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!.

Measure of Duty Cicle of a PWM signal

Although not specifically using Arduino, my project may contain a few ideas about measuring duty cycle, espcially at high frequencies:
