00003 * Title: NBitWonder Binary Counter Code Example
00004 * Description: A binary adder implemented using the mbed embedded development platform.
00005 *       This program utilizes the mbed's 4 onboard leds to represent the value of a 4-bit
00006 *       binary variable. The variable begins at 0 and is incremented once every second.
