I have a arduino sending serial data as printing ( printline)

arduino sends a number '400' and several caracters "a" "c" "d"

how ever in max I only recive the number 400

How Can I make it so max can read the caracters then do a bang

void loop(){
Serial.println("a");
delay(1000);
Serial.println("400");
delay(1000);
Serial.println("c");
delay(1000);
Serial.println("d");
delay(1000);

just a quick glance at your code. in our subpatch everything passes thru a int # box (numbers and letters), so in your main patch you'll never see a letter since it will never get past this point.

Agreed - the int box after the fromsymbol is killing any chance you have of a useful alpha output. Also, it's kind of hard to tell what you are shooting for with the [sel 95 10 13] at the front, but that has the potential of blowing a lot of bangs into that first zl group (given the use of Serial.println in your Arduino code).

Check out the Arduino Communications example named SerialCallResponseASCII. The corresponding max patch is below (unfortunately Max5 examples are still in the "long form" of json in the .pde, trying to change that). This may give you an idea of how to get reliable ascii messages to/from the computer
