Hey guys,
I'm planning on automation. Then is it necessary to connect arduino to a PC? OR the below connection sufficient for automation
please help if i'm missing anything!!
Arduino runs fine by itself... do you need to control it remotely?
Cheers,
Kari
I would say you are missing a PC/mac. The PC/mac is needed to program your Arduino. 8) .....
....Och I missed you had not included your development environment on the drawing 8)
Also note that your modem must have a network cable plug. It is more likely you will have a router or switch to create a LAN which connects to the internet.
If you really mean to have a modem (so nothing else than your arduino connected to the internet), think about how you will be able to reboot the modem in case of failure.
Best regards
Jantje

yeah. Want to control it using smart phone or any other PC.
Then all you need is a project and code.

So am I good to go using above diagram?
Dear Mr. deathbyte,
You sent me three PM's within 7minutes four PM's within 10 minutes. To your first message I replied and ask to keep this discussion in the forum, with 
And your last message was "No1 replies there".
You should know that this is not a chatboard.
Now, what is your plan, what are you going to automate with your Arduino? What components you have available so far? And finally, don't power your arduino with 9V battery, it won't last long.
And finally, have you "Search" this forum? There's so many example projects already.
We will help you anyway, why not, but be patient.
Cheers,
Kari
EDIT....
If you want to control your home using an arduino,
You need a webserver...
Here you have 3 options...:
Buy a server (buy a dell, hp etc. server, write some php script and run it as a "website")
Use a server host (many dedicated or non-dedicated server hosts out there)
Use aws (amazon web services is a great way to get a free server going if your not goin to do much with it, free for one year!)
And you need some relays, i would not reccomend connecting the relays to your power outlets tho, use some king of home automation remote and power jacks and hack it.
Ps. If your gonna host a webserver make sure u got a firewall and some security so your lights dont go on and off every few seconds!

Well, that is somewhat misleading (a little short of BS). You can have the arduino act as a web server to control things via a web page. Below is some simple arduino web server test code.
//zoomkat 3-17-12
//simple button GET server code to control servo and arduino pin 5
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
//Powering a servo from the arduino usually DOES NOT WORK.
//note that the below bug fix may be required
