hi
i want to connect a web camera with atmega16 or with something is more advanced . How will i do the connections and how should i start
thank you very much

 

You should start by saing what you want to do next once you somehow connect the camera to it. Atmega will probably not be too good a choice, the only realistic thing that I think it is able to do would be some simple shutter control based on lighting conditions, but even that might be a stretch.

 

you'll probably be looking at a USB host that will port packets off to a more capable processor, or stuff data into a file at some very limited rate.

 

Atmega may be capable of doing 1mbps throughput on uart, without any complex data manipulation. If the camera is 640*480, then that leads to maximally ~3fps just from that. And that is straight through, it has nowhere near enough ram to hold a frame, or enough time to use external ram.
