This command takes the same forms as Serial.print(): Serial.println(b) prints b as a decimal number in an ASCII string followed by a carriage return and a linefeed. Serial.println(b, DEC) prints b as a decimal number in an ASCII string followed by a carriage return and a linefeed. Serial.println(b, HEX) prints b as a hexadecimal number in an ASCII string followed by a carriage return and a linefeed. Serial.println(b, OCT) prints b as an octal number in an ASCII string followed by a carriage return and a linefeed. Serial.println(b, BIN) prints b as a binary number in an ASCII string followed by a carriage return and a linefeed. Serial.print(b, BYTE) prints b as a single byte followed by a carriage return and a linefeed. Serial.println(str) if str is a string or an array of chars, prints str an ASCII string. Serial.println() just prints a carriage return and a linefeed. Parameter data types: integer types, including char, strings (char arrays) & floatsPrinting of floats is supported with a precision of two places to the right of the decimal point.This may change soon. 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); } Programming Tip / Known Issues see Serial.print See also ASCII chart Serial.begin(speed) Serial.available() Serial.read() Serial.print(data) Reference Home Edit Page | Page History | Printable View | All Recent Site Changes
