I am very new to Arduino, and was wondering if there is any way to use the ethernet shield to send data from the Arduino straight to my macbook, without an internet connection. Basically, I have several sensors connected to my Arduino, and I want to be able to read data from them on my laptop from a long distance (~100-200 ft, I understand that Cat5/Cat5e can transmit signals that far). This data then needs to be sent to a program written in C++ in order to display on-screen in a UI. Is this possible? Thanks in advance,
P.S. Can I use the ethernet shield and video experimenter shield (http://nootropicdesign.com/ve/index.html
) with one Arduino at once, or do I need two?
P.P.S. This is completely unrelated to Arduino, but does anyone know if there is a way to view composite RCA audio-video on my mac live? Possibly through use of a RCA to USB converter?
