/* 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:

|
||
|
|
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
