Hi there I am very new to electronic projects. I am really interested in making my door an electric One. I mean i have got my room door which locks/unlocks with a key, but i want to lock/unlock this with my Computer. I can do the programming part, but making the hardware is a problem for me. I need some guidelines on how to start doing this? DC Motors may be? Its ok if i have to make the lock from the scratch. Any Suggestions ??
