/*
* ReceiveAndSend.cpp
*
* Record and play back last received IR signal at button press.
* The logic is:
* If the button is pressed, send the IR code.
* If an IR code is received, record it.
*
* An example for simultaneous receiving and sending is in the UnitTest example.
*
* An IR detector/demodulator must be connected to the input IR_RECEIVE_PIN.
*
* A button must be connected between the input SEND_BUTTON_PIN and ground.
* A visible LED can be connected to STATUS_PIN to provide status.
*
