Hello. What is input capture? What would be the simplest way to demonstrate input capture and what would be the basic theory behind it(basic idea, pins used)? I have a development board and I can run cables from one pin to another. My understanding is that I can create a PWM signal with a certain frequency and duty cycle and then output it on pin OC1A or OC1B. I could run a wire to pin ICP1. But what then? How do I know I captured anything and what would be a good way to show that I captured it? How do I show I captured a signal with a 60Hz frequency or 50% duty cycle for example?
