hi, everyone. i start learning Arduino these days. i studied the patch in tutorial "serial communication" from Max tutorials, there are something i don't quite understand:

under [serial a 9600] there is a [sel 13 10] , why are we made the [sel] send a bang every time it receive the number "13"? and why it eliminates the number "10"? according to the tutorial, "10"means linefeed and "13" means carriage return, what the difference between linefeed and carriage return ? and where are the number "10" and " 13" come from? dose they must be "10" and "13"?

a lot of questions and my english is not good,

if anyone can help me, thank you very much~~~

The [sel 13 10] is there to identify the Serial.println() output from Arduino. I can't remember the keystroke for ASCII 10, but 13 is clearly "Enter" which performs both the carriage return and linefeed.

You could of course send anything you like at the end of your Arduino sketch, for example Serial.print ("H"), and then use [select] to target that character.

The actual reason for using [select] to output a bang is to ensure that your data coming into Max is bundled into a nice package, by the [zl group] object that follows it.
