sendValueFromArduinoToProcessing

/* PROCESSING CODE

/**
 * Example sketch for the SerialRecord library for Processing.
 *
 * Receives an integer from the serial port, and uses it to control the
 * horizontal positon of a line on the canvas.
 *
 * This sketch has the same effect as calling `serialPort.read(0)`.
 *
 * If your sketch needs to receive only a single value, consider using that
 * function instead of this library.
 *
 * The only advantage of the approach in this sketch is that it is simple to
 * modify it to receive a second value, as ReceiveMultipleValues demonstrates.

  ARDUINO CODE
  
  SendSingleValue

  This sketch repeatedly sends a record that contains a single value. The value
  is the value of `millis()`, modulo 32768.

  This sketch pairs well with the ReceiveSingleValue example from the
  Processing SerialRecord library
  <https://osteele.github.io/Processing_SerialRecord/>.

  You can also use the Serial Monitor to inspect the values that the sketch
  sends to the serial port.

  Things to try:
  - Connect a potentiometer to the Arduino, and send its value instead.
