parseInt()
Description
parseInt() returns the first valid (long) integer number from the serial buffer. Characters that are not integers (or the minus sign) are skipped.
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;
I am very new to Arduino Programming. I am trying to identify the input string from serial monitor and printing the output to the console accordingly Code is: void setup Serial.begi. Arduino Serial Communication, Bytes, Bases, and ASCII Characters November 30, 2012 by Jeff Understanding data types is especially important if you wish to use serial communication to send data to your Arduino and have the ATmega328 act on this data.
Serial.parseInt() inherits from the Stream utility class.
ParseInt returns the first valid (long) integer number from the serial buffer. Characters that are not integers (or the minus sign) are skipped. 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.

Arduino How To Read An Integer From Serial
String to Integer conversion
Reads a serial input string until it sees a newline, then converts the string
to a number if the characters are digits.
The circuit:
