Read a string by BARRAGAN http://barraganstudio.com
Demonstrates how to read a string from the serial port It is important to use delimiters in the String to read for example read data until a '\n' or a designated character is found This example reads data from the serial and stores into a String variable until an 'L' is found, 'L' will be used as a terminator for the string for testing with the console Send. Change the 'L' for whatever delimitator you might want to use in your strings.

    char val; // variable to receive data from the serial port
    String data = "";

    void setup()
    {
      Serial.begin(9600); // start serial communication at 9600bps
    }

    void loop()
    {
      if (Serial.available())  // if data is available to read
      {
        val = Serial.read(); // read it and store it in 'val'
        if (val != 'L')      // if not an 'L'
        {
          data += val;       // add it to the data string
        }
        else
        {
          // if 'L' was received (our designated termination char)
          Serial.println("string received: " + data); // print the stored string
          data = ""; // empty data for next string reading
        }
      }
    }
