Home Automation DIY project using Arduino UNO & Ethernet Shield

details

1. Project Description

The author implemented Home automation based on web server using Arduino and Relay. He would like to be able to turn on and off home appliances such as TV, Fan, Light, and Computer.

webserver

The heart of this project is Ethernet shield and definitely the brain of this project is Arduino uno board they both work together to Turn on and off the contacts of relay to control the desired outputs . Relay is like a magnetic switch to make a contact closed and open depends upon on magnetic field the arduino board will send pulse like 1 (ON) mean high to the respected relay or will send 0 (OFF) to connected relay to turn off the load.
