I have one idea that I know is possible, but I am looking for a more simple solution if possible. I want to control an arduino through a web interface. For example, an iPhone or netbook would scan for a wireless network. If would see one called Arduino that it could connect to. Once connected the only web page available is what the wifi server is serving. The webpage controls the arduino - for example, controlling the color of an rgb led.
Right now my plan is to get a fonera wireless router because it only need 6V and it has a serial port. Also OpenWRT can be installed so I can run apache and a webserver on it. Using phhserial I can have a webpage talk to the arduino through serial.
What I would like is to get rid of the router. A wifi shield that attaches tot eh arduino would be perfect. But then the arduino needs to be a wireless AP and it needs serve webpages. WiShield like it might work - however can you make the arduino an access point. Can you make it force what webpage shows up when someone opens a browser? If so any code examples out there?
