The main intention of this project is to make a system which is capable to control the electrical devices threw IR remote. This project can give help to old and physically handicap person. It also give some minutes to a very busy person
who has not time to switch off home lights.
This project is a very simple
project and have no need of programming. Any type of IR remote which is used in
TV, AC, SET OF BOX can be used in this project. IR remote is capable to sending
signal threw the blinking light with 38KHz, when button is pressed a pulse
Width modulated signal is sent remote, when this signal is received by a IR
sensor (TSOP1738/1838) , it give a response to flipflop IC which operate a
relay to make light ON/OFF.
