I am experimenting with making an analog video signal into an "on or off" state which will basically say, does it have a video signal.
Would using a full-wave rectifier with a capacitor for smoothing be a viable option? unfortunately I can't afford an oscilloscope to test video signals, so I just wanted to ask if I am on the right track. I know I can probably just use my multi-meter to read it once I have the rectifier created...but I also understand very little about video signals and circuits in general (although I am learning a ton and reading a lot)
also, would reading this just be a matter of having the output of it go into a analog Read pin on the arduino since it shouldn't go over 1v?
