Project must be wireless
because my project has to supply controlling my light in other cities via internet.
In this case i want to give a static IP to my light.
The close by part is when i run my android application on my phone, it connect with arduino and do what i want(open or close light). And also this part will be wireless.
Arduino for this project must supply ADK, and i found 'Arduino Mega ADK'.
For controlling for other cities need 'Arduino Ethernet Shield w/o PoE R3'. But i dont know what can i use when i close by? dont know Ethernet shield is enough for it? If not enough, i need wireless shield or bluetooth shield?
That might be a little tough, light's do not know what IP addresses are. So we know you need to control this over the internet, which means you'll have to have an internet connection. So as far as a static IP address goes, that's going to depend on your ISP. Of course, if you are going through a router with NAT (most have this), then you will also need a local static IP, which is easy enough with Ethernet/WiFi.
