Abstract: Technology may be a never ending method. To be able to style a product exploitation this technology which will be useful to the lives of others may be a immense contribution to the community. This paper presents the look and implementation of a low value but nonetheless versatile and secure mobile phone based mostly home automation system. the design is predicated on a Arduino uno R3 & Bluetooth and also the home appliances area unit connected to the input/ output ports of this board via relays. The communication between the mobile phone and also the Arduino is thru hc 05 bluetooth module. this technique is meant to be low value and scalable permitting style of devices to be controlled with minimum changes to its core. secret protection is being employed to solely permit authorised users from accessing the appliances reception
