RFmoduleRx.java
This code is for simple demonstration of the Parallax 433.92 Mhz RF Reciever (#27980)
Connect Javelin I/O pin 7 to the RF Rx module DATA line.
Connect +5v (Vdd) to the RF Rx module 5v line.
Connect ground (Vss) to the RF Rx module GND line.
This code will receive at 9600 baud, inverted.
This code is meant to run in conjunction with RF Tx module (#27981) running code set
to transmit at 9600 baud.
