/*
* Demo for RF remote switch receiver.
* For details, see RemoteReceiver.h!
*
* This sketch demonstrates how to use the static version of
* RemoteReceiver::sendTelegram, which can be used in low-memory
* situations.
*
* Connect the transmitter to digital pin 11, and the receiver to digital pin 2.
*
* When run, this sketch waits for a valid code from the receiver, decodes it,
* and retransmits it after 5 seconds.
