1. On the Computer that the server is supposed to run: 1. Connect to Internet2. Go to “what is my IP Adress website and check the current IP address3. Run the Server Side Processing Code

2. On the Computer that the client is supposed to run:1. Connect to Internet2. Change the IP Address variable to the one that is provided from the server

computer3. Run the Client Side Processing Code

Controlling the Screen based on Distant User InputObtaining IP Address of the Server : http://whatismyip.com/

IP Address (Internet Protocol Address): This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network. There is a standard of communication which is called an Internet Protocol standard (IP). In laymans terms it is the same as your home address. In order for you to receive snail mail at home the sending party must have your correct mailing address (IP address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet. Without this specific address, information cannot be received. 4

Actuating the Physical Space and Monitoring the Physical Properties of the Space at the same time

Things that Talk to EachotherConnecting Two Arduino Together

Master Slave

Master Arduino Can control the Slave Arduino by Sending Data to it. Thus it is better to connect the devices that monitor the space and sense the changes in the physical properties of the space to the Master one and connect the Actoators of the space that are activated based on sensed changes in physical properties of the space to the Slave one

Master/Slave connection is one way if you are short in digital or analog pins and have more sensors and actoators than the pins that are available on one Arduino 19
