In This Lesson I Can Show You How To Make A Simple Door Alarm. This alarm is cheap, quick to perform, and works well. It was fun work to do and could be completed in less than an hour. Have fun with Instructable!

Parts you will need:

Dress code

2 AA batteries

Buzz

Two small screws

4 pieces of electrical cord

A piece of plastic (or other non-operative material)

Step 1: Making the Switch

Drill a hole in the 2 edges of the dresspin. The hole should be slightly smaller than the screw so that the screw can tighten. Tighten the 2 screws on the pinpin. They have to come out a little later, the power cords will be attached to this later.

Screws will act as a switch.

Step 2: Installing Batteries and Buzzer

Put a little hot glue on the clothespin and attach the battery to it. Open the dressspin, apply hot glue to it and stick to another battery.

Note that one battery has a positive pole on the left and the other battery has a positive pole on the right.

Now apply a little hot glue to the side of the dresspin and attach the buzzer to it. Wires coming out of the buzzer must be able to reach the battery and screw.

Step 3: Connect the batteries

Apply a small amount of solder flux to the battery poles. Now insert a small solder into it with a soldering iron.

Direct the buzzer connection to the battery + connection.

Connect the end of the battery to the other end of the battery.

Guide the piece of black string to the rest - the end.

Note: A simple string drawing is added to keep it clear.

Step 4: Connect the Switch

Wrap 2 wires (- from the battery and - from the buzzer) around the screens with screws. Insert soldering flux into it and connect the connection.

The noise is now buzzing! To prevent this, you can place a piece of plastic between the screws.

Step 5: Prepare a piece of plastic.

Make a hole with a piece of plastic. This can be done with a drill. Because I didn't have a proper drill, I did this with a soldering iron.

Insert a piece of string (power cord or piece of string) into the hole and lock it.

That's right!

Door alarm is ready! I put it by the door with a little hot glue. This can also be done with screw or tape on both sides, depending on the situation.

The thread is attached to the frame. When the door is opened, a piece of plastic is removed from the dressing door and an alarm goes off.
