/* YourDuinoStarter Example: nRF24L01 Receive Joystick values
- WHAT IT DOES: Receives data from another transceiver with
2 Analog values from a Joystick or 2 Potentiometers
Displays received values on Serial Monitor
- 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
- V1.00 11/26/13
