Hello to all!!!! I am new to raspberry pi as I had done projects on Arduino. I need to make time lapse camera using my usb cam to monitor my room. The system should start photography in the time lapse of 500 ms when any person will enters into room and it should store on the sd card. And it should stop when nobody will be in room. I don' t want to upload the photo on server. I just want it to be on sd card. I am thinking to use PIR controller.
If it is possible then please guide me with code and required hardware.
