changed the original program to use on IR Kit For Arduino Model: DFR0107

32 bit controller.

All keypresses are sent to the serial monitor at 9600 baud.

pulseIn is always HIGH. The phototransistor in the kit does not invert the

signal.

uses pin 13 for heartbeat debug

32 bits requires a long variable, so divided up into two 15 bit so can use

integer variables

use the first 15 bits of the 32 bits for remote and data stream

verification. This code is always the same for every button press

use the last 15 of the 32 bits for button press selection. This code

changes for each button.

ignore the middle 2 bits, it never changes.

#define IR_BIT_LENGTH 32

#define FirstLastBit 15

integer variables. Ignore center two bits. they are all the same.

#define BIT_1 1500

#define BIT_0 450

#define BIT_START 4000

#define IR_PIN 4

#define LED_PIN 13
