Home-made Box With Alarm

Introduction: Home-made Box With Alarm

Hi!

I made a simple box with alarm.

You need:

Reed switch
Magnet
Plastic box
Buzzer
Resistor (if necessary)
Flashing LED
Button
Batteries (x2,3 or more).

Connect everything like this:

<--Batteries----Button-----Buzzer-------------Reed switch------>
     -           +                   |                    |
                                 Resistor            |         (magnet)
                                       |                    |
                                    LED-----------  |
