Playing a video through Arduino
Hello All
I hope that I won't offend anyone with my very beginner question.
I have 4 video animations relating to 4 arduino buttons and my interaction will be playing one of the videos once it's corresponding button is pushed..
Can anyone help me how to make it work? I'm really new to Max and I could not find help on my own.
Thank you so much in advance!
Hi
how far have you got with this project? Have you got one of your videos playing in Max yet? Do you have button data coming into Max?

Hello Sir,
Yes I was able to play just one video when I push the button connected to the Arduino.
Now, I'm stuck with reading the 4 buttons and making each one trigger the corresponding video.
Thank you so much for your concern.
Hi
good work. In order to identify which button is pressed you need to send the 4 buttons *in order*, and in groups of four. In Arduino you would write something like:
. . . .
Serial.print(btn1);
Serial.print(" ");// a space
Serial.print(btn2);
Serial.print(" ");// a space
Serial.print(btn3);
Serial.print(" ");// a space
Serial.println(btn4);// bundle terminates with carriage return and linefeed (ASCII 13 10)
Then in Max after your [serial] object, put:
[select 13 10] - this looks for the 13 10 from Arduino
(the left and right outputs BOTH go into the next object, which is . . .
[zl group 200]
[itoa]
[fromsymbol]
[unpack 0 0 0 0]// this object will output the individual button presses
Using the forum's search function above, I came up with this:

And the interwebz offered this:

Good luck
Thank you so much Sir :) very helpful
Just out of curiosity, do you take freelancing work? and if so, can I take your email so that we can discuss it?
ps
[zl group 200] is overkill; [zl group 10] will work too, doesn't make any difference in performance. It simply packs the streaming data into a list, but is commonly valuable only when reading dynamic, constantly changing values (from pots, force-sensors etc)
What kind of freelance work? I'm self-employed and working part-time in the local Universities, as a lecturer in DIY digital instrument design and inclusive creative technologies. Don't be TOO impressed. I learned pretty much all I know from this forum and a few others. Hang in there dude!!

An alternative method, which might be more transparent, is to do the following: in Arduino give each switch a unique header (or name), and then look for that header in Max. Note that this requires the use of Serial.write, instead of Serial.print and Serial.println.
. . . .
Serial.write("1");// ASCII 49
Serial.write(btn1);// 1st button state (pressed?), sent as a single byte
Serial.write("2");// ASCII 50
Serial.write(btn2);// 2nd button state
. . . .
In Max, after the [serial] object connect:
[zl group 2]//puts header + value together
[route 49 50]//looks for the ASCII code for number 1, 2 etc
This will output discrete values at the right and middle outlets of [route]. No need for ASCII conversion with [fromsymbol] and no need for carriage return and line feed.
HTH
I'm really sorry but for me all you are talking about is more of rocket science to me!!
I have just started working with Max 3 days ago and I can't even apply what you are telling to me.
I searched for a while and I have found out this Patch: Arduino2max
http://playground.arduino.cc/Interfacing/MaxMSP
That works like charm but only on Macintosh, I tried to get it to work on my Pc but it does not even recognize the serial port.
Hi Omar, try to stay away from all that Arduino2Max, maxuinos and similar.
You must understand what arduino sends and what max needs to
do to output received data into something usable.
If You get nothing out from Max on PC, but do get data on Mac,
using same patch, then PC is not seeing Arduino.
Probably due to missing driver...
If You want help, You must post details, what arduino,
what OS, Max version etc.
Only so one can give some help.
In Arduino, look under Tools/Board and Port. On Mac it will be similar to:
dev/tty/xxxx. In Max send the [serial] object a "print" message causing it to list the available COM(tty) ports in the Max debug window. Now change the name of the serial object to, for example [serial c] or [serial b] as necessary.
Do the same thing on PC but the Arduino will be called COM2 or COM3 . . .
I think this is your first challenge, then take it from there. As Source Audio suggests, stay away from Arduino2Max, ArduinoSMS, Maxuino etc UNTIL you know what you are doing.
