Video projector project using motion detector

Hi,

I'd like to create a video projector project using an Arduino, motion detector, video projector and laptop.

E.g. someone walks into a corner of a room, motion detector alerts the Arduino, which then tells the laptop to start playing a video file.

Does anyone know how to go about this, if there are any Gits that exist or compiled code that I can use for this project? Any help would be great!

I'm running OSX but can use Windows if need be.

Thanks :slight_smile:

I would look at the Processing language for the laptop to trigger the video when it gets a signal through the serial port from the Arduino.
Attach a PIR sensor to the Arduino.

It should not be hard at all. It is not worth looking for the code, shouldn't take you longer than fifteen minutes to write exactly what you want.
