00002 * MBED code functionality, including idea of modulating PWM signal, taken from
00003 * https://os.mbed.com/users/viswesr/code/DSLR_Camera_IR_Remote/
00004 * As the given values did not work on the Nikon D3300, they were modified,
00005 * parameterized, and put into library form.
00006 * 
00007 * Inspiration, default values, and an Arduino validation signal were taken from
00008 * https://bayesianadventures.wordpress.com/2013/08/09/nikon-ml-l3-ir-remote-hack/
