PS, of course for the above test, you will need to tie your output pin of the test routine back to the input pin 2. We should ignore them. rockwallaby: You must log in or register to reply here. So for the active state we should accept only pulses with a length very close to the specified length no more, no less, and for the release state it is enough to have a minimum length, any pulse coming faster should be ignored. If you hire me for this project, you wil Electronics I want to do it for you if you want. Of course the release time before the first pulse and after the last pulse is longer since the acceptor is in waiting state.
