Home automation is a Automation technology which makes the work easier in all aspects related to home. There are different methods in wireless technology such as Bluetooth, WIFI and GSM.As we are entering in a new era of technology home automation has more significance. Automated home is also called as smart home. In this paper we have presented a Home automation using Arduino and IOT. Our project proposes a low cost solution and Home automation is done using IOT system which uses mobile devices to control an analyze the basic home functions and features automatically through internet from any corner within short span of time. ATMEGA 328 arduino microcontroller is used to upload computer code to the physical board and controls sensors, relays as well as actuators.
