10+ years old sketches of different cheap optical motion detection approaches.
Important
It's not a project, just old sketches Leave here as an archived collection, just in case
It was really old one research and goal was to find cheapest approach that allow make a judjement, if picture on TV screen freeze or still palying
Motion sensor based on image processing, using OV7670 camera module and Arduino Nano board
Using ADNS-5030 Optical Mouse sensor as camera to grab image
Just experimental test of 2x2 pixel handmade optical sensor of 4 photoresistors with lens
