Automatic light switch for house / Muhamad Firdaus Hussain & Muhamad Azri Haziq Mohd Suhaimi

This automatic light switch for house is built to make an improvement to our classic light switch. this automatic light switch will detect the magnetic field by using the reed switch. The design will provide the user to use either in automatic light switch or in manually. This is because of we had created the indicator by using Arduino to controlling the LCD screen. Whenever this indicator turn on, the user can use the automatic light switch but when it turn oft: the user only had to use as a manually to switch on the light. The circuit bad been developed in Proteus. When the power source is on and the reed switch will detect a magnetic wave it will supply the voltage through the IC741. IC4017 will be working as counter as for our project it will count twice before activating the LED circuit. In our project also use the Arduino for controlling the LCD that we use as indicator for user to know if our system is ON state or OFF. This automatic light switch have been working well, it can detect the opening n closing of the door that have been attached with magnet twice before the light turns ON and OFF. The Arduino also activate the LCD when the user switch on the power source for indicate the automatic light system is working and word "ON" will appear on the LCD according to the program that we had write for the Arduino.
