USB Web Camera

Watching live images with USB Web camera is an exciting must do when you are building robot. I assume you installed VNC server to allow you to remotely view your complete Windows system. After I learned how to capture images with fswebcam, I decided to go further where my question arose up: “How can I watch live images using the same USB Web camera?”. The answer is in the next video below.

Imagine you are watching live images while your robot is running around your garden.
