helloworld_rx.ino

Simplest possible example of using RF24Network. Put this sketch on one node, and helloworld_tx.pde on the other. Tx will send Rx a nice message every 2 seconds which rx will print out for us.

const uint16_t this_node = 00;   // Address of our node in Octal format (04, 031, etc)
const uint16_t other_node = 01;  // Address of the other node in Octal format

  unsigned long ms;
  unsigned long counter;
