/*
* IRrecord: record and play back IR signals as a minimal
* An IR detector/demodulator must be connected to the input RECV_PIN.
* An IR LED must be connected to the output PWM pin 3.
* A button must be connected to the input BUTTON_PIN; this is the
* send button.
* A visible LED can be connected to STATUS_PIN to provide status.
*
* The logic is:
* If the button is pressed, send the IR code.
* If an IR code is received, record it.
