for an art project i'm trying to do i am broadcasting my on own RF signal using a blonder tongue modulator and simple antenna'd TVs. From the modulator I have a lot of options for video sources: cameras, VHS and DVD players, laptops, and Smartphones.
however for the project i'm expected to integrate arduino into the process. what i would LIKE to do is find a means of taking sensory input, most likely with an ultrasonic range finder, to interrupt the RF broadcast at certain distances. is this entirely impossible? my research so far makes it seem like it might be much too complex for a beginner.
i dont necessarily want the arduino to manipulate the video data itself, but more so the transmission. if that interruption can happen at the level of RF signals or involve the particular video source (VHS, DVD OR laptop) i would be more than happy and willing to attempt either.
thanks for any help or suggestions!
