Protect your room against intruders! Mount the micro switch on to any movable object to trigger the alarm. The alarm is deactivated by a separate slide switch.

This kit can be used to make a shed or room alarm when mounted on the top of a door, drawers or any other object with a moveable opening. It can also be used by replacing the micro switch with a magnetic door contact.

A micro switch acts as a trigger mechanism and is armed / disarmed by a seperate sliding switch. The door's movement is detected by a micro switch mounted onto a door or object with a lid. A timer provides an entry delay during which the system can be disarmed by the slide switch, whilst a separate timer silences the alarm after two minutes. Both of these timers are implemented via a 556 dual timer IC.

The alarm can be further enhanced by using a simple key switch for arming / disarming or by replacing the micro switch with a magnetic door contact switch to activate it. The board, battery pack & buzzer can be placed into a box designed by the student.
