Oh, DuaneB has a lot of stuff. Could you point to something more specific, if to you not difficultly. it's hard for me to understand all this articles.
At my Spektrum i have a button. I want to control a camera with this button, but a receiver operate with PWM, not with a logic "YES" or "NOT". I found a IR-control library for my camera, but i have no information about PWM control from reciever to arduino. This is my situation, i hope, that somebody already solved similar problem. But i cant find info about it on russian community
