We live in a world of communications and in a constant process to transfer communication technologies to other platforms that can be used by intelligent machines like robots. In three steps can be built a powerful communication system by plugging the Ethernet module into the Arduino board, create network connections, and building the application for data transfer.Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data. Full-duplex transmission necessarily implies a bidirectional line (one that can move data in both directions). We have developed the project which uses UDP protocol for communication between two Arduino UNO boards through Ethernet cable.

Touch screen based Appliances Control System is used to control various electrical appliances in our home using a touch screen panel. Although this project is aimed at controlling home appliances, it can also be used in industries and colleges. We have used 2 relays in which we have connected a bulb and a fan. This project can control both AC  and DC devices. User has to use a touch screen which acts as control panel for sending commands. These control commands are then sent through a wireless RF communication module.
