<p>Prints a data to the serial port, 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 <a class='wikilink' href='Serial_Print.html'>Serial.print</a>():

</p>

<p class='vspace'></p><p><strong>Serial.println(b)</strong>

prints b as a decimal number in an ASCII string followed by a carriage return and a linefeed.

</p>

<p class='vspace'></p><p><strong>Serial.println(b, DEC)</strong>

prints b as a decimal number in an ASCII string followed by a carriage return and a linefeed.

</p>

<p class='vspace'></p><p><strong>Serial.println(b, HEX)</strong>

prints b as a hexadecimal number in an ASCII string followed by a carriage return and a linefeed.

</p>

<p class='vspace'></p><p><strong>Serial.println(b, OCT)</strong>

prints b as an octal number in an ASCII string followed by a carriage return and a linefeed.

</p>

<p class='vspace'></p><p><strong>Serial.println(b, BIN)</strong>

prints b as a binary number in an ASCII string followed by a carriage return and a linefeed.

</p>

<p class='vspace'></p><p><strong>Serial.print(b, BYTE)</strong>

prints b as a single byte followed by a carriage return and a linefeed.

</p>

<p class='vspace'></p><p><strong>Serial.println(str)</strong>

if str is a string or an array of chars, prints str an ASCII string.

</p>

<p class='vspace'></p><p><strong>Serial.println()</strong>

just prints a carriage return and a linefeed.

</p>

<p class='vspace'></p><h4>Parameter</h4>

<p>data types: integer types, including char, strings (char arrays) & floats<br />Printing of floats is supported with a precision of two places to the right of the decimal point.<br />This may change soon.

</p>

<p class='vspace'></p><h4>Returns</h4>

<p>None

Analog input

reads an analog input on analog in 0, prints the value out.

int analogValue = 0; // variable to hold the analog value

110

111

// print it out in many formats:

112

Serial.println(analogValue); // print as an ASCII-encoded decimal

113

Serial.println(analogValue, DEC); // print as an ASCII-encoded decimal

114

Serial.println(analogValue, HEX); // print as an ASCII-encoded hexadecimal

115

Serial.println(analogValue, OCT); // print as an ASCII-encoded octal

116

Serial.println(analogValue, BIN); // print as an ASCII-encoded binary

117

Serial.println(analogValue, BYTE); // print as a raw byte value

118

119

// delay 10 milliseconds before the next reading:

120

delay(10);
