/*
*   Group Sofware Serial Node LED code
*   This code reads incomming data and sends it back over the Software serial line (if needed).
*   Next it turns the internal LED on when the received data is its ID.
*   It turns the LED off when the received data is 0.
*   This code is based on the work of Cody Bradly at http://www.ernstc.dk/arduino/tinycom.html
*   and on the SoftwareSerialExample Tom Igoe
