Taking things a little further..

[neurax]

Current programming experience:
C++ (all knowledge about object orientation)
Java (all knowledge about object orientation)
mySQL (accessors, sorters)

What I'm looking to do is 2 fold. I just purchased an Arduino UNO so that I can try and teach myself data communication and whatnot.

I managed to hook up an LCD display to my Arduino and get some communication using the LiquidCrystal.h library for Arduino.

My problem lies with the fact that nobody has shown us how to interface directly with a IC or shown us how to grab information from an external source (maybe the internet?)


Here's what I would ultimately like to do:
I want to write a program in C++ that will connect to a server or website that has weather data (temp, humidity, etc.)

I want to grab this data and then write it out to the LCD display that I have.


More or less I want to extend my programming and engineering-design skills and this is the apparent next step. If someone could give me some direction, I would be very grateful. Thanks.

I'd suggest you start looking at communication protocols and the libraries that let you write up requests in such protocols and send them off into cyberspace. You probably want HTTP, so read up on it and then look at winhttp or winsockets, assuming you are using windows.

(I have actually only programmed with winhttp but winsockets actually looks far more usable and powerful.)

You can then request the data (assuming they have some programmatic way of requesting data!) and do whatever you want with it.
