danbudanov 1:bdc12143ced7 2 * MBED code functionality, including idea of modulating PWM signal, taken from
danbudanov 1:bdc12143ced7 3 * https://os.mbed.com/users/viswesr/code/DSLR_Camera_IR_Remote/
danbudanov 1:bdc12143ced7 4 * As the given values did not work on the Nikon D3300, they were modified,
danbudanov 1:bdc12143ced7 5 * parameterized, and put into library form.
