설명
Looks for the next valid integer in the incoming serial. The function terminates if it times out (see Serial.setTimeout()).
Serial.parseInt() inherits from the Stream utility class.
In particular:
-
Initial characters that are not digits or a minus sign, are skipped;
-
Parsing stops when no characters have been read for a configurable time-out value, or a non-digit is read;
-
If no valid digits were read when the time-out (see Serial.setTimeout()) occurs, 0 is returned;
