1-About the webcam issue:
I know that the webcam is not controlled by arduino directly but it looks working so no problem i think.
I will use
- one LM35 to get temperature data
- an ethernet shield will be attached for internet thing
- if i use the system i talked above for webcam i will need a digital input for doorbell
- one digital for open/close air conditioner
- one digital for open/close lighting system
- one digital to open/close door lock
I think Arduino UNO can handle all of them, can it?
