Hi, I want to read de the duty cicle of a PWM signal with Arduino. I would like to use interrupts to detects the change of high to low and low to high. I worry if it's possible to use the timers of arduino as counters to read the time which the signal is in high and low. Thanks!.

Maybe something like the attached will help as a starting point.
