The project is designed to operate electrical loads using an IR-based TV remote. The TV remote transmits coded infrared data which is then received by a sensor that is interfaced to the control unit. The system operates electrical loads depending on the data transmitted from the TV remote.
RC5 based coded data sent from the TV remote is received by an IR receiver interfaced to an Arduino board. The Arduino Atmega328 microcontroller processes command and performs switching operation of electrical loads through ULN 2003 current driver.
The loads are interfaced to the control unit through the relay contacts. The system can be used in existing domestic or commercial areas for either operating the loads with the TV remote.
