Hello!
I'm sorry this email will be probably too amateur but I just couldn't figure out for days how to retrieve data into PD from the sensors I connect to Arduino (HC-SR04 ultrasonic sensors). I have no problem viewing them on Serial Monitor of Arduino software by some libraries I found online, though processing them at PD seems a bit tricky. I have tried SimpleMessageSystem, Firmata and Pduino but couldn't really have managed in neither of them.
All I want to do is changing different parameters (frequency, loop-time, volume etc.) of playing sounds from an existing library (just a folder with songs/sounds), thus play them *accordingly *to the data I gather from sensors (10 of them). Plus making relevant changes throughout *time*. Idea is that people dancing on a dance floor can affect the sequence of electronic music played, in a collective and sensual way. Me being only a starter at PD, also, doesn't help much either; but gotta do it for my graduation. Technically I can't really "create" music like that in this short time and it's not my interest; BUT I feel like *modifying* existing music shouldn't be a big deal. No?
Any suggestions? Highly appreciated! Thank you all!! Emin
Do you use a special library in Arduino to get data from your sensors? If not Firmata + Pduino should work just fine. Are you sure you opened the right port in Pduino? Did you configure the analog pins your sensors are connected to as analog inputs in Pduino? If you're not familiar at all with Pduino I suggest you try it with more simple stuff (like push buttons and pots).
Cheers,
Pierre.

Hi Pierre,
Thank you very much for your tips. Yes I have been trying but how would I configure the analog pins as analog inputs at Pduino? I'm trying with ultrasonic sensors to read data (which is not on/off). And have uploaded the StandardFirmata code besides my sensors reading code to Arduino. And testing on the arduino-test.pd sketch on PD. Ain't working :(

First you need to make sure the electronic part is working fine (using Arduino IDE's serial monitor). Then upload Firmata. If your sensors need no special library you should upload Firmata only. Then open arduino-test.pd with your board plugged in. The first thing you want to check in Pd is whether the right port is open. Choose a port, and click on the "Version" or "Firmware" messages to see if Pd recognizes the Arduino. If it does you should see a "Firmata something" below [pd device info]. If nothing appears, change the port and try again. Once you've made sure that the right port is open, use the pink matrix in the upper right corner to open the pins your sensors are connected to. The digital pins are from 2 to 13 if i'm not mistaken, the rest is analog. Check "input" to open a digital pin for input, and "analog" to open an analog pin for input.

Hej Pierre, thanks again.
It works perfectly at Arduino Serial Monitor; all 4 sensors that are connected to.
Should I only upload the firmata library and not write any code besides for the sensors you mean? I have uploaded the whole StandardFirmata.ino example file. But you mean only *firmata library* +* sensors library* (there is one) + *sensors code* will be sufficient?
I would say let's simplify it. Let's have 4 different channels of music (sound files) w're playing. We wanna change the frequency of them *by the data gathered from 4 sensors. *Will need to put +5000 to the number we get for us to actually hear the frequency, but let's say. Or I'm fine to just "see" the analog data on PD as well. How would we do that? I send you the screenshots of how I adjusted PD... Ah, should I be seeing the numbers from sensors at the main PD window?? I get here this:

Are you using this code : http://www.arduino.cc/en/Tutorial/UltrasoundSensor ?
Apparently Ultrasound sensors need to use a single pin as both input and output (to send a pulse and to receive the echo). Unfortunately i don't think Firmata can do that (it should be possible but I suspect there would be some latency when switching from input to ouput back and forth - somebody confirm this??).
If you only need these 4 sensors, you can adapt the example code for ultrasound sensors to output the data, and read it using [comport] in Pd. This object is at the core of Pduino.
(You shouldn't see anything in Pd console when using Pduino, except information about the current connection and the device.)

Nop! Another sensor - HC-SR04 which uses 2 pins: *Echo and Trigger - *input and output. I use this code at Arduino to get it working. For each pin, I rewrite the same code only changing the (10, 11) at the third line. It gives me inch as distance:
#include <Ultrasonic.h> { Ultrasonic ultrasonic(10, 11 ); float inMsec; long microsec = ultrasonic.timing(); inMsec = ultrasonic.convert(microsec, Ultrasonic::IN); Serial.println(inMsec); delay(400); }
What do you think? Maybe we just try with one sensor and try to change the frequency of a song played at PD with it??

It would be easier if you sent only the integer value:
#include <Ultrasonic.h>
{ Ultrasonic ultrasonic(10, 11 ); long microsec = ultrasonic.timing(); Serial.write(microsec, sizeof(long));
delay(400); }
And in Pd collect groups of four characters from [comport] and reassemble them into long integers... Easiest is to send only a single byte per sensor. But you'll also need a way to determine which is the first character in the packet.

I would say let's simplify it. Let's have 4 different channels of music (sound files) w're playing. We wanna change the frequency of them by the data gathered from 4 sensors. Will need to put +5000 to the number we get for us to actually hear the frequency, but let's say. Or I'm fine to just "see" the analog data on PD as well. How would we do that? I send you the screenshots of how I adjusted PD... Ah, should I be seeing the numbers from sensors at the main PD window?? I get here this:

Then open arduino-test.pd with your board plugged in. The first thing you want to check in Pd is whether the right port is open. Choose a port, and click on the "Version" or "Firmware" messages to see if Pd recognizes the Arduino. If it does you should see a "Firmata something" below [pd device info]. If nothing appears, change the port and try again.
Once you've made sure that the right port is open, use the pink matrix in the upper right corner to open the pins your sensors are connected to. The digital pins are from 2 to 13 if i'm not mistaken, the rest is analog. Check "input" to open a digital pin for input, and "analog" to open an analog pin for input.

Hi Pierre, Thank you very much for your tips. Yes I have been trying but how would I configure the analog pins as analog inputs at Pduino? I'm trying with ultrasonic sensors to read data (which is not on/off). And have uploaded the StandardFirmata code besides my sensors reading code to Arduino. And testing on the arduino-test.pd sketch on PD. Ain't working :(
Cheers...

If you're not familiar at all with Pduino I suggest you try it with more simple stuff (like push buttons and pots).
Cheers,
Pierre.

Hello! I'm sorry this email will be probably too amateur but I just couldn't figure out for days how to retrieve data into PD from the sensors I connect to Arduino (HC-SR04 ultrasonic sensors). I have no problem viewing them on Serial Monitor of Arduino software by some libraries I found online, though processing them at PD seems a bit tricky. I have tried SimpleMessageSystem, Firmata and Pduino but couldn't really have managed in neither of them.
All I want to do is changing different parameters (frequency, loop-time, volume etc.) of playing sounds from an existing library (just a folder with songs/sounds), thus play them accordingly to the data I gather from sensors (10 of them). Plus making relevant changes throughout time. Idea is that people dancing on a dance floor can affect the sequence of electronic music played, in a collective and sensual way. Me being only a starter at PD, also, doesn't help much either; but gotta do it for my graduation. Technically I can't really "create" music like that in this short time and it's not my interest; BUT I feel like modifying existing music shouldn't be a big deal. No?
Any suggestions? Highly appreciated! Thank you all!!Emin

Thanks Martin. Hmm, do you think it really matters Martin? I already only get numbers from Arduino each sensor separately, which should just work fine, right? I mean so long as I get them in a number box each at PD.
You have any idea how to change the byte rate to 9600 at PD?

It would be easier if you sent only the integer value:
#include <Ultrasonic.h> { Ultrasonic ultrasonic(10, 11 ); long microsec = ultrasonic.timing(); Serial.write(microsec, sizeof(long)); delay(400); }
And in Pd collect groups of four characters from [comport] and reassemble them into long integers... Easiest is to send only a single byte per sensor. But you'll also need a way to determine which is the first character in the packet.

Nop! Another sensor - HC-SR04 which uses 2 pins: *Echo and Trigger - *input and output. I use this code at Arduino to get it working. For each pin, I rewrite the same code only changing the (10, 11) at the third line. It gives me inch as distance:
#include <Ultrasonic.h> { Ultrasonic ultrasonic(10, 11 ); float inMsec; long microsec = ultrasonic.timing(); inMsec = ultrasonic.convert(microsec, Ultrasonic::IN); Serial.println(inMsec); delay(400); }
What do you think? Maybe we just try with one sensor and try to change the frequency of a song played at PD with it??

Apparently Ultrasound sensors need to use a single pin as both input and output (to send a pulse and to receive the echo). Unfortunately i don't think Firmata can do that (it should be possible but I suspect there would be some latency when switching from input to ouput back and forth - somebody confirm this??).
If you only need these 4 sensors, you can adapt the example code for ultrasound sensors to output the data, and read it using [comport] in Pd. This object is at the core of Pduino.
(You shouldn't see anything in Pd console when using Pduino, except information about the current connection and the device.)
