Sending string to LCD from a browser

Hey Everyone. This is my first post here and my first experience with Arduino (or meddling with electronics period).

Last night I was able to successfully connect to a 16x2 LCD and have it print some strings and numbers. It worked better than I expected but I’d like to move on to the next step. The strings it displays are just written into the original code and aren’t very dynamic. What I would LIKE to do is code a web application (I have a strong background in web programming) that allows me to send strings to the Arduino and have them displayed on the LCD. I’m going to guess I need an Ethernet shield for this, but I’m not sure what else to do beyond that point. Can someone point me in the right direction? Or if this has been done with an easy to follow guide I’d love to read about it.

My project goal is to use the Facebook API to display my friend’s status updates to the screen. I would parse the data to a format that can easily be printed to the LCD and would have it scroll or something else.

Thanks guys. Looking forward to making many more posts here as I continue my journey.

Good guess.

but I'm not sure what else to do beyond that point.

Should be fairly obvious to anyone with a strong background in web programming.

The Arduino will either be a server, and respond to GET requests, or it will be a client and call some server to learn what to display.

If the Arduino is a server, it can be contacted by any client anywhere.

Alright. That is what I assumed. Hardware is still completely new territory to me and I have the idea in my head that everything is worlds more complicated than it actually is. I over-think a lot of it. I'll have to read more into it and maybe purchase a shield.

I forgot to ask this, but is there a way I could do this over USB?

Open the Serial Monitor, and start typing (after programming the Arduino to read serial data, that is).

I am doing a similar project, my method is to use AppleScript to read data from and API then pass that to the Arduino to display on the LCD.

If you are using OSX then I can help a little, Windows not so much.

Message me if you would like more "Mac based" information on how to get the data from the web to the Arduino.

I have actually hit one major issue which I posted about yesterday in which the serial only seems to work when the Arduino Serial monitor is open.

I feel like this is only a minor issue and I am happy to help you with any other info.

Awesome mate. I'm a Mac user so Applescript could work. I was hoping to do it without the middle man (pc) but that could work. I'll hit you up tomorrow.
