The Arduino generates an accurate 1 second time base for the counter by cascading timer0 and timer2. The link between digital inputs 3 and 4 connects the output of timer2, 250 Hz, to input of timer0. Timer1 is a 16 bits timer, it overflows at the count of 2 power of 16, that in turn advances over-flow register. At the end of the 1 second the 16 bit register is recorded. The Arduino sends via OTG cable or adaptor 4 bytes that contain the measured frequency. The specs recommend input up to 6 MHz, I tested it at 2 MHz.
