void	begin ()
	Sets the data rate in bits per second (baud) for serial data transmission. For communicating with the computer, use one of these rates: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, or 115200. You can, however, specify other rates - for example, to communicate over pins 0 and 1 with a component that requires a particular baud rate. More...
void	begin (unsigned long baud)
	Sets the data rate in bits per second (baud) for serial data transmission. For communicating with the computer, use one of these rates: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, or 115200.

void	begin (unsigned long baud, int modeChoose)
	Sets the data rate in bits per second (baud) for serial data transmission.

virtual int	read (void)
	Reads incoming serial data. read() inherits from the Stream utility class. More...
virtual int	available (void)
	Get the number of bytes (characters) available for reading from the serial port. This is data that's already arrived and stored in the serial receive buffer (which holds 64 bytes). available() inherits from the Stream utility class. More...
virtual int	peek ()
	Returns the next byte (character) of incoming serial data without removing it from the internal serial buffer. That is, successive calls to peek() will return the same character, as will the next call to read(). peek() inherits from the Stream utility class. More...
virtual size_t	write (uint8_t c)
	Writes binary data to the serial port. This data is sent as a byte or series of bytes; to send the characters representing the digits of a number use the print() function instead. More...

write()

size_t HardwareSerial::write ( uint8_t  c )

virtual

Writes binary data to the serial port. This data is sent as a byte or series of bytes; to send the characters representing the digits of a number use the print() function instead.

Parameters

[in]

c

Specify the byte which will be sent to the console.

Returns

The length of sending to the console.

Note

Implements Print.
