I have an upcoming project where i need a motion sensor to change a video projection from a black screen to another video. I am wondering what the best approach would be. The project will be running for 2 weeks for 12 hours a day, so I would prefer not to use my laptop. would it be complicated (or possible) to get a dvd player to change chapters with arduino? any suggestions would be much appreciated! thanks!
oh, i'm really new to the software. and the hardware.
