yuhki50 0:70c8e56bac45 2 * Test send/receive functions of IRremote, using a pair of Arduinos.
yuhki50 0:70c8e56bac45 3 *
yuhki50 0:70c8e56bac45 4 * Arduino #1 should have an IR LED connected to the send pin (3).
yuhki50 0:70c8e56bac45 5 * Arduino #2 should have an IR detector/demodulator connected to the
yuhki50 0:70c8e56bac45 6 * receive pin (11) and a visible LED connected to pin 3.
yuhki50 0:70c8e56bac45 7 *
yuhki50 0:70c8e56bac45 8 * The cycle:
yuhki50 0:70c8e56bac45 9 * Arduino #1 will wait 2 seconds, then run through the tests.
yuhki50 0:70c8e56bac45 10 * It repeats this forever.
yuhki50 0:70c8e56bac45 11 * Arduino #2 will wait for at least one second of no signal
yuhki50 0:70c8e56bac45 12 * (to synchronize with #1). It will then wait for the same test
yuhki50 0:70c8e56bac45 13 * signals. It will log all the status to the serial port. It will
yuhki50 0:70c8e56bac45 14 * also indicate status through the LED, which will flash each time a test
yuhki50 0:70c8e56bac45 15 * is completed. If there is an error, it will light up for 5 seconds.
yuhki50 0:70c8e56bac45 16 *
yuhki50 0:70c8e56bac45 17 * The test passes if the LED flashes 19 times, pauses, and then repeats.
yuhki50 0:70c8e56bac45 18 * The test fails if the LED lights for 5 seconds.
yuhki50 0:70c8e56bac45 19 *
yuhki50 0:70c8e56bac45 20 * The test software automatically decides which board is the sender and which is
yuhki50 0:70c8e56bac45 21 * the receiver by looking for an input on the send pin, which will indicate
yuhki50 0:70c8e56bac45 22 * the sender. You should hook the serial port to the receiver for debugging.
