/*
|
|
* 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.
