Hello. I'm a bit of a newbie to these shields, and i cant quite figure out whether or not this shield will give me the ability to make http calls. http://www.let-elektronik.dk/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=160&category_id=27&option=com_virtuemart&Itemid=85
Also, is it compatible with the arduino uno?
Thanks in advance!
