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