 *  This code demonstrates how to use the NRF module to
 *  receive simple data from another NRF module.
 *  
 *  Note: This code requires another Arduino transmitting data
 *  from another NRF module using the Simple_Transmit Sketch
 *  
 *  Note: This code requires the use of the RF24 Library. 
 *  You can easily download this library in the Arduino Library Manager.
