Are you looking for a device that can be used to control various household appliances (like fan, rice cooker, lights, etc) using your TV or DVD remote control? If yes, this is the project you are looking for. This is based on Atmega8 microcontroller. The microcontroller gets control commands from a DVD remote through IR link. Each time an appliance is turned ON/OFF, its status is stored in the internal EEPROM location so that it can be accessed later in case of power failure.
