/*
*   Sofware Serial test code for Bluetooth module
*   This code reads incomming data and sends it back over the Software serial line.
*   Next it turns the internal LED on when the received data is 1.
*   It turns the LED off when the received data is not 1.
*   This code is based on the work of Cody Bradly at http://www.ernstc.dk/arduino/tinycom.html
*   and on the SoftwareSerialExample Tom Igoe
