- * Test send/receive functions of IRremote, using a pair of Arduinos.
- *
- * Arduino #1 should have an IR LED connected to the send pin (3).
- * Arduino #2 should have an IR detector/demodulator connected to the
- * receive pin (11) and a visible LED connected to pin 3.
- *
- * The cycle:
- *  Arduino #1 will wait 2 seconds, then run through the tests.
- *  It repeats this forever.
- *  Arduino #2 will wait for at least one second of no signal
- *  (to synchronize with #1).  It will then wait for the same test
- *  signals.  It will log all the status to the serial port.  It will
- *  also indicate status through the LED, which will flash each time a test
- *  is completed.  If there is an error, it will light up for 5 seconds.
- *
- * The test passes if the LED flashes 19 times, pauses, and then repeats.
- * The test fails if the LED lights for 5 seconds.
- *
- * The test software automatically decides which board is the sender and which is
- * the receiver by looking for an input on the send pin, which will indicate
- * the sender.  You should hook the serial port to the receiver for debugging.
- *
