this would be a excellent instructable, if it did that instruct, this is just a show off and attention grabber... final video uploads alone do not help people in building, recreating, or modifying a design for personal use. if you want to be a good contributor to the site then do so in a manner that is conducive to others and give all the information that is required so that we don't have to ask you for the parts list, code, schematics etc

sir plz tell how to make this lock system step by step plzz....
