Serial
println()
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().
Syntax
Serial.println(val) Serial.println(val, format)
Parameters
val: the value to print - any data type
format: specifies the number base (for integral data types) or number of decimal places (for floating point types)
Returns
None
Example:
/*
Analog input
reads an analog input on analog in 0, prints the value out.
created 24 March 2006
by Tom Igoe
*/
int analogValue = 0; // variable to hold the analog value
void setup() {
// open the serial port at 9600 bps:
Serial.begin(9600);
}
void loop() {
// read the analog input on pin 0:
analogValue = analogRead(0);
// print it out in many formats:
Serial.println(analogValue); // print as an ASCII-encoded decimal
Serial.println(analogValue, DEC); // print as an ASCII-encoded decimal
Serial.println(analogValue, HEX); // print as an ASCII-encoded hexadecimal
Serial.println(analogValue, OCT); // print as an ASCII-encoded octal
Serial.println(analogValue, BIN); // print as an ASCII-encoded binary
Serial.println(analogValue, BYTE); // print as a raw byte value
// delay 10 milliseconds before the next reading:
delay(10);
