Aug 08, 2011 A Better Serial.print For Arduino Posted on August 8, 2011 by David Pankhurst In a previous article I described how to add the old-fashioned print function to Arduino to improve debugging – after all, it gets tedious to use a separate Serial.print function for each type – and inserting information into a string is printf’s specialty.
Description
Prints data to the serial port as human-readable ASCII text. This command can take many forms. Numbers are printed using an ASCII character for each digit. Floats are similarly printed as ASCII digits, defaulting to two decimal places. Bytes are sent as a single character. Characters and strings are sent as is. For example-
2.
Serial Print Values List
An optional second parameter specifies the base (format) to use; permitted values are
BIN(binary, or base 2) , OCT(octal, or base 8) , DEC(decimal, or base 10) , HEX(hexadecimal, or base 16) . For floating point numbers, this parameter specifies the number of decimal places to use. For example-
You can pass flash-memory based strings to
Serial.print() by wrapping them with F(). For example:
To send data without conversion to its representation as characters, use Serial.write().
SyntaxParametersSerial : serial port object. See the list of available serial ports for each board on the Serial main page.val : the value to print. Allowed data types: any data type.
'Reason' is a science fiction short story by American writer Isaac Asimov, first published in the April 1941 issue of Astounding Science Fiction and collected in I, Robot (1950), The Complete Robot (1982), and Robot Visions (1990). It is part of Asimov's Robot series, and was the second of Asimov's positronic robot stories to see publication. Created Date: 9/28/2011 6:43:13 PM. Isaac asimov reason pdf.

Description
Prints data to the serial port as human-readable ASCII text followed by a carriage return character (ASCII 13, or 'r') and a newline character (ASCII 10, or 'n'). This command takes the same forms as Serial.print().
