//#include <SoftwareSerial.h>

//For Atmega328P's
// XBee's DOUT (TX) is connected to pin 2 (Arduino's Software RX)
// XBee's DIN (RX) is connected to pin 3 (Arduino's Software TX)
//SoftwareSerial XBee(2, 3); // RX, TX

//For Atmega2560, ATmega32U4, etc.
// XBee's DOUT (TX) is connected to pin 10 (Arduino's Software RX)
// XBee's DIN (RX) is connected to pin 11 (Arduino's Software TX)
//SoftwareSerial XBee(10, 11); // RX, TX
