Hey friends in this tutorial I will show you how to make Home Automation System which can be controlled with Smartphone as well as Manual Buttons. In this project we will be storing data in the EEPROM Memory of Arduino so when there is any power cutoff and when the power is back again it will continue the last saved state.
I would recommend to buy a PCB for this project as it is very compact, with clean and neat connections. and the PCB we have used in this project is universal PCB and It can be used in other projects as well it has Bluetooth + IR + Manual Switches connectivity.
