/* YourDuinoStarter Example: nRF24L01 Transmit Joystick values
 - WHAT IT DOES: Reads Analog values on A0, A1 and transmits
 them over a nRF24L01 Radio Link to another transceiver.
 - SEE the comments after "//" on each line below
 - CONNECTIONS: nRF24L01 Modules See:
 http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo
 1 - GND
 2 - VCC 3.3V !!! NOT 5V
 3 - CE to Arduino pin 9
 4 - CSN to Arduino pin 10
 5 - SCK to Arduino pin 13
 6 - MOSI to Arduino pin 11
 7 - MISO to Arduino pin 12
 8 - UNUSED
 - 
 Analog Joystick or two 10K potentiometers:
 GND to Arduino GND
 VCC to Arduino +5V
 X Pot to Arduino A0
 Y Pot to Arduino A1
 
 - V1.00 11/26/13
