how to control home appliances using MOBILE, REMOTE AND SWITCHES | CREATIVE ELECTRONICS |

 

Hey friends in this tutorial I will show you how to make Home Automation System which can be controlled with Smartphone, IR Remote and 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.
