Thanks for the quick reply. For a project work I am thinking to build a GPS Vehicle locater. This GPS IC will interface with Arduino and SIM card will be there, so the currect location will be SMS’ed to a web site in frequent intervals. So for first program etc I require a PC, but to run that standalone do I require PC everytime. As per the earlier reply it seems that it may work without PC. If any one has worked on similar kind of thing or info could you please tell me, otherwise I will think something else for my project.
I have saw a few good tutorials on Arduino and for every tutorial PC is required. Also will Arduino Decemilla is the good one which can do this ?
