Light dependent resistor changes the resistance as per light intensity using this principle this project is done. Light depended resistor is attached with door frame so we can get level change as per light or no light. This output is connected with driver circuit and then it was connected with computer, so when ever door will open or close user can get information in computer and user can also select some operation like play sound etc. software part is done using visual basic language.
