I would like to tell you that I'm not a noob. I am using Arduino Uno for quite some time and already successfully wrote several advanced programs (without help from others). So this is my first post, when need some help, because I didnt find satisfactory answers on the Internet
My brother asked me to participade on hardware solution for highly specialized let me say "sensor site" for municipal use. Because work assignment was to be completely open-source sw and hw device, Arduino seems to be the simpliest and best solution at this time.
Each device will be arduino with few sensors, character LCD and ethernet shield. Every device will show its measurements on LCD and on specified local webpage but we need to know whether standard Ethernet Shield can do:
1.) send a web page (static html) not only locally (know that local broadcast is possible), but also directly to the Internet network (multicast) - to give access from anywhere, not just form local network.
2.) send "data stream" - to enable data to be fetched directly from one server (we dont want to parse html with servers...)
3.) whether it is possible to run local and internet broadcast at a same time (i.e. after delay but still in one program loop).
4.) how many pins (and which ones) are used by etherne :smiley-eek:t shield? Sorry, already found this somewhere but lost it again...
I am asking because I dont have ethernet shield and never used it - we will purchase it with arduino in few days after all of last details will be checked .
Thanks for ALL answers !
