Id like to try and investiate how I can use relays in my house to switch on some lights.
So ive borrowed my friends arduino and ethershield so I now have 2 arduino decimilia's and two shields to play with
I would like to use a webserver as the GUI to the two devices, Can anyone suggest a method I can use to link the two devices via the ethershield to the server.
Basically I would like to use my iphone to switch on two seperate lights via a web server. Does anyone have any recommendations on how to go about doing this?
I am thinking the best way to go is to get the two devices to look at the state of a database or a text file to see if they need to switch on or off, Im not sure if that is the best choice given that if they need to do a lookup ever second that will be a lot of traffic!
Would PHP or Python be able to do some kind of push notification to send a signal out to the two Arduinos?
