The readline() function will read all bytes until a newline character is detected. If we just printed what we received we would see b’Hello from Arduino!\r\n’. You receive bytes when you read from Serial, and you have to convert (decode) those bytes into the appropriate data type. ...

You can use the following statement to discard all data in the receive buffer: while(Serial.read() >= 0) ; // flush the receive buffer Serial.write and Serial.print do not block. Earlier code would wait until all characters were sent before returning. From 1.0, characters sent using ...
