## SoftwareSerial: write(data)

#### Description

Prints data to the transmit pin of the software serial port as raw bytes. Works the same as the Serial.write() function.

#### Parameters

Serial.write() for details

#### Returns

byte
write() will return the number of bytes written, though reading that number is optional

#### Example

SoftwareSerial mySerial(10, 11);
void setup()
{
mySerial.begin(9600);
}
void loop()
{
mySerial.write(45); // send a byte with the value 45
int bytesSent = mySerial.write(“hello”); //send the string “hello” and return the length of the string.
}
