[Serial]
描述
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().
語法
Serial.println(val)Serial.println(val, format)
參數
val: the value to print – any data typeformat: specifies the number base (for integral data types) or number of decimal places (for floating point types)
回傳
size_t (long): println() returns the number of bytes written, though reading that number is optional
範例
/*
Analog input
reads an analog input on analog in 0, prints the value out.

*/
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
// delay 10 milliseconds before the next reading:
delay(10);
