I am trying to control an arduino board over the internet (well initially local network, I can expand it the internet myself)
I have an uno and an Ethernet shield. There is lots of information on controlling it by making the Ethernet shield a web server and accessing it as html.
The way I want to control it is to have a set of variables that is accessible over the web, suggestions on how to go about this would be grateful. I was thinking just have them in a web page or a database of some sort.
Anyway, basically I want the arduino to be able to check a set of variables on the web and use those variables as inputs, for example (variable led_1 = 0) so the arduino fetches the value of 0 from the web and sets the local variable of led_1 to 0.
A bit long winded but any info on how I can approach this would be much appreciated, thanks.
