thank you for the great Video, i did it step by step but i simply can't connect the arduino with the Pure Data. I get the following error msg in Pure Data comport number 0 out of range (1-99) [comport] opening serial port 0 failed! Can you help me out here? I have the code line by line identical. Thanks and have a nice day :D

[@SoundSimulator]

That error message is fine actually. Click on the [open 1] message box and see if you're still getting an error. I put 0 in [comport 0 9600] so that serial communication doesn't happen automatically. That 0 is for stopping/closing serial communication. The [open 1] will override that 0 and the error (unless your Arduino port is not 1. In that case, click on [devices] to check).

EXE LENT ! Thanks!

Thank you so much Federico!!

[@EMERGENCIASTATE]

why this doesn't work with an LDR?

[@SoundSimulator]

Unlike knobs, LDRs/photoresistors require a pull-down resistor (10k ohm) when connecting to an Arduino. Searching "LDR Arduino" into Google Image will provide you with diagrams that you can recreate. If you did connect LDR using a resistor, then I'm not sure what the issue is. Please feel free to contact me through any of the social media listed! Good luck!!

[@EMERGENCIASTATE]

@@SoundSimulator ! tHANK YOU You roCK! Already have the resistor and connection in Arduino i got numbers like 900, 800, but in the print in Pure data, i saw 53 13 and 10 in the print. i dont see it in the number object like in the knob : /// :((

[@elRevulo]

Pd-extended is abandoned. Please use vanilla + externals or purr-data. Please don’t make new tutorials relying on extended, it’s so confusing for new users.

[@SoundSimulator]

Definitely, we'll be using vanilla + externals for future videos. I did put a comment on this video regarding externals. I hope it's showing up at the very top for everyone!! Thanks for the feedback, Felix!

[@antonioalaia6579]

Hello I'd like it because I'm new on Arduino World and I'm looking for an alternative of Max Patch. So I follow a plant play tutorial (kzbin.info/www/bejne/o6Sxn5x-Z5ensMk), I think easy, than may questions is: Can I obtain same result by PureData? If yes how do it? Thanks.!

[@SoundSimulator]

You should be able to do something similar with Pure Data for sure! I recommend starting out with this tutorial and then analyze the Arduino code in the video that you linked. Good luck!
