Technology is a never ending process. To be able to design a product using the current technology that will be beneficial to the lives of others is a huge contribution to the community. This paper presents the design and implementation of a low cost but yet flexible and secure home automation system. The design is based on a stand alone Arduino UNO board and the home appliances are connected to the input/ output ports of this board via relays. The communication between the cell phone and the Arduino UNO board is wireless. Home applications like bulbs, windows, water motors , automatic door locking systems etc. are controlled using AHA. The main motive is controlled home appliances in smart homes with user friendly, design at low cost and simple installation. Password protection is being used to only allow authorized users from accessing the appliances at home.
