Hi... I'm asking you guys because i have a serious problem. I'm about to make a project in school and i don't quite know how to get started on it...
I would just say before you start accusing me of cheating that i came up with the idea for this project by myself.
But here we go... I have chosen to make a door alarm that works by placing a magnet on the door and and a magnet of the opposite charge (+/-), on the door frame. When the door is opened without shutting down the magnets the alarm sounds...
Here comes the tricky part
I want it to work so the two different poles creates a field of magnetism that is strong enough to work over the opening in a door!
Hopes it makes sense... If not, ask me!!!
