  Embedded Ethernet is nothing but a microcontroller which is able to
communicate with the network. A design of AVR controller-based embedded
Ethernet interface is presented. In the design, an existing SPI serial device
can be converted into a network interface peripheral to obtain compatibility
with the network. By typing the IP-address of LAN on the web browser, the user
gets a web page on screen; this page contains all the information about the
status of the devices. The user can also control the devices interfaced to the
web server by pressing buttons provided in the web page. This creates a network
for easy communication among the devices.
