Node.jsGet serial data from Arduino.

var SerialPort = serialport.SerialPort;
var arduino = new SerialPort( '/dev/cu.usbserial-DA01L7G3', {
baudrate: 9600,
parser: serialport.parsers.readline( '\n' )
} );
arduino.on( 'data', function( data ) {
console.log( 'Count: ' + data );
} );
Watson IoTSend data to Watson IoT for distribution.
