I have a project where I need to detect a microsecond break in a dc signal. Given that the clockspeed of an arduino is in the MHz, would a loop that looked for a low signal, then kicked out a signal to turn on an LED be able to pick up such a short break? Thanks.


That's what interrupts are for.
Can detect a signal that is I think 2 clock cycles in duration (0.125uS).
